Abstract

The invention provides an omnidirectional running-type forklift truck, belonging to material handling machinery. The prior forklift truck needs to do rotary motion around some instantaneous rotation center when the forklift truck turns, thereby requiring large auxiliary space. The omnidirectional running-type forklift truck comprises a driving wheel, a back supporting wheel, a front steering wheel, a driving wheel steering device and a front wheel steering device. The driving wheel steering device comprises a redirector for a steering wheel, a steering motor and a transmission mechanism connected between the steering motor and the driving wheel. The front wheel steering device has a steering cylinder arranged on a forward-extending leg; the steering cylinder drives a front steering wheel revolving body through a connecting rod; the steering cylinder is connected to a steering valve through a steering oil pipe; and an operating handle is connected with the steering valve. When the forklift truck handles super-wide goods in crisscross goods shelf channels and needs to enter a vertical channel, the forklift truck does not need to turn but only move transversely, and then the length direction of the super-wide goods is in accordance with the running direction of the forklift truck; therefore, the huge auxiliary steering space of the prior forklift truck does not need to be provided, so as to greatly save precious storehouse space.

Description

technical field [0001] The invention relates to a material handling machine, in particular to an omnidirectional traveling forklift. Background technique [0002] Traditional four-point (four-wheel) forklifts are usually front (double) wheel drive and rear (double) wheel steering; traditional three-point (three-wheel) forklifts are usually front (double) wheel drive and rear (driven) wheel steering Or front (double) wheel driven, rear wheel drive and steering. Their common feature is that when the forklift is loaded with ultra-wide goods (such as long logs, steel pipes, etc. that are larger than the width of the forklift body or even larger than 5-10 meters long) turn When turning, it is inevitable to make a turning motion around a certain instantaneous turning center. In other words, when a traditional forklift is turning a long cargo in a vertically and horizontally intersecting shelf channel, it is required to provide a large auxiliary space (the technical term is the min...
