Optimised travel contour |
Space-saving drive solution ready for installation
Demag Cranes & Components has extended its range of industrial drive products with a new travel unit combination. The complete drive solution consisting of a RAE wheel set and an angular geared motor can be used wherever an optimised travel contour is required. It is designed to be used mainly on portal and semi-portal cranes as well as for travel applications in the general mechanical engineering sector.
The 400, 500 and 630 series wheel sets have a load capacity of 28 – 60 t per wheel and have played an important role in the Demag wheel product range for some time. A new shaft has now been standardised for installation on angular gearboxes. The proven shaft and hub connection is optimised for reversing operation as well as for all travel applications. The splined profile is designed to DIN 5480. The ARM 2 torque bracket is a new standard design that makes it possible to install angular geared motors in four different mounting positions. The ARM 2 torque bracket is fitted direct to the customer’s travel unit.
Angular geared motors in the upper performance range W 70 to W 100 with output torques of 2,500 to 12,000 Nm are used for the new travel unit combination. Demag Cranes & Components offers these units – as required – as cylindrical-rotor and conical-rotor brake motors for line or inverter-fed operation.
The new travel unit saves space and offers an optimised travel contour width. For a combination consisting of an angular geared motor with gearbox size W 70 (2,500 Nm) and an RAE 500 wheel set, the clearance width is reduced by some 60 percent compared to solutions with an offset geared motor. If two driven wheel sets are arranged opposite each other, this value further increases correspondingly.
The travel units can be installed in hollow profile sections and box girder sections. If preferred, a corner-bearing design is also possible. This makes it possible to benefit from the advantages of the Demag modular drive range with its matching components. The wheel sets are pre-assembled and can be supplied on site as a complete unit. They can then be fitted in prepared travel units without the need for any complicated alignment.
