Problems solved by technology

It is suspected that the goods are overweight, so we can only give up self-loading and unloading, which affects work efficiency
Once there is an error in the confirmation of overweight cargo, an accident may occur

Embodiment Construction

[0018] refer to figure 1 , the traction vehicle lifting transport vehicle of the present invention includes a tractor 1, a trailer 2, and a crane (hoist) machine 3 installed on the tractor.

[0019] Refer to 2, image 3 , Figure 4 , two groups of beams 4 fixed on the front and rear of the chassis of the tractor, each group of two beam boxes can respectively protrude to the left and right lifting load beams 5, between the load beam 5 and the beam box 4 An oil cylinder 6 for controlling the extension and retraction of the load beam, and a lifting leg 7 hinged at the outer end of the load beam 5 . A longitudinal telescopic beam 8 is arranged at the rear end of the chassis of the tractor to cooperate with the chassis or a socket member fixed on the chassis. The beam box 4 at the rear of the tractor is fixed on the outer end of the telescopic beam 8. Install telescopic beam control oil cylinder 9.

[0020] refer to Figure 4 , Figure 5 , Figure 6 1. A tenon 10 protruding ...

Abstract

A traction truck with a loading crane comprises a tractor, a trailer, the crane installed on the tractor, lifting load-bearing beams, oil cylinders, lifting supporting legs and two telescopic supporting legs. The lifting load-bearing beams extend out of the front portion of a chassis of the tractor, a beam box at the rear end and the interior of the beam box leftwards and rightwards. The oil cylinders drive the lifting load-bearing beams to stretch out and retract back. The lifting supporting legs are arranged at the outer ends of the lifting load-bearing beams. The two telescopic supporting legs are arranged at the front end of the trailer. The traction truck is characterized in that a longitudinal telescopic beam is arranged at the rear end of the chassis of the tractor; the beam box is fixed to the outer end of the telescopic beam; the outer end of each load-bearing beam is provided with an insertion tenon installed in a casing pipe; each casing pipe is fixed to the end of the corresponding load-bearing beam; and a telescopic oil cylinder is arranged between each casing pipe and the corresponding insertion tenon. The two sides of the trailer are provided with casing pipe type mortises corresponding to the insertion tenons and insertion tenon clamping boards are installed in the mortises. Telescopic supporting legs are arranged at the rear end of the trailer. The traction truck with the loading crane has the beneficial effects that the tractor and the trailer are laterally and firmly connected, the lifting and supporting span is enlarged, and the balance weight is increased. Potential accident hazards in self-loading-unloading operation are eliminated and the operation efficiency is improved.

Description

technical field [0001] The invention belongs to the field of vehicles, in particular to a self-loading and unloading freight vehicle. Background technique [0002] In the past, tractors (semi-trailer trucks) that transport large cargo such as containers can only be loaded and unloaded at places with relatively large cranes. In order not to be restricted by lifting equipment at the loading and unloading site, some vehicles of this type are equipped with a truck-mounted crane (crane) on the tractor and a rigid support mechanism for the car body during lifting operations, so that the tractor has the function of a crane. Structure and function. Previously, semi-trailer trucks equipped with lifting tractors used self-provided cranes to load and unload goods relative to the trailers. After supporting the towed end of the trailers relative to the ground, the tractors and trailers were separated. According to the storage position of the trailer relative to the goods on the ground, ...
