Hoist Block Spring Interact with Limit Switch
Hoist Block Spring Interact with Limit Switch
(OP)
My company has purchased a trolley w/ 5t hoist and we've come to find out we need to raise the load an additional 6 inches. Raising the hoist/trolley assembly is not an option.
It has been suggested by our craning guys, just remove the 6 inch free length spring that encapsulates the chain just above the hook block.
Normally this spring would contact a lever arm that actuates a plunger type limit switch for upper travel.
How would the removal of this spring affect operation of the hoist? The spring is fairly stiff so I don't see it providing any critical dampening affect on the switch or the load. Any help would be appreciated.
