BEFORE LIFTING
1. Careful inspection should be made to the parts, such as hooks, load chain,
braking device, etc. and the lubrication of the block. The chain block can
only be put Into operation when It is found to be in good condition.
2. Judge the weight of the load to be lifted and make sure the chain block is
suitably rated.
• Never overload the block on any occasion.
3. Attach the chain block to the suspension point.
• The suspension point must be able to support the weight of the load and
the chain block.
4. Attach the load hook directly to the load or sling, ensuring it is directly
above the centre of gravity of the load.
OPERATION
1. Ensure that no obstruction prevents a clean lift
2. Gently raise or lower the load by pulling the hand chain through the block
in the desired direction - Clockwise to lift and anti-clockwise to lower
• While lifting or lowering a load, the hand chain should be pulled steadily
so as to prevent it from jerking or tangling.
• Lift the load a few centimeters and check stability before commencing
full lift.
• DO NOT allow anyone to walk or work under a lifting load.
• You should look for any defects occurring during operation and stop
using the chain block if you notice any.
• When lowering a load, be aware that when the hand chain is released,
the load will not stop immediately, but may continue for a few more
millimeters as the brake takes effect.
NOTE: The brake may get hot with continued use.
3. After operation, clean the chain block and lubricate the chain if required.
Store it in a dry place to protect it from rust and corrosion.
