When specifying a hoist for use in industrial applications that demand beam-traversing motion, attention should also be paid to the trolley on to which the hoist hooks.
According to hoist solutions manufacturer JD Neuhaus (JDN), factors such as carrying capacity, ease of installation, explosion protection and ability to negotiate curves must all be considered to optimise the installation.
Three versions are available to facilitate the lateral motion of suspended loads: manual trolleys (LN) for pushing or pulling by hand; reel chain trolleys (LH) for moving by unwinding the reel chain; and motorised trolleys (LM) powered by an air motor.
While the standard industrial series stops at a single 20-tonne trolley, higher capacities can be achieved with the benefit of eight- and even 16-wheel systems. Custom designs or utilisation of the monorail series offer traversable load placement for the entire JDN catalogue of capacities up to 100 tonnes.
All JDN trolleys offer explosion protection to Ex II 2 GD IIA T4/II 3 GD IIB T4 classifications, with higher classifications available on request.
