Problems solved by technology

[0003] In factories and workshops, due to space constraints, workers generally use relatively small cranes to transfer goods and hoist items. The existing small cranes generally have a low chassis. When working in potholes with stagnant water, The water in the pit has certain damage to the chassis of the crane and various equipment installed on the chassis, and has certain potential safety hazards. At the same time, the weight of small cranes is generally light, and the center of gravity will be unstable when lifting some heavy items. , further increasing security risks

Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] refer to Figure 1-Figure 4 , an adjustable self-propelled hydraulic crane, including a chassis 1 and a crane mechanism 2, a rotatable rotating disk 11 is installed on the chassis 1, and the crane mechanism 2 is arranged on the rotating disk 11. The crane mechanism 2 includes a supporting main arm 21 , a telescopic arm 22 , an angle control cylinder 23 , a telescopic cylinder 24 and a crane 25 . The supporting main arm 21 is vertically installed on the top of the rotating disk 11 , and the outer cylinder of the telescopic arm 22 is hinged to the end of the supporting main arm 21 away from the rotating disk 11 . The angle control cylinder 23 is arranged between the supporting main arm 21 and the telescopic arm 22, and its two ends are respectively hinged with the outer tubes of the supporting main arm 21 and the telescopic arm 22. The telescopic cylin...

Abstract

The invention relates to an adjustable self-walking hydraulic crane. The adjustable self-walking hydraulic crane comprises a chassis and a crane mechanism, the crane mechanism is arranged on the chassis through a rotating disc, a lifting moving mechanism capable of lifting the chassis is arranged at the bottom of the chassis, and a safety auxiliary mechanism capable of enabling the adjustable self-walking hydraulic crane to be stably parked is arranged above the chassis. According to the adjustable self-walking hydraulic crane, the height of the chassis can be increased, so that the possibility of equipment damage during wading is reduced, and the potential safety hazard is further reduced; and meanwhile, when articles are hoisted, high safety and stability are achieved.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to an adjustable self-propelled hydraulic crane. Background technique [0002] Crane is a kind of lifting and handling machinery, which is often used in hoisting equipment, transshipment of goods, emergency rescue and other fields. [0003] In factories and workshops, due to space constraints, workers generally use relatively small cranes to transfer goods and hoist items. The existing small cranes generally have a low chassis. When working in potholes with stagnant water, The water in the pit has certain damage to the chassis of the crane and various equipment installed on the chassis, and has certain potential safety hazards. At the same time, the weight of small cranes is generally light, and the center of gravity will be unstable when lifting some heavy items. , further increasing security risks. Contents of the invention [0004] The purpose of the present invent...
