Note

*1: The saddle is coated for rust prevention only.
*2: THC5-56, THLC5-56 and THMC5-45 are for the double rail type.
*3: (4.0)* shows the maximum wheel weight when using a mono-rail.
*4: Sudden breaking will be applied and the load might swing bigger when the speed of trackless wheel is changed from standard to creep because the polyurethane wheels are slipless. In this case, a mechanism like a time lag circuit is necessary.
*5: Rating shows the total value of standard speed and creep speed.
