PREFACE

Dear Customer,

Jinlong Europe, a revolutionary evolution!

Reliability, quality, safety, and high technology are the success of Yongmaos

topless tower cranes all over the world.

In Europe all our cranes are CE approved. This is the result of a constanttechnological research.

The absence of tie-bars allows an optimized erection (quicker and safer).

The use of small sized mobile cranes saves air space. The best solution for

installation in job sites next to airports or in the city with several cranes in use and

interfering working areas.

Because of our relentless efforts to improve our products, technical updates are

from time to time necessary. Therefore, the technical data in this manual are subjectto change without warning.

Topless tower cranes, a revolutionary evolution.

1.3.3. DIMENSIONAL FEATURES OF THE FOUNDATIONANCHORS

The foundation anchors are placed symmetrically in the foundation blockand are to form a 2-by-2 m square, based on the dimensions of the mast to

be erected (see Fig. 1.3.3.-1).

The distance between the topside of the mounting plate and the topside of

the foundation block must be 150 mm.

ATTENTION: Cutting or reducing the reinforcement in the

foundation is prohibited.

1.3.4. INSTALLING THE FOUNDATION ANCHORS

The foundation anchors are mounted by means of:

4 foundation anchors and 8 associated pins

1 foundation framework and 8 associatedpins 1 standard mast section

1plumb line or measuring device

- Check the framework for any deformation during transport. The

difference between respectively the diagonals and the bearing

surface heights may be at the most 2 mm.

- Install the foundation anchor on the reinforcement and adjust by

means of filling plates.

- Check perpendicularity in both directions after assembly of the

lower mast section on the framework. Adjust if necessary.

- Pour the concrete block and wait until it is completely hardened

before removing the mast section and the framework

1.5. COUNTER-JIB BALLAST1.5.1. INTRODUCTION

The counter-jib ballast consists of various reinforced concrete blocks A,B or C. The counter-jib ballast is governed by the length of the jib. These

blocks are suspended one by one at the rear of the counter-jib.

The ballast is to be supplied by the client in accordance with Fig. 1.5.2-1.

During installation, care must be taken to ensure that they cannot be

chipped or become loose while operating the crane.

Composition and structural dimensions are dealt with in point 5.2.

The admissible tolerance is 500+

kgper block.To allow for concrete density

changes, alter dimension X to bring the blocks within the indicated

tolerance.

We recommend weighing the concrete blocks and marking their weight

with paint on a visible side of the block.

- The electrodynamics brake inductor is supplied withdirect current.

- An amperage change in the inductor produces a speedchange. In that way, the desired speed can be obtained

by means of the control box.

At Standstill:

- The power supply to the motor is switched off, poweris supplied to the inductor of the electrodynamics

brake and the jib is brought to a stop;

- The safety brake only locks when, in case of necessity,the operator presses the slewing brake button (XRFS).

ATTENTION: Stopping the jib by counter-slewing is prohibited.

At the end of the workday, the jib must be placed inweathervaning.

4.2. COMPOSITION OF THE TROLLEY WINCH UNIT

The DTC trolley winch unit consists of the following components (seeFig. 6.2-1):

- Rope drum- Gearbox- Electric squirrel-cage motor- Electromagnetic brake- Disk brake

Three speeds are available:

MV: Low speed, realized by a combination of actuation of the

electromagnetic brake and running of the motor at lower voltage

(230 -260 V).

PV1: Medium speed, realized by partial actuation of theelectromagnetic brake and control of the motor voltage (380 V).

PV2: High speed; the motor is run at its rated voltage (380 V) without

excitation of the electromagnetic brake.

The disk brake of the trolley winch unit is of the regular closed type (i.e.release through voltage control).

Normal brake clearance is 0,8 1,2 mm.

The brake clearance is set in an identical way as for the slewing motor.The brake torque is set by a spring screw Fig. 4.2-1 item 14.

4.3. TROLLEY BRAKE

4.3.1. Description (SEE FIG. 6.3.1-1):The electromagnetic brake starts operating as soon as the power supply is

cut. Brake clearance in the active range is automatically adjusted.

1. Operating principle

Fig. 6.3.1-1

Brakes:

When the current is cut, the electromagnetic attractive force disappears.The brake spring (2) pushes the pressure disc (6) back on the brake disc(5). This closes the brake. The brake is of the regular, closed type.

Releasing the brake:

When the excitation coils (1) is energized, the pressure disc (6) isattracted and the brake pressure spring (2) is pressed in. By this, the brakediscs open up.

Brake clearance:

Normal brake clearance is 0.8 to 1.2 mm. Check the brake clearance for

soiling (oil - grease).

Brake moment adjustment:

The brake moment was factory-set

Releasing the brake manually:The brake can be released manually by loosening the brake yoke (3).

PROGRAMMED MAINTENANCE

- Every 200 hours or once a month:

- Check brake clearance and brake moment, as well as the condition

of the brake discs. Brake clearance is to be 0.8 1.2 mm.

- Attention: replace brake discs before they are completely worn.

- Check if there is any foreign matter in the brake and if it is free

from oil and grease.

ATTENTION: The brake must immediately be inspected if:

- It does not work properly- It is overheating- Abnormal vibrations are noticed- Braking torque is insufficient
