The tight design and position tolerances of the housing and corresponding precise geometry in all planes, ensure that our wheel blocks can be easily fitted to your installation, with starting and braking characteristics which are gentle on the runway. In addition, special stiffeners guarantee high rigidity.
Simple Wheel Replacement be completed using conventional tools. The patented asymmetrical housing configuration allows for removal of the wheel without the need to remove and re-align the complete wheel block assembly.
The housing, enclosed on five sides, protects the travel wheels from external mechanical influence. The housing is high quality, corrosion-resistant, die-cast aluminum with a powder coating up to 90 mm thick.
The new Demag DRS wheel block system features numerous new and/or patented design solutions such as the torque bracket, the travel wheel bearing arrangement, the travel wheel hub connection, the sliding nuts in the top connection, and also the housing design.
The travel wheels feature generously dimensioned grooved ball bearings which are lubricated for life. Arranged inside the housing, the bearings have optimum protection against mechanical influences.
To eliminate any problems in aligning wheel blocks, Demag has developed a laser alignment system. Together with prepared brackets on the housing and eccentric pins which fit in slots in the top of the wheel block, this system makes it possible to align wheel blocks mounted on multiple trolleys rapidly and exactly in line with each other.
Of particularly compact design, our new wheel blocks feature high ground clearance. This also applies to the complete drive units with the gearbox concept designed to match the wheel load.
A new flange wear indicator shows when the travel wheel has to be replaced. This helps to guarantee reliable operation and prevents down-time.
