Identify and know the functions of all the safety devices on a winder and in a shaft and headgear.Know the devices in a headgear separate from that on a winder.

All safety devices should be, where possible, inspected visually as to be able to identify it properly.

45

OVERWIND SAFETY DEVICES ON A WINDER

Lilly controller

Description. Each winder drum is fitted with a separate lily controller It is enclosed in a metal or fibre box. The old type can be recognised by copper balls attached to it. The lily is a controller and not a device Consist of 13 different safety devices.

Functions.The basic functions of the Lily controller are.

Over speed control. Upper and lower overwind. Wrong direction warning device (Philips) Three turn warning device

Overspeed controlManagement set a certain speed of travelling for the conveyance in metre per

second. In the case where this set speed is acceded the lily will cause the winder to trip

Upper and lower end of windOverwind is when the conveyance go past the upper and/or lower end of wind

which is about 1,5 metre above the bank (men overwind) and below the lowest landing. In the case of a skip compartment the overwind trips are set above the tip and below the main loading boxes

Wrong directionThis is when the conveyance move into the wrong direction from the bank

(up). The Philips device will sound a warning to the driver as to prevent him from moving into the overwind

Three turn warning deviceThis device warns the driver that the conveyance is three turns of the drum

below the bank and he must be alert.

Over speed Retardation and Acceleration

The lily controls the speed of the winder as set by the Engineer depending on the condition of the shaft. This differs between 10 and 15 while doing normal transport

The lily also slow down the speed of the conveyance when approaching the bank called retardation.

When the driver pull away too fast from standing position the winder will trip this is called acceleration.

46

1. Cam gear overwind

It is a mechanical device It works separately from the lily device Each drum has its own device

Function In the case where the lily fails the camgear will trip the winder on

overwind

2. Bell-brake interlock Dickson device

Operates in conjunction with the lock-bell system and the winder brakes

Function. If the driver signal to the onsetter the device is activated and locks the brake. If the onsetter signal to the driver the brakes are unlocked If the driver signal to the banks man the device is activated and lock the brakes. If the banks man signal to the driver the brakes unlock. Note>the brakes will only unlock after signals has been given from both the bank

man and the onsetter.

The phrase “the brakes lock” means that the driver can not release the brakes and put the winding engine in motion. See the picture

3. Philips device.

Directly operated by the lilly device.

Function. When the winding engine driver moves the conveyance in the wrong direction, from

standing position on the bank, towards the upper or lower overwind, this device will sound a warning to the driver.

4. Clutch/Brake interlocking system.

It is a mechanical device coupled to the clutch and brakes of a winder drum.

Function. It prevents the releasing of the brakes on the un-clutched drum while clutching is in

progress.

5. Clutch locking pin

Consist of a steel pin, when the winder drum is unclutched, the pin automatically fits into a hole in the side of the winder drum. In the case where the pin does not enter the hole correctly, the drum will not unclutch.

47

Function It prevents the un-clutched drum from turning

6. Slack rope device.Consist of a 12mm galvanised steel wire rope underneath the winder rope, connected to a bell and trip switch.

Function. In the event of slack rope the rope will come to rest on the wire rope it will sound an

alarm and trip the winder.

Slack rope is caused when the conveyance got stuck in the shaft and the drum is still turning and unwinding rope. The rope will then coil on top of the conveyance and might coil into other compartments as well.

This slack rope device do not always operate due to the weight of theconveyance and the rope that keeps the winder rope tight and prevents it from coming to rest on the wire rope

Two different electronic slack rope devices are in use at the moment:

a) Situated in the sheave wheels and when the conveyance get stuck, the weight is released from the wheel and this trips the winder

b) In conjunction with the humble hook. When the conveyance get stuck and the slack in the rope cause the humble hook to tilt this device will trip the winder

7. Backing out switch

Electrical switch operated by the driver’s foot.

Function Enable the driver to back the conveyance out of the over-wind.

8. Bad coiling device

Situated below the drum

Function Trip out the winder in case of bad coiling, that is when the rope

climbs over the previous coil of rope.

Safety devices controlling an overwind in a shaft

Although the bottom overwind, 3 turn warning device, men and material overwind come into operation while the conveyance travel in the shaft it can not been seen because it is coupled to the lily.

1. Bottom overwind trip

Directly coupled to the lily

Function It will trip the winder, when going past a set mark below the lowest landing.

Mainly when travelling single drum doing shaft exam, after a shaft accident, and also while clutching is in progress

2. Three turn warning device.

Part of the lily device.

Function. When the conveyance is three turns of the winder drum below the bank an alarm

will be set off, which warns the driver that the conveyance is approaching the bank.

3. Men over wind.

Directly coupled to the lily

Function Trip the winder on top overwind +- 1.5 metre above the bank

4. Material overwindWhen going over to material, the onsetter and banksman signal 8 to driver, the driver will turn a switch over from men to material.

