Elesa is promoting its range of arm handwheels, such as the Elesa VB range and the Elesa ETK/EYK series, which are generally used where greater leverage is required, either because it allows greater force or greater delicacy and accuracy. They are often employed in the setting or operation of machines, valves, actuators, clamping or in rotational devices that require manual operation. They are frequently used in conjunction with digital position indicators, where an electronic control system would simply over-engineer, over-complicate or over-price the application.
Elesa's VB198 moulded four-arm handwheel, at 170mm diameter, is suitable for fine single-handed control or two-handed operation; alternatively, the VBR.4 features tubular metal handles and is available in diameters from 200mm to 363mm. The VBR.2 matches the .4 but with two arms for lower cost. Three-arm handwheels with revolving handles from the ETK and EYK series are suitable for steering applications and have central hub colour indexing options – the ETK featuring straight revolving handles and the EYK having palm-fitting revolving knobs for applications requiring faster operation.
