Abstract

The utility model relates to the field of object transportation vehicles, in particular to a rotatable suspension arm for a trailer, which comprises a suspension hook, a base arranged on the trailer, a suspension arm, a lifting oil cylinder and a supporting arm. The rotatable suspension arm for the trailer is characterized by further comprising a rotation bearing arranged between the base and the suspension arm, a rotation distributor arranged in the rotation bearing, a middle section suspension arm arranged in the suspension arm, a tail section suspension arm arranged in the middle section suspension arm and a telescopic oil cylinder penetrating through two ends of the suspension arm, the middle section suspension arm and the tail section suspension arm and respectively connected with the hanging arm and the tail section hanging arm. A suspension hook is arranged on the end portion of the tail section suspension arm. The rotatable suspension arm for the trailer is small in size, capable of rotating flexibly and capable of suspending or discharging small objects automatically, thereby improving efficiency for object transportation loading.

Description

Trailer is used rotatable arm

Technical field

The utility model relates to the defeated vehicular field of goods, is specially a kind of trailer and uses rotatable arm.

Background technology

Needing driving on one side or crane to cooperate during tradition trailer handling goods could lifting cargo, and when the less goods of trailer load volume, use driving perhaps crane then degree of utilization is low, with high costs; And use manpower then can not move the excessive goods of weight, there is inconvenience.

Summary of the invention

The purpose of the utility model is: provide a kind of and be loaded on the trailer, volume is little, and is rotatable, can lift by crane the rotatable arm of small-sized Loaded goods.

In order to achieve the above object, the utility model is achieved in that

A kind of trailer is used rotatable arm; It comprises suspension hook, be arranged at the trailer middle part pedestal, be used to control the elevating ram that arm goes up and down, the hold-down arm that is used to support arm with pedestal and arm bonded assembly respectively with pedestal bonded assembly arm and two ends, also comprise the pivoting support that is arranged between pedestal and the arm; Be arranged at the revolution distributing box in the pivoting support; Be located in the arm and with the stage casing arm of its sliding block joint; Be located in the arm of stage casing and with the latter end arm of its sliding block joint; And the two ends in arm, stage casing arm, the latter end arm are used to drive the telescopic oil cylinder of stage casing arm, latter end hoisting arm expansion respectively with arm and latter end arm bonded assembly; Suspension hook is located at the end of terminal arm.
