Transport trolley with cable drum

A transport trolley with a cable drum, type 12-156, is intended for the transport of ropes, cables and electric wires in mining excavations. The type 12-156 transport vehicle was made in two construction variants: 1. Version 12-156 - trolley with a drum frame with bearings, enabling 360 degrees rotation around the axis. Placing the drum frame on a ball bearing allows it to be rotated in the direction needed to stretch the cable or rope and to unwind it freely. 2. Version 12-156.1 - a trolley with a fixed drum frame, without the possibility of rotation. A transport trolley with a cable drum is adapted for transport on mine tracks with a rail spacing of 550 ÷ 900 mm. The construction of the cable drum allows it to be removed from the transport car and suspended under the transport set of the suspended railway.
