Standardising hoist & crane control
J D Neuhaus (JDN) has developed a robust new concept for controlling hoists and cranes. The company’s JDN-RC (Radio Control) receiver is designed for long-lasting performance in rigorous operating environments commonly found in industrial and offshore applications, including ATEX (explosive atmosphere) zone 2/22 conditions.
Featuring a solid and extremely compact receiver (w = 250 mm, d = 120 mm, h = 200 mm) to suit even hoists with low-carrying capacity, all components are accommodated in a shock-resistant GRP casing offering protection class IP65. This means that the device is totally protected against the ingress of dust, and can withstand low-pressure water jets from any direction, thus making it resistant to seawater in offshore applications. Breathable membranes are deployed to help guide any condensation from the interior to the exterior.
The device facilitates quick and straightforward installation. This is largely because the JDN-RC has been developed to help standardise hoist and crane control. As a result, the receiver can be mounted on the hoist or trolley, or at a separate location, in line with specific customer requirements. What’s more, the standardised interface on the JDN-RC means it can be offered as a retrofit solution for JDN’s existing product range.
At the transmitter, single or two-step commands are supported by control elements that include a key switch, start and stop buttons, joystick, LED operating status display and LED low-voltage indicator. The JDN-RC control allows users to work at a safe distance from the load and take a better viewpoint during operations.
