RMW Electrical Chain Hoist

Lifting motor
The cylindrical parallel rotor is produced with single windings for single speed hoists or dual windings for dual speed hoists and all have class F insulation. Manufacture in accordance with FEM class 2m, the duty cycle for single speed hoists is 40% and 10 + 30% for dual speed hoists.

The supply voltage for these motors can be specified when ordering and they are available in a wide range of voltages, phases and hertz, thus making the RWM chain hoists again very versatile and capable of working in any environment. The braking system of the chain hoist uses a 230V spring-activated electro magnetic brake which allows for quick and safe stopping allowing the load to be held at any desired height or position. The chain hoist has an IP54 protection which protects it against dust, limited ingress and against low pressure jets of water from all directions, limited ingress, for standard indoor use. For other environments, please contact us.
Reduction gears
Found in the gear box’s are epicycloid, totally enclosed and lubricated with a permanent high performance grease. The gears are manufactured from high tensile steel and are hardened and heat treated for smooth operation and maximum life span. In addition, due to its sealed lubrication, the chain hoist can operate within a temperature range of -20°C to +60°C.
Overload by clutch
The slipping clutch is a safety device which limits both the up and down stroke of the chain hoist, by limiting a possible overload.It is constructed from asbestos free braking plates held under pressure by cup springs and is adjustable. Note: this is only a safety feature and should not be used as a working limit. The clutch is setting at 15% respect the nominal capacity of hoist.

The W-series range of electric chain hoists can be distinguished by the following; its extremely compact size giving the best possible closed headroom, its exceptional quality and its high levels of reliability. All are achieved by having the highest quality manufacturing standards, continuous improvements and quality control. All mechanical parts are examined under stringent condi- tions and rigorously tested.

W-series

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.

WR series

The low headroom trolleys are used when it is necessary to have the maximum utility height between the floor and the beam. It is important when we have buildings with low height or when it is necessary to enter in compact spaces.

The low headroom

RWM power travel trolley's can be fitted to all models of RWM hoists and are used when the load needs to be traversed laterally along a beam. They are fabricated with heavy duty side plates and fitted with anti-drop plates.

They have precision machined steel wheels running on permanently sealed for life bearings, braked motors and have travel limits fitted as standard to prevent the hoist being run into the beam end stops, preventing damage.
