Modular Travelling Systems for
Crane End Carriages,
Sliding Roofs (Openable Roofs)
Main single wheel units are equipped with various accessories according to their special functions & jobs. But they are always joined or united with a main body, a system or with each other by electrical welding. The body of main unit is rectangular tubular steel profile.
The wheels may be special steel as 4140 alloy steel, GGG-70 copper alloyed spheroidal cast iron or may be kestamid or polyamide etc. due to their wheel sizes, required loading capacities and velocities etc. Wheel base diameters and shapes may differ at standard sizes according to their functions. They may be entirely flat, conical or circular grooved or one or two sides tapered etc.
Units can be either locomotive or vagonet type. Locomotive units can be activated (driven) by electrical motors with gear box units and brakes. The wheel of the unit can be directly driven by an hub shaft or by a pinion gear when wheel is of geared type.
Locomotive type wheel units or driving units consist of rectangular tubular steel profile, wheel, motor driving unit that composed of electrical motor with gear box and brake, bumper plate with rubber bumper, ridge plate and saddle plate.
Vagonet type wheel units or driven units consist of rectangular tubular steel profile, wheel, bumper plate with rubber bumper, ridge plate and saddle plate.
