Combination road machines on Kamaz basic chassises
Multifunctional mobile floating levelling shovel/excavator TTM 6901E on the chassis of snow/mud truck TTM 6901 is designated for earth-moving works on main pipelines. Is to be exploited in severe climatic conditions, including virgin snows and swamps of all categories and also on the roads with hard coating without it’s breaking. Design of the excavator with fully rotating dipper on telescopic boom allows it’s using as digging-under machine for soil excavation from under the pipe. Truck’s caterpillars are furnished with plastic wear-resistant spreaders. Optionally the truck may be furnished with caterpillars with rubbermetal hinges. Caterpillar snow/mud truck TTM 6901 can fulfil it’s tasks in severe climatic conditions from - 45° C to + 50° C and to negotiate deep loose snow, swamps of all categories, sands and pools. Enhanced negotiability and manoeuvrability of the truck are secured with the using of turning-coupling device, locking of inter-body and inter-axle differentials, low pressure on the ground, high power density and big ground clearance. The height of the raps of the freight platform is 0,6 m. The body of the truck is metal welded with three seats cabin. Inside the body YaMZ-238B engine of 300 hp is installed. Four-stages mechanical gear box provides speed range from 3 to 18 km/h. The capacity of fuel tanks – 500l. Average pressure on the ground – 0,2 kg/sm2
