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.

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. 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.

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.

Electrical control panel
The panel is fully hard wired with all components mounted on a steel backing plate. The panel includes high quality contactor switches, a transformer for low voltage (24V) controls, brake
rectifier, fuses and connector terminals. Thanks to these high quality components, up to 240 operations
per hour can be carried out. The electrical control panel is mounted in an IP65 plastic enclosure and follows the CEI-EN 60204 norms. In addition, the panel are fully compatible and interchangeable with a full range of hoist models.

Guide chain
The hoists central body and patented chain guide are machined from one single casting, this allows precise possitioning of the load chain into the load sprocket.
