Hoisting Equipment Manufacturer,Supplier and Exporter in India
Product Code : EL-WT-8795
Jlab Export is a leading Hoisting Equipment Manufacturer,and suppliers in India
This electric chain hoist lifts loads on a calibrated load chain of heat-treated Grade 80 alloy steel. Its crane duty motor is a squirrel cage type with a conical rotor, Class F insulation and a 1 hour rating. An electromechanical conical disc brake holds the load when the hoist stops, and the control circuit works at 110 V.

Workshop Exercises for Fitters and Electricians
Fitter and millwright trainees practise slinging a motor or a gearbox and lifting it onto a bench. The load chain hangs vertical and the load stays balanced under the hook. Before each lift they look along the chain for twisted, nicked or stretched links. They also measure the pitch over a few links with a Vernier Caliper and compare it with the wear limit for the chain.
Electrician trainees trace the 110 V control circuit. With the supply isolated, they check the motor windings with the Insulation Tester and test the control wiring for continuity with a Digital Multimeter.
Frequently Asked Questions
What does a conical rotor motor do?
In a conical rotor motor the rotor and stator are tapered. Switching on pulls the rotor along its axis by magnetic force, and in hoists this movement is commonly used to free the brake. When the power goes off, a spring returns the rotor and the brake is applied again.
What does Class F insulation mean?
It is the thermal class of the insulation on the motor windings. Class F allows a higher winding temperature than Class B or Class E, which gives the motor more margin when a hoist starts and stops often.
What does the 1 hour rating mean?
The motor is rated to run at its rated load for up to one hour at a stretch before it needs to cool. That suits hoisting, where lifts are short and spread through the day. Avoid long continuous runs beyond the rating.
Why is the load chain Grade 80 alloy steel?
Grade 80 is a strength grade of heat-treated alloy steel chain used for lifting. Calibrated links are made to an exact pitch, so they seat in the pockets of the load wheel. Check the chain often for wear, stretch and damage.
