Arm type four-wheeled cross-country forklift

Abstract

The invention discloses an arm type four-wheeled cross-country forklift. The arm type four-wheeled cross-country forklift comprises a forklift body and a forklift system, wherein the forklift system is mounted on the forklift body, and comprises a cargo fork, a sliding power device, a sliding driving device, a swinging power device and a swinging driving device; the sliding power device is used for driving the cargo fork to slide back and forth along a rail through the sliding driving device, so that the cargo fork is lifted up or put down; the swinging power device is used for driving the cargo fork to swing through the swinging driving device so that the inclined angle, relative to the horizontal plane, of the cargo fork is adjusted. The arm type four-wheeled cross-country forklift has the beneficial effects that the swinging range of the cargo fork is large and the tail end of the cargo fork is upwards raised, so that cargoes are prevented from falling from the cargo fork; the trafficability characteristic in the vertical direction is good; two wheels or four wheels are used so that the road surface trafficability characteristic is improved.

Description

Technical field [0001] The invention relates to a forklift, in particular to an arm type four-wheel drive off-road forklift. Background technique [0002] At present, the main forklifts produced in my country are mainly from double or triple mast and front wheel drive rear wheel steering and swing. Regarding multi-layer mast, there are 8 guide bearings, 4 chain bearings and 2 hydraulic The cylinder has 2 chains and 2 masts, which is very complicated. Moreover, the existing front-wheel-drive forklifts are limited to work in warehouses and flat roads. If they encounter steep slopes, gravel, icy and snowy roads, it will be difficult to work. (The background art should be limited to describing the defects of the prior art.) Summary of the invention [0003] The purpose of the present invention is to provide an arm type four-wheel drive cross-country forklift that uses only one cylinder, omits the above-mentioned bearings, cylinders, chains, masts and other devices, and controls the f...

[0002] At present, the main forklifts produced in our country are mainly from the double or three-layer mast and the front wheel drives the rear wheel to steer and swing. Regarding the multi-layer mast, there are 8 mast bearings, 4 guide bearings, 4 chain bearings, 2 hydraulic pressure 2 oil cylinders, 2 chains and a mast, very complicated

Moreover, the existing front-wheel drive forklifts are only limited to work in warehouses and flat roads. If they encounter steep slopes, gravel, ice and snow roads, it will be difficult for this truck to work.
