The new U trolley generation is available in two sizes for load capacities up to 1100 kg (U 11) and 2200 kg (U 22). The flange width can be infinitely adjusted by means of two adjusting rings and covers the ranges from 58 mm to 200 mm, and 201 mm to 310 mm.
This facilitates fast and simple installation. The travel rollers, which are made of high-strength and wear-resistant Polyamide, provide for smooth operating characteristics and low travel resistance. Optional steel rollers can also be used for special ambient conditions, e.g. high temperatures.
The universal design of the travel rollers enables them to be used for operation on straight and sloping profile sections. The lateral steel guide rollers support their curve-negotiating properties down to the minimum radius of 1000 mm and minimise girder wear. A drop-stop arrangement is integrated into the side cheeks, which consist of aluminium die-castings with a powder-coated finish.
Push-travel U trolleys are designed for simple addition of the E electric travel drive at a later date.
