How to use W4/W5 Chain Block
1. Judge the weight of the load to be lifted and make sure that the
weight Is not over the rated capacity of the chain block Never overload
the block on any occasion.
2. 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.
3. Before lifting, inspect the hooks to see whether they are securely
attached Obliquity of the hooks and load suspension at hook tip are
not permissible. For perfect performance of the block, the load chain
should be kept vertically straight without any twist so as to prevent it
from tangling.
4. During operation, the operator should stand in the plane of the hand
wheel. To lift the load , pull the hand chain to rotate the hand wheel
in clockwise direction ,When pulling the hand chain in the reverse
direction the hand wheel will be separated from brake seat, the ratchet
disc checked by pawl will be released, and the load will be lowered
down smoothly. Do not pull the hand chain In a position oblique to
the plane of the hand wheel to prevent tangling of the hand chain
and turning of the block.
5. For the sake of safety passing or working under a lifting load is strictly
forbidden.
6. While lifting or lowering a load the hand chain should be pulled
steadily so as to prevent It from jerking or tangling.
7. Stop operation immediately in case the hand chain cannot be pulled
any further, Don’t ask more hands for pulling, Proceed Inspection as
follows:
• If there is anything entangled with the load.
• Whether there is any trouble with the parts of the block.
• Whether the load weight Is over the rated capacity of the block.
