DFA One Towing Two Platform Type Tow Truck

I. Platform mechanism description 

The platform is sliding rail type and it is driven by oil cyinders. It is made of Q345 high strength steel plate with reasonable structure.The surface of the platform adopted not only reduces dead weight but also facilitates the use of tools like bangdage

The minimum inclination angle is of 8 degree when the platform is fully extended, and the slope is relatively gentle to make sure there is no contact with vehicle bottom during the whole loading & unloading process.

II.  Lifting system

Lifting system is driven by internal & external sleeve sliding type oil cylinder made of Q345. And it has advantages like large lifting force and stability under the condition of strength. The working model is as follows: When the cylinder low down the lifting arm, the telescopic arm extends until the front bracket of the swinging arm reaches the lifting position of vehicle. An then place the rear bracket and insert the plug, tie up the lifting arm with towed vehicle with bandage. And with the contraction of oil cylinder, the vehicle is lifted.

III. Operation mechanism
