pendulum), lowering link, TSU-1Zh (crossbar) and TSU-1Zh-01 (double crossbar) which pro-
vide coupling and transportation of trailed and semi-trailed machines (with the TСУ-2 – semi-
trailers), coupling devices of which correspond to the following requirements:
- compatibility of coupling dimensions;
- the machines have rigid trailed devices;
- draft poles of the trailers are equipped with the device, which facilitates coupling-
uncoupling with tow hitches of the tractor;
- trailer hitches have adjustable bearing part.
