DRSA 250 to 500 Wheel Block System Manufacturer
DRSA 250 to 500 wheel block system made in China, suitable for loads up to 40,000 kg, is designed as a heavy-duty travel unit based on the same principle as the smaller 112 – 200 series. The advantages of the system are:
•Most favourable ground clearance conditions with Demag offset geared motors.
•A robust spheroidal graphite cast iron housing with precisely machined connect- ing surfaces.
•Variable basic design by fitting various travel wheel materials and shapes.
•Possible compensation of track gauge deviations up to 4 mm or skewing up to 14 ‰.
•Protected internal bearing arrangement featuring tapered-roller.
•Minimum maintenance due to bearings lubricated for life.
•The anti-friction bearing arrangement is prepared for re-lubrication and re-lubri- cation sets can be simply added later on.
•Travel wheel and bearings can be replaced thanks to bolted housing, without the housing having to be removed.
•High installation availability since the housing does not necessarily need to be removed to replace the travel wheel. Not having to realign the housing saves time.
•The torque bracket, designed to match the wheel block, reduces peak loads which occur as a result of the travel wheel slipping torque.
•High-tensile bolted connections are galvanized and therefore provided with a special surface protection. Residual flange indicator enables preventive maintenance without risk to the installation.
