INSTRUCTIONS
FOR USE
The Brake Pulley has been designed and manufactured to be used at height. It
implements a breaking mechanism which ensures that if the load is released under
any circumstance it descends to the ground, but in a controlled manner. Descent
speed can be pre-determined by gearing, brake liner, brake shoe or combination
thereof.
GENERAL USE:
• Do not install or use this brake pulley in a dierent way from what this manual
species. Manufacturer is not responsible for any damage due to poor use or
neglecting the safety measures.
• The work area must respond to the safety requirements by law. In particular it is
forbidden for persons to operate below the suspended loads.
• Do not use brake pulley for lifting loads or heights exceeding the values specied
in the product specication.
• Do not use ropes with diameters dierent from ones stated in specication.
• Do not use ropes with the diameter reduced by wear below the minimum diameter
stated, or if strands are deformed or damaged. The malfunctioning of the pulley
due to use with a damaged rope is the responsibility of the user.
• Before use, check the correct positioning of the pulley on the scaold and test the
braking eciency related to the working height and rope weight.
• When using the brake pulley personal protective equipment must be used. Safety
gloves additionally should be used.
• Store product in a dry and clean environment after use, if any dirt or dust present it
must be cleaned, preferably by compressed air.
• This device must only be serviced by a trained and competent individual. Never
attempt to service this unit or tamper with its function in anyway.
• Do not remove, or substitute any spare parts of the pulley with non-original parts

OPERATION
BEFORE USE:
• Inspect work area ensuring it is free from any obstructions that may prevent the
safe use of the device.
• Safety equipment must always be used when operating this product e.g safety
boots, gloves and hard hat.
• Two competent operators must always be present, one on the ground and one at
the working level.
• Ensure the rope it is inserted in the correct direction as seen gure 1
Figure 1- Direction of rope inserted into braked pulley
WARNING - BEFORE USING THE BRAKED PULLEY IT IS COMPULSORY TO:-
• Check the brake eciency, does pawl engage when load is dropped and speed is
exceeded.
• Check the free rotation of the swivel attachment onto the pipe
• Check the free rotation of the rope pulleys.
• Check to ensure all xings are secure and have not been damaged or tampered
with.
• Check the condition of rope- any signs of damage from heat, sharp objects, and
chemicals. If in doubt replace the rope.
NOTE - If the braked pulley does not pass with any of these points then it
should be placed in quarantine for service by a trained and competent person.
MAX 50KG

OPERATION
FITTING THE BRAKE PULLEY
• Carry out pre-use inspection of the environment before attaching device.
• The attachment point must be a standard pipe for scaolds, with external
diameter 48 mm.
• The attachment of the pulley is xed at the extremity of the pipe and locked
against the longitudinal movements by two clamps, one per side of the brake
pulley.
USING THE PRODUCT:
Lifting the Load
• After the routine checks rmly secure the load and start pulling the rope lifting the
load to the desired level.
•
• During this process if the rope is suddenly released, the load starts a small
descent and immediately afterwards the brake is automatically engaged and load
descends to the ground in a controlled manner.
•
• This controlled descent speed allows the user to re- gain control of the load safely,
and can be done using one hand.
•
• Always lift a load which is adequate to the physical capacity of the operator, also
related to the lifting height.
•
• To ensure maximum safety of the operator at ground when lifting loads, they must
stand as far as possible from the load descent area.
Lowering the Load
The same outcome applies when the load is lowered from the work height. If the
rope is released when lowered the brake also activates descending the load in a
controlled manner.

INSPECTION
AND MAINTENANCE
INSPECTION
VISUAL INSPECTION SHOULD BE CARRIED OUT REGULARILY
This device and all equipment must be visually inspected by a competent individual
when delivered to site also thoroughly inspected before and after every use.
ROPE - Examine for cuts, cracks, tears, abrasion* and scorch marks, burns or
chemical attack.
DRUM / RATCHET - Pull on rope sharply to determine if pawl engages to activate
brake mechanism.
METAL WARE – Inspect for signs of damage, distortion or corrosion as well as
ensuring correct operation.
LABELLING - Check that all information included is legible.
* Common abrasion wear within rope may be caused by passage over sharp edges when under tension
which may result in serious loss of strength. Slight damage to the outer bres could be considered
harmless; however serious damage such as reduction of diameter should lead to rejection and be
immediately removed from service.
ROUTINE INSPECTIONS
It is recommended that, in addition to the above, the unit is subjected to a thorough
routine inspection at least every 6 months.
A record card is contained with this manual and should be lled after each routine
inspection.
• Thorough inspection is to be given to each of the following:
• Check the unit is clear of any debris and the rope is running freely
• Check the rope is in good condition, clean and free of contaminants.
• Damaged or contaminated rope should be discarded
• Check the pulley is rotating freely smoothly in both directions
• Check that speed of descent is acceptable.
(e.g. 25kg load approximately 1.5m / sec)
• (If the lowering speed is too fast change the brake cartridge)
• Check the brake linings

INSPECTION
AND MAINTENANCE
MAINTENANCE: (No special training is required)
This product requires minimal ongoing maintenance apart from visual checks and
general housekeeping, cleaning and the occasional simple replacement of the brake
cartridge.
Hand wash using hot water and mild detergent (NO chemicals) then rinse with clean
water allow drying naturally with rope exposed.
The only wearing part is the brake shoes which cannot catastrophically fail and are
proven for minimum 100,000m use under 25kg load. (Excessive wear would simply
result in an increasing descent speed, which can be noticed and rectied before it
becomes an issue).
The Brake shoes should be changed annually or sooner if excessive use requires.
The brake shoes are assembled on a cartridge which can be simply changed in only
2 - 3 minutes, by any able person using a standard hex drive for removing 8 screws.

bigbensafety.com
CHANGING THE BRAKE CARTRIDGE
Simply undo the 8 screws on the front cover of the brake drum, withdraw the brake
cartridge, check the inside of the drum is free from any contaminants and simply
plug a new cartridge. ( it will automatically align to the correct position ).
The Cartridge is readily available either on a replacement or exchange basis from
approved dealers and being compact and lightweight it can be mailed to any site
location globally.
Annual Inspection and service by an approved service centre is also recommended.
If any part of the product is found to be defective, please complete below section
stating all defects and remove from service immediately.
