1.2 Travel Wheel Materials
40Cr
The DRS112~DRS200 utilizes 40Cr hot-rolled round steel, treated through a meticulous quenching and tempering process for enhanced durability.
Our advanced material selection ensures optimal performance and longevity.
The DRS250~DRS500 employs 40Cr forgings, subjected to intensive tempering treatment.
This material is renowned for its high tensile strength, undergoing comprehensive quenching and surface treatment, achieving an HB300-380 hardness rating.
The expertly crafted walking wheel incorporates a guiding function, with optional wheel flange guidance to suit specific needs.
guiding function. If wheel flange guidance is used, the minimum
gap between the inner surface of the wheel flange and the edge of
the track can be as small as 1mm. The same gap can also be
obtained by arranging guide wheels. If there is an expected
increase in wear, the walking wheel tread or guide wheel rim can be
hardened to HRC56 ± 2 (HB530) without slipping. The hardening of
the walking wheel is only to reduce wear.
polyurethane
Polyurethane is a synthetic rubber material that has better
resistance characteristics compared to other synthetic rubbers.
Compared with metal materials, polyurethane walking wheels have
a significantly high coefficient of friction, making them suitable for
applications with high dynamic response. It has excellent shock
absorption characteristics, so the walking noise can be minimized.
Please note that compared to metal walking wheels, the
load-bearing capacity of polyurethane walking wheels will be
greatly weakened. Due to the low ground contact pressure, walking
wheels made of polyurethane material are particularly suitable for
walking on concrete surfaces; Due to the high coefficient of friction
between the tread of the walking wheel and the contact material,
polyurethane walking wheels are also suitable for friction driven
applications with acceleration up to 1.5m/s2. In addition,
polyurethane materials are suitable for use at temperatures up to
100 degrees Celsius.
Hardening of wheels
When the running wheels are severely worn during operation (such
as when a large amount of iron filings are found on the track edge),
the tread and rim of the metal running wheels can be hardened (to
a depth of 2-3mm), and the running wheels of DRS112~DRS200
will not have rim damage markings. The hardness value reaches
HRC56 ± 2 (HB530).4

·Wheel blocks with roller guide arrangement
The permissible horizontal force on wheel blocks fitted with a roller guide arrangement should be carefully monitored, not exceeding 15% of the actual wheel load. For DRS112~DRS200 models with travel wheel variant E, this value is more precisely limited to 12%.

Exception: For DRS200 models equipped with a top connection, the permissible horizontal force is distinctly limited to 10% of the actual wheel load. If higher horizontal loads are anticipated, the roller guide arrangement offers flexibility by being fitted to the steel superstructure, rather than directly on the wheel block.
