Motorised trolley units for use with hoists
August 1st 2004

New motor operated trolley units have been developed by JD Neuhaus for use with its Profi TS range of air operated hoists. Fully pneumatic operation and different levels of spark prevention mean the equipment is suitable for up to group 11C explosion protection (EX 112 GD 11C T4). The trolleys feature a compact design that requires low headroom to make the best use of space and streamline materials handling operations. Easy to install, service and maintain, they can be fitted to beams with a boom flange thickness up to 40mm. Flange widths from 50 to 300mm can be accommodated, with accurate adjustment provided by a threaded clevis pin, which is secured with lock nuts. New, low noise level drive motors with two step are featured as standard. These have lube free operation, eliminating the need for an additional filter silencer. The Profi TS hoist used with the trolley is available in four lift capacities from 0.25 to 2 tonnes and also features twin speed motors. They are top hook suspended and twist secured as standard. Braking is provided by two independent systems for maximum safety. Lifting and lowering speeds are infinitely variable over the operating ranges with an input air pressure of 6 bar.
