excessive force to lift the load,
check for the following and resolve
them before continuing:
— Is the load heavier than the rated
capacity of the hoist?
— Are the chains or load entangled in
any way?
— Is an obstacle blocking the load or
chains?
— Are the chains and load not directly
under the hoist?
— Have the gears inside the hoist
housing jammed?
