Description

High-safety multi-steering lateral-movement AGV fork truck

Technical Field

The invention relates to the technical field of carriers, in particular to a high-safety multi-steering lateral-movement AGV fork carrier.

Background

The conventional AGV fork truck adopts a single steering wheel structure, can only carry out three working modes of forward movement, backward movement and large tail flicking turning, has low flexibility, is difficult to use under the condition of limited field area, needs to reserve enough space for turning in the field due to large rotating radius, and has low space utilization rate; the double-steering-wheel AGV omnidirectional vehicle can realize steering and side shifting in a narrow limited range, can increase the space utilization rate of a field, and can meet the requirements of the market on the AGV omnidirectional vehicle more, and the omnidirectional AGV vehicle is not limited and is more convenient to plan.

Conventional two helm omni-directional cars are because what adopt is that the diagonal nature installs two helm for whole car height has improved, more need lower fork height to fork truck, consequently traditional diagonal angle two helm structure is not applicable to fork truck, in addition, fork truck promotes structure portal for adopting exposed at present, in factory building space, if there is debris to drop on portal hoisting system carelessly, block hoisting system very easily and cause the damage, if staff's careless touching, can cause serious bodily injury even.
