Chain Hoist Load Limiters

LLL-C on Chain
Installs Quickly in new or retrofit overhead wire rope / chain hoists or winches. No special tools required. Simply attach to the dead end (stationary) part of the hoist rope or chain and bring the electrical cable up to the control to drop out the “UP” contactor or other signal to control the hoist (such as to a Power Electronics MICRO-SPEED® hoist variable speed drive). The hoist can now only be lowered until the “overloaded”  ondition is corrected.

Rugged Design - Manufactured from high tensile aircraft type aluminum, they are very compact. A heavy duty micro-limit switch is used for the mechanical overload trip. The overload setting is easily adjusted on the back. A protective removable housing contains the load limit adjustment in the field. The housing is powder coated and electrostatically applied to 50-75 microns oven cured at 200 degrees centigrade for 20 minutes to obtain high anti-corrosion resistance and durability. Seven models to choose from for use on small hoists all the way to 250 tons or more. Pre-set available.

Repeatable Set - These devices can be factory PRESET or set in the field using known weights. Repeatability is within 2-5% of maximum load setting in most cases.
