Tow truck for special vehicles MAN 45,500 Wrecker Truck

A number of evacuation operations require the use of special technological machines for rescue operations, and towing damaged and lost various types of equipment. Which differs from conventional road evacuation operations both in type and location. This is primarily industry, the mining industry, and large-scale construction sites that require the evacuation of heavy-duty vehicles and special equipment. These are mines, quarries, tunnels. Also, the evacuation of vehicles off-road requires the use of special machines.



For this purpose, a special tow truck MAN 45,500 Wrecker Truck was developed based on the heavy army chassis of the MAN M series, with an 8x8 wheel formula. Atlas evacuation facility. Thanks to the chassis and built-in equipment, this tow truck can be used for evacuation and towing both by partial loading and by direct towing by means of a rod of such equipment as: quarry and off-road dump trucks and dumpers on special tracks with an active movable joint or articulated dump trucks; underground mine dump trucks, off-road heavy tractors; front loaders; wheeled and tracked bulldozers. A special area of the tow truck is the forestry and agricultural sector, which, due to road conditions and an abundance of special equipment, requires the use of unique special tow trucks. In this case, the MAN 45,500 8x8 Wrecker Truck transporter of damaged equipment evacuates row tractors, energy-saturated wheeled and tracked vehicles, combines, harvesters, forwarders and logging trucks.



The chassis of the M-series Military tow truck is a tractor based on a special chassis, which makes this machine similar to high-power tractors. This is the use of a girder frame as a ridge, the use of a bridge chassis scheme with on-board gearboxes and active hydraulic wheel suspension. The engine of the heavy tow truck is a special industrial turbodiesel MTU 6V833 with a displacement of 22 liters and a power of 500 hp. The transmission is built using a hydrodynamic transmission ZF Transmatic WSK.

Atlas built-in evacuation equipment includes three traction hydraulic winches with a developed force of 2 x 25 tons, and one winch for 12 tons. The lifting mechanism in the form of a folding crank manipulator with a cable suspension hook manufactured by Atlas 4300 M5 has a payload capacity of 7 tons at a reach of 3.5 meters, with a maximum boom reach of 9 meters and a lifting capacity of 2.1 tons. To stabilize the crane during lifting operations, there are 4 extendable outriggers in the chassis structure.

The wheels or trolleys of the evacuated equipment are hung out using the partial loading method using the Under Lift device. The device has the form of a rocker arm with a hydraulic device for changing the loading height. The design is designed specifically for hanging equipment during off-road evacuation, and uses STANAG 4478E Recovery Eyes coupling technology for finger couplings or tow hooks. The gripping device has a T-shaped beam to which both replaceable coupling elements and chains are attached for hanging equipment by hooking onto bridges.
