Hoist mast
The square mast c/c 450 x 450 mm. The mast is constructed of
tubes and frames of high tensile steel and fabricated in lenghts of1508 mm. Each section is provided with one or two bolted
rack(s) module 5 and the sections are bolted together with bolts
and nuts.
The four guiding tubes and possibilities with two racks give
dual car set up advantages.
The ties are attached to the frames of the mast sections or alt. to
the rear mast tubes(only at single cage). The other end to special
brackets attached to the wall or slab. The tie length is telescopic
adjustable within different intervals. The ties can also be inclined
from the horizontal. Specifications for each particular mast tie
can be found in chapter H.
Mast sections and mast ties are galvanizing with the
exception of the mast section rack.
The hoist stops automatically at the top and bottom by means
of cams attached to the hoist mast. The cams activate the
normal limit switches located on the hoist car. Additionally
there is a final limit switch activated by separate cams at thetop and bottom of the hoistway.
The final limit switch controls a main contactor, which
switches off all three phases of the main power supply to the
drive motor(s).

Drive unit
A compact unit with two pinions engages the rack of
the mast. Each pinion is fitted to a high efficiency spur
gear box driven by a flexible coupling, by a direct startor frequency controlled, squirrel cage induction motor
with built-in electromagnetic disc brake.
The drive unit is connected to the car by pull rods.
The connection between car and drive unit means that
the hoist is prepared for an overload sensing system
(OSS).
The safety device is completely independent from the
drive unit and installed inside the car with one or two
pinions engaging the rack. The device is actuated by a
centrifugal weight and stops the hoist if normal rated
speed is exceeded.
FC VS DOL
Frequency controlled electric motors give:
– better (softer) riding comfort when starting andstopping.
– better stopping accuracy.
– less brake wear.
– hoist speed can be reduced during installation and
inspection procedures, which is not possible withdirect on line (DOL) started electric motors.
– less starting current.

Cable guiding device
Type cable collecting basket
The trailing cable is coiled into a basket. U-shaped guides with
plastic springs along the hoistway.
Type cable trolley on the mast beneath the car
To be able to control the cables and to overcome the voltage
drop in the power cable at high lifting heights, the power cable
and control cable are fixed firmly to the mast from ground level
to a junction box in the mast halfway to the mast top.
The trailing power cable from the junction box to the cable
bracket on the car is tensioned by a cable trolley located beneath
the car and travelling on the same guide members as the car.
This hoist must be installed on a concrete/steel pit or the
entrance gate of the ground enclosure has to be raised to the
height of the trolley.
The method described above is also used for hoist installations
in harsh surroundings with highwinds, low temperature etc

Control system
Two different systems are available::
a) Operator control system with relays and contactors For
DOL drive.
-Operation from the car only by a joystick for travel up
and down. Automatic stop when joystick released.
-Operation from car with joystick with selfholding relays for
contactors.Stop next landing command to be given with
push-button.Needs cam curves at intermediate landings.
b)
Semi-Automatic control system.This is a control system for FC drives developed to work
without any landing cams.The position of the hoist
is determined by generated pulses by the encoder attached
to electric motor.
The machine is operated from the hoist by using Up, Down
and Stop Next Landing by push-buttons.This systems
ensures automatically a good landing accuracy.

Landing equipment
In the ALIMAKHEK access system mechanically
and electrically, interlocked double-leaf swing doors areincluded. Or mechanically locked and electrically
monitored horizontal sliding gates at the landings.
The landing equipment can be installed by
connecting them to special brackets at the
landings, in openings,on projections or facade
scaffoldings. It can also be installed on vertical
scaffold pipes parallel to the mast from the
ground enclosure to the mast top.
The electric interlocking of the landing equipment is
connected to the control system of the hoist (stop
circuit).
The hoist calling is controlled by wireless
communication.
Included electric material is of protection class IP 54
or higher.

Safety equipment
Automatic stop at top and bottom landings
At top and bottom landings, limit cams are mounted on the
mast. These cams activate the limit switches, which auto-matically stop the hoist. The function for the up and down
limit switches are backed up by a final limit switch with its
own cams at mast top and bottom.This provides extra safety if
nomal limit switch fails.
On CN market is this switch of 3-phase type,other markets
do have 1-phase type.
Below the bottom landing level, close to the hoist mast,
buffer springs are located for the hoist car. The buffer is
designed to stop a descending hoist beyond its normal limit of
travel.
Safety details on machinery plate
On the machinery and safety device plates, heels keep the
pinion of the machinery and safety device constantly engaged
with the rack on the hoist mast, in case a counter roller or a
guide roller on the cage comes off.
Safety hooks
To prevent the hoist from climbing off the mast during
erection or dismantling, or to prevent the pinions from
disengaging the rack in case a counter roller or guide roller
comes off, safety hooks are mounted on the drive unit and on
the car. The safety hooks are placed underneath the drive
pinion of the machinery, preventing the hoist from falling off
the mast should the drive pinion run off the top rack..

