STK-59GMS Mobile Workshop
STK-59GMS mobile welding/processing workshop is essentially a tracked chassis accommodating processing compartment and hydraulic manipulator.
The workshop is based on the ATS-59G tracked tow tractor that features high maneuverability and cross-country capability.
The tow tractor is fitted with a hitch-mechanism enabling it to tow a trailor. The connection head of the pneumatic system of the chassis allows using the pneumatic drive of the trailor brake control. The tow tractor is fitted with a starting preheater, enabling low-temperature engine starting. The primary engine starting is by an electric starter with the secondary starting by air. The vehicle is fitted with a winch installed in the rear part of the chassis. The enclosed cab of the tractor ensures comfortable work for a crew of six.
The processing compartment comprises enclosed heat-insulated box-body accommodating two diesel-powered Ranger 305D CE welding plants and an oven for drying welding electrodes with a 40kg capacity. Two containers accommodating 6 compressed air bottles (carbon dioxide and argon) are located outside the processing compartment. The hydraulic manipulator controlled from inside the cab is installed in the front part of the chassis. The manipulator capacity with the maxed boom-out is 770 kg.
