The WR series has been designed and built to lift loads from 1000 up to 5000 kg in heavy work environments, where great strength, and above all great reliability must be proven in order to maintain the highest performance for as long as possible.
These characteristics are demonstrated by the structure of the hoist entirely made of aluminum alloy and with the total absence of plastic material.
The lift motor
The engine is built according to FEM 2m class. Hoists can be supplied for any voltage upon request. Degree of protection is IP54. The machine must work in a covered environment free of vapors; for different environments or outdoor service please ask to the company. The 3000/4000/5000 hoists can be equipped with an engine cooling fan which, together with the finned structure of the motor housing, allows an excellent heat dissipation
The load limiter clutch
The WR series features electric limit switches that limit the maximum stroke upward and downward. There is also a safety device that acts as a limiter for overloads.
This is considered as an emergency stop and therefore it should NOT be used regularly.
The reducer is composed of helical toothed gears, this allows a progressive distribution of the forces on the tooth, at the same time a reduced operating noise. These components have undergone heat treatments to ensure high mechanical and wear resistance. With the recommended lubricants, the hoist is able to operate in environments with temperatures between -20 ° C and + 50 ° C.