Door interlocks on hoist and landing doors
Hoist doors/ramps and/or landing doors/bars are all electrically
interlocked. If any of the ”doors” are unlocked or opened, the
hoist will not operate until the door is closed.
A mechanically interlocked car or landing door cannot be
opened unless the hoist has stopped at the respective landing.
Safety device
The hoist has a unique well proven safety device which
smoothly stops the hoist on the mast should normal
driving speed be exceeded.
The safety device has a shaft with a centrifugal weight and a pinion constantly engaged with the
rack on the hoist mast. When the centrifugal weight activates, the brake cone is screwed in against
a brake lining inside the safety housing.The hoist is brought to a smooth stop, and simultaneously
the power to the drive motor is cut off..
In case of guide roller failure there are separate safety hooks provided which prevent the pinion of
the safety device from disengagement with the rack.
Phase failure relay
The electric equipment is protected by a phase failure relay,which means that the hoist can only be
driven when correct phase sequence is connected.

Optional lifting tool for use with on site cranes
The preferred method of assembling the lift system is the use of
a crane with sufficient lifting height
3 – 5 mast sections (never exceeding the mast’s freestanding
capability) can be assembled lying on the ground before beinglifted to the mast top and assembled.
We recommend attaching the load according to the figure in
order to avoid driving the car to the top of the mast in order to
disconnect the load from the crane hook.
The user’s own protective measures
Protection at the landings
It is recommended that overhead protection is furnished at
landing entrances to protect against falling objects
Scaffolds and other gangways close to the hoistway
Scaffolds and other gangways and platforms close to the hoist-
way shall be provided with enclosures according to local
regulations.

Foundation
The hoist can be installed on a gravel bed, a concrete
slab or in some cases a foundation pit is required.
Concrete slab
A concrete slab is to be made according to the following
instructions, and according to the actual model of hoist
It is important that the mounting holes of the foundation
frame are brought in level with the completed concrete
surface, and that the concrete is vibrated thoroughly –
especially around the foundation frame.
I t is also important that the fi nished sur face is plane
and horizontal.
The foundation may be made in any of the following
ways, depending upon the finished concrete level
compared with the ground level.

Minimum 30 mm concrete cover or
according to local regulations
Concrete slab on the ground
Advantage: No drain required
Disadvantage: High sill
Concrete slab level with the ground
Advantage: No drain required.
Disadvantage: Sill.
A concrete slab level with the ground is
the most common type of foundation. A
ramp up to the level of the sill is usually
made of fill, wood or steel.
Concrete slab below ground level
Advantage: No sill between ground leveland hoist car.
Disadvantage: Corrosion if water remains
on the foundation and does not
drain
IMPORTANT: Please note that the
foundation must always be
isolated, or the surrounding soil
prevented from freezing, if there
is a risk of frost heave.

Extra reinforcement of concrete slab
– for hoist with landing equipment on vertical pipe support
The concrete slab must have additional reinforcement in
order to carry the extra load due to the vertical pipes,
landing equipment and the extra load, due to thelandings (people, buggies, materials,etc).
The extra reinforcement is only necessary within the
areas shown in the picture below. The layer of
reinforcement should be placed 20 mm below the upper
edge of the slab.
Note that a concrete slab which forms part of a
foundation pit does not require this extra
reinforcement.

Mast ties
The ties are usually mounted with anchoring details or
with bolts through bearing walls, e.g. archs, balconies,steel or concrete beams. If you intend to use embedment
anchorings, these must be prepared well in advance
before erection. Note that the wall must always be
dimensioned to take up the reaction forces of the ties. .
Arrostramientos
Los arrostramientos tipicamente van montados con anclas o contornillos traspasando paredes, arcos, balcones, vigas de ascero o concreto.Si intentan usar anclas enterradas, estas deben ser preparadas de antemanoantes de la instalacion. Note que la pared siempre debe ser dimensionadapara soportar las fuerzas de reaccion de los arrostramientos..

Reaction forces
Maximum reaction force P in the wall anchorage of the tie can
be calculated as follows::
Rx and Ry according to the table on page H3.
P must never exceed Pmax indicated for each size of mast tie
according to table on previous page.
Attachment of ties
The ties are attached to the building by bolts, washers and
nuts into the holes which are drilled at the installation or
embedment sets or other approved suitable wall bracket
attachments.
Cast in place inserts must be installed prior to the hoistinstallation in order for the concrete to cure properly and
reach its proper strength. Concrete must be of suitable
strength for calculated loads (See Reaction forces). Care
must be taken in locating the inserts at their proper
location (See type of mast tie).
If other type of bolt is used such as epoxy cast in bolt or
expansion bolt, it is important to choose an approved type
which can take the calculated force in this application
with a
satisfactory safety factor.
Specifications for this type of attachment should follow
the
manufacturer’s recommendations and be approved by the
governing authority for their use.
Wall brackets can be installed either on slab...

