Three-way stacking forklift with portal capable of moving laterally and moving along with rotation

Abstract

The invention provides a three-way stacking forklift with a portal capable of moving laterally and moving along with rotation. The forklift comprises a pallet fork, a pallet fork frame, a portal framesystem, a bridge frame assembly, a lateral moving sliding frame, a forklift body system and a rotating shaft, the pallet fork frame is movably installed on the portal frame system, the lateral movingsliding frame is fixedly installed at the front end of the forklift body system, the bridge frame assembly is movably installed on the lateral moving sliding frame, and the portal frame system is rotationally installed on the bridge frame assembly. The bridge frame assembly is not lifted along with the pallet fork by laterally moving the sliding frame, therefore, the actual lifting weight of thethree-way stacking forklift with the same lifting tonnage is reduced by nearly more than half compared with that of the traditional manual descending three-way stacking forklift, so the loss of the energy consumption of the assembly can be effectively reduced; the gantry system is fixed on the forklift body system and can rotate and laterally move along with the fork instead of being fixed on theforklift body system, so that the gantry system rarely shields the sight of a driver in the process of forking and stacking cargoes, and the forklift is excellent in driving view and high in safety.

Description

technical field [0001] The invention relates to the technical field of forklift components, in particular to a three-way stacking forklift with a mast moving sideways and following rotation. Background technique [0002] The traditional man-down three-way stacking forklift mast system is installed on the vehicle body, and does not rotate or move sideways with the fork. The side-moving carriage and bridge components are lifted and lowered simultaneously with the fork. The weight of the side-moving carriage and bridge components is relatively large. During the lateral movement of the three-way forklift after picking up the goods, the mast is subject to a large lateral load. Therefore, the structure of the traditional three-way stacking forklift mast system is complex. The oil pipes, chains, oil cylinders, etc. arranged on the car block the driver's line of sight a lot, seriously affecting the driver's field of vision. Just as the battery three-way stacking forklift with teles...

Problems solved by technology

The weight of the side-moving carriage and bridge components is relatively large. During the lateral movement of the three-way forklift after picking up the goods, the mast is subjected to a large lateral load. Therefore, the structure of the traditional three-way stacking forklift mast system is complicated. The oil pipes, chains, oil cylinders, etc. arranged on the car block the driver's sight a lot, seriously affecting the driver's vision

Just as the battery three-way stacking forklift with telescopic fork provided by the publication number CN206872354U, it drives the fork to rotate through the rotating mechanism to realize the movement in three directions of the fork, and the fork needs to move up and down along the forklift mast Therefore, the rotating mechanism also needs to move synchronously with the fork, so the fork, as a part of the fork, needs a greater lifting force to move when working, and the fork is integrated with the drive mechanism, so it will not move when forking Obstruct the driver's line of sight