This will cause the following:a) Overwind trip is set higherb) The 10 seconds delay is cancelledc) Driver can only give signal 1

d) In some cases the speed is set higher

Overwind trip set higher: The men overwind will be cancelled and the material overwind

trip will come in operation. This trip will be high enough for long material to be slung from

the bank into the shaft. A rail bogey is normally the longest material to be slung

The men and material overwind consist of one trip only, situated in the lily. When the switch is on material the men overwind is cancelled and when on men the material overwind is cancelled

The 10 second delay is cancelled: In the case where the person giving signals want to travel with

the conveyance there is a 10 seconds delay set in which the driver can not release the brakes of the winder.

This 10 seconds delay is to allow, the person giving signals, after the travelling signal 1 or 2 was given, remove the key, get into

49

the compartment and close the shaft gate, get into the conveyance and close the conveyance door

When doing material this 10 seconds delay is cancelled to save time. If the 10 seconds still remain it means that the driver will have to wait 10 seconds, after receiving a signal 4 pause 1 or 4 pause 2, before he can move the conveyance

Driver can only signal 1: The reason why the driver can only give a signal 1 is to prevent

him to, by mistake, allow the person giving signals to travel with the conveyance when there is no 10 seconds delay for him to get into the conveyance

5. Over speed Retardation and Acceleration

The lily controls the speed of the winder as set by the Engineer depending on the condition of the shaft. This differs, the conveyance travel, between 10 and 15 metre per second while doing normal transport

The lily also slow down the speed of the conveyance when approaching the bank called retardation.

When the driver pull away too fast from standing position the winder will trip this is called acceleration.

Mechanical Safety Devices in a headgear

The following mechanical overwind devices can be seen in the headgear

6. Magnetic switch.

Description. Installed between the material and ultimate trip. A magnet is mounted on the bridle. A magnet, with opposite poles is mounted on the steelwork next to the guide

connected to a switch with a electric cable leading to the winder. When the magnet go pass the switch the winder will trip

6.2 Function. In the event of an over wind where the other trips fail the magnets in the bridle activates the switch on the steelwork and trip the winder.

7. Ultimate switch. (Tarzan Wire)

7.1Description A galvanised steel rope, crossing the compartment, attached to a trip switch mounted

on the headgear steelwork. An electric cable attached to the switch leading to the winder.

7.2Function. In case of an over wind where the other trips fail the conveyance will strike the

galvanised rope. It will activate the switch and trip the winder.

50

8. Jack Catches.

8.1Description. It is mounted on the shaft steelwork below the crash-beams and striker plate. Consisting of 4 to 6 steel teeth. It is spring loaded i.e. when one tooth is pressed closed the other opens up. The bridle is slotted to allow for the jack catches teeth to form a ratchet.

8.2 Function. In the event of an over wind it allow the bridle to pass the catches. In the case of an overwind where the rope was detached from the humble hook and

the humble hook fails to arrest the conveyance the bridle will come to rest in the jack catches.

9. Spectacle plate. ( Striker plate)

Works in conjunction with the humble hook9.1Description. Consist of a steel plate installed on the crash beams above the jack catches,

between the catches and the sheave wheel.

The plate has a hole, through which the winder rope runs, large enough to allow the partial entrance of the humble hook

9.2 Function. In the case of an over wind, when all other devices fail, the humble hook goes

into the striker plate. The shoulders of the movable scissor strike the side of the hole in the plate,

shear the copper pin, the humble hook open up and release the rope. When gone through the plate, the arresting shoulders of the humble hook

open up and come to rest on the plate.

In the case where all other overwind safety devices fails, and the humble hook enter the spectacle plate, the banksman must signal accident to shaft on the call bell immediately and inform his superior.The Engineer will arrange for the conveyance to be supported by means of chain blocks and slings properly and for the persons to leave the conveyance.On most of the shafts there are a staircase and elevator available for this purpose

Stop blocks

There must be a plan posted up on all the landings showing the position of all workshops, refuge chamber, fire hydrants, escape ways, stop-blocks etc.

1. Shaft gates Steel frame with expanded metal Will not prevent rolling stock from falling down the shaft but will stop persons from

having unauthorised entry to conveyance or compartment that could cause them falling down the shaft

2. Double action Also called “Vula Vala” due to the fact that when the one end is opened the other

end close automatically and therefore one end is always in the closed position Can be operated by a handle consisting of a 50mm pipe

3.Vertical RSJ Consist of a 200x200mm RSJ fitting vertically into a concrete lined put

4. Farmgate Consist of a 200x200mm RSJ placed horizontally over each track leading to the

shaft Open and close similar to the gates used on farms It can be locked in the closed position to prevent unauthorised persons to open it The onsetter will be in possession of the key

5.T-Sprag

Consist of two sleepers bolted together in the shape of a cross

Also called Fly-machine sprag due to the construction of it. The T-sprag must be chained down to an eyebolt in the concrete floor