Preparations before installation
To install your rack and pinion hoist as efficiently and safely
as possible and at lowest cost, it is important that the
following preparations are made before the erector is calledand the installation is started.
Permission
Make sure the chosen site of erection meets the
requirements set out by local authorities for safety and
inspection and that their permission, if necessary, to install
the hoist has been obtained.
Erection place
Prepare the installation site so that electric power, light,
lifting equipment and tools are available and there is
adequate access for the lift transporter – beware of overhead
obstructions.
If possible, prepare for the installation of ties and landing
accessories such as supports, platforms and railing. Suitable
places for attaching the ties are vaults, balconies or other
concrete or steel structures. See applicable installationdrawing.
Remember that these structures must be strong enough to
absorb the reaction forces of the ties and landing door
assemblies.
All mast sections should be stored on dry firm ground and
as close to the erection place as possible.
FoundationPrepare the foundation with parts required for fixing the
base frame of the mast. See chapter ”Foundation” in the
manual Technical Description.
IMPORTANT!
Make sure before casting the foundation that the
measurement between the foundation frame and the face of
the hoistway corresponds to the ties to be used.

Arrangement of power supply
Direct On Line (DOL) starting of electric motors results in a
very high starting current. The current must overcome theresistance in the cables which results in a voltage drop. This
voltage drop occurs not only in the trailing cables, but also in the
power supply cable installed between the jobsite distribution
board and the electric panel ”B” at the base. The total voltage
drop is the sum of the voltage drop in all the cables. The
consequence of the voltage drop is a substantial reduction in the
output torque of the motor.
In order to avoid starting problems it is of the utmost importance
that the main power supply is adequately sized with respect to
the starting current and the voltage drop. The following data
should be noted:
– During starting conditions, in the upward direction with
rated load, the voltage drop must not exceed 15% of the
rated voltage when measured at the motor terminals. In the
Base panel, the voltage drop of the incoming power supply
terminals must not exceed 3% of the rated voltage during
the starting conditions.
– Once the rated speed is established during upward travel
with rated load, the voltage drop must not exceed 5% of the
rated voltage when measured at the motor terminals. In the
Base panel, the incoming power supply voltage should, in
practice, not drop at all, i.e. not exceed 1 – 2 % drop..
– Except for the above mentioned supply voltage levels
during start and running conditions, the quality of the main
power supply to the lift/hoist must be in accordance with
the requirements of EN 50160:1999.
Client’s power supply
Supply cables to hoists with DOL or Y/D starting
The 3-phase power supply cable from the jobsite distribution
board to the ”B” panel at the base can be calculated from the formulas below. The formulas are applicable for the most

common types of hoists having 1 or 2 motor drive machinery
with DOL- starting at 400V, 50Hz and 460V, 60Hz.
Note If an earth leakage circui t breaker, ELCB, (ground fault
cir cui t breaker) is to be used, the tr ip-ou t value shoul d bechosen for equipment protection i.e. 500mA.
Use of 30mA ELCB is not recommended as it continuously
trips due to the motor starting current.

Note – if a lift/hoist is connected to the main power supply via a
step-up transformer the following must be fulfilled !
-DOL operated electric motors must be dimensioned for the
particular step-up transformer.
-Check the connection on the primary side of the control
transformer. Reconnect, if necessary, and measure to ensure
the voltage on the secondary side.
-All additional equipment connected to outlets must be
dimensioned for the particular step-up transformer. Voltage
level on the 3-Phase outlet will be the same as delivered
from the step-up transformer.

Voltage drop in the power supply
Typical symptoms
– The hoist will not start with the full rated load.– The brakes will not lift when starting in the Up-direction.
– The contactors oscillate on and off (”shatter”) when starting
with full load in the Up-direction.
– The contacts of the Up and the main contactors are
damaged.
Steps to be taken to overcome a voltage drop problem
The best method to avoid any voltage drop problem is to make a
proper engineering review of the conditions at the job site
before installing the hoist. When installed, the options are
limited.However, should a situation occur where the power
supply seems to be insufficient, it is important to determine
whether this depends on the voltage drop in the power supply or
something else. Use an instrument to measure the incoming
power supply voltage in both the B-panel at the base and the M-
panel on/in the car. Take the readings during starting
conditions in the upward direction with rated load in the car. If
the voltage drop exceeds the values given above, one or more of
the following steps can be taken:
1. Increase the conductor size in the power supply cable fromthe jobsite distribution board to the B-panel at base.
2. Increase the conductor size in the trailing power cables
between the Base panel and the car. Due to mechanical and
performance reasons, the conductors in the trailing cable
should not exceed 16 mm ²
The fixed cable to the junction box at 1/2 lifting height can
be increased in size.
3. Reduce the rated load
4. Install a step-up transformer in the power supply in order to
increase the voltage.
Note! Motor windings must be adaptable to this higher
voltage. Otherwise the motor must be changed. To give the
best possible advantage, the step-up transformer should
preferably be located close to the jobsite distribution board..
5.
Use some sort of soft start equipment.
