WR series hoists are designed to lift loads from 1000 kg to 5000 kg in a production environment with a high duty cycle and proven reliability. The hoist body is completely manufactured from aluminium and steel with no plastic components.

RWM WR series hoists are supplied with upper and lower electric limit switches to prevent hook over travel and prevent the use the clutch as an ultimate limit and extending the life of the clutch and gearbox.

The hoists are also equipped with a slipping clutch that is set to 120% of the working load limit to prevent accidental overloading.

Electric motor
The three phase motor is produced with single or double windingsfor single or dual speeds. The insulation is class F for both motors. Manufactured to FEM standard 2m, the WR hoists have a duty of 55% on single speed hoists and 15+40% on dual speed hoists. Standard operating voltage's 230/400V, 3 phase, 50 Hz, other voltages available on request. Hoist motor protected to IP 55 against ingress of dust and water, upgradeable to IP 65 upon request. The hoists 3000/4000/5000 have a standard fan assisted motor for better cooling and increased duty cycles.

Reduction gear
The reduction gears are designed in such a way that the speed of the hoist can be changed simply by increasing or decreasing the number of components in the gearbox. The gears are manufactured from high tensile steel and are hardened and heat treated to give maximum life. With the correct choice of oil the hoist can work within the following temperature
range, -20°C to +60°C.

The Hoist brake is a 400 V AC electro magnetic brake type. The advantages of this 400v three phase brake are, high braking power, very strong structure and no transformer, the brake is manufactured from aluminium die-casting for good heat dissipation, the brake coil is fully encased in epoxy resin. The brake disk is manufactured from asbestos free material.