6. Shift control gate Although this is not installed to prevent rolling stock from falling down the shaft it

has other safety aspectsa) Control the shift, and prevent stampeding, as well as persons

crowding at the shaft and preventing the onsetter from doing his work.

b) This also enable the shift controller to count persons to be loaded per deck and not exceeding maximum load

7.Huisen device This is a very effective device not used on many shafts yet

65

It is spring-loaded and prevent cars from entering, but cars moving out will push it down and the spring forces it into position when the car has gone past

It can be operated by means of a compressed air cylinder It can be interlocked with the Dixon device and can only be opened when a signal

from the driver, which will lock the brakes, is received. It is also called “Sharkfin” due to it’s shape

8. Tank trap Two short rails bonded together that fits over a put These rails are placed in position while doing cars and removed when finished

9. Traverse pit (on the bank only) A put about 80cm deepx3m wide parallel to the full width of the shaft A traverse car is used to transport cars over the put.

10. Levelok

Not many are used at the Gold Fields mines

Steelwork mounted on the top of the bridle When the conveyance stop on the landing a hose is connected to it which

cause clamps to grip on the guides This prevent stretch in the rope while loading When loading is completed the hose is disconnected and the grip is released

Removing the slinging bogey on the station

Step 1

Preparations Open shaft screens above gates to allow space for when bogey is to

be removed from the shaft. Tie open screens down well.

Examine the following thoroughly for any defects.Small hoist brake, rope and attachments.Safety beltsFall arrestors.Track to be clear of cars as to be able to move bogey to behind stop blocks.Equipment and tools to be used

Step 2

When conveyance in vicinity Signal 1> stop conveyance when end of bogey level with landing Signal 8 to driver Driver repeat 8 (switch over from material to men to give the signal

and switch back to material) 1 from driver > persons may have access. Assistants to be secured by safety belts. 0pen gate and attach small hoist rope to bottom of bogey. (a short

sling will be left on bogey, make use of steel hook to get hold of sling) Gates to be secured to prevent it from getting in the way of the bogey Remove only stop blocks preventing bogey to be pulled out of the

shaft. Assistants to move to a safe place. Small hoist driver to tighten rope. Signal 4 pause 2 to driver > lower slowly. Simultaneously with the lowering of the bogey the small hoist driver

must pull the bogey out of the shaft. Ensure that when the wheels of the bogey are out of the shaft it is

placed correctly on the tracks of the landing

118

When bogey is completely out of the shaft and all its wheels are correctly on the tracks signal to small hoist driver to stop. He should then stop and apply the brakes.

Allow conveyance to lower slowly until slack on sling is sufficient to remove the shackle bolt.

Signal to driver 1 > stop when in motion. Driver repeat 1 > people may have access. Assistants to be secured by safety belts. Remove sling from bogey and attach it to the conveyance as per

standard. Close shaft gates. Remove stop blocks and move bogey to behind last stop block. Replace all stop blocks and lock where applicable Remove small hoist rope from bogey when applicable.

Lowering of material in cars (Banksman)

Daily conveyance exam

The boilermaker and fitter do a daily exam on all conveyances but it is also a duty of the banksman and onsetter to do a visually exam.

Safety devices in and on a cageTo be checked by the onsetter daily:

1) Main door with hinges and pins to keep it in position2) Small lockable door3) Drop bar4) Rail skid sprag attached to a chain to prevent it from hanging or falling down the shaft5) Rail track (check for obstacles that might cause a derailment6) Stop block at the back wall of the cage to prevent cars from bumping against the steel wall. Without a stop block the cars can cause the back wall of the cage to bend to the outside and it might strike against the shaft steelwork.7) Expanded metal vent ports8) General condition of the floor, roof and sides of the cage 9) Flap doors opening and closing properly10) Dolly wheels> rubber not torn etc.11) Humble hook >copper pin etc.12) Attachment between the humble hook and winder rope13) General condition of the bridal14) Cover attached to the loose (jobs) bridal closing properly.

Fixed bridles do not have a cover assembled to it and therefore no long material will be loaded through the flap door in the roof. The onsetter will not be able to remove the long material because there are no cover to prevent falling objects from injuring him and his assistants.15) Gap between the cage and landing not to be less than 50mm16) Apron properly suspended17) Slings underneath the conveyance, tied to the front at the apron 18) No loose rock or debris. If any it must be offloaded using a safety harness and the cover in the closed position.

Clutch for level cars should be lowered to Signal to driver 4 pause 4pause 4, station and bank signal and 2

pause 2> clutching signal. Driver will clutch for applicable station Driver should clutch so as to the conveyances can not be loaded on

the bank and offloaded on the station simultaneously. Normally he will clutch so that the conveyance will be below the bank while the other one is level with the station. That means the Onsetter will be able to offload first before the banksman can load the second lot.

This is done to prevent confusion in the case where both the onsetter and banksman load and offload and give 4 pause 2 and 4 pause 1 signals to get the conveyance level.
