The national standard high manganese alloy steel is adopted, which has stronger bearing capacity. The body is added with multiple stiffeners to ensure that the carriage will not be damaged when loading; 180 degree slewing frame, turning radius (180 degree in-situ turning), flexible steering and convenient operation; The solid tires of well-known brands of domestic engineering vehicles are used, with high elasticity and wear resistance; Rotary mechanism with stable performance; Non standard configurations such as brake (air brake or oil brake), shock absorption and roof can be provided according to customer requirements; Double suspension racks can be configured in particularly harsh working conditions; Buffer type traction mechanism: under the impact force, the parts of the full trailer will generate great power, which may cause damage, and the surrounding machinery and buildings may also be damaged. Therefore, all engineering machinery should take buffering or isolation measures against all unnecessary impact forces. The buffer type traction mechanism used in this vehicle can minimize the impact force on mechanical equipment. This flat trailer is mainly used for the transportation of industrial raw materials or finished products such as paper mills, household appliances, chemicals, etc. The traction frame of this vehicle is equipped with shrapnel, which can be reset automatically.
