Embodiment Construction

[0035] Below, take the case of using on a lift truck as an example, refer to Figure 1 to Figure 1 2. Embodiments of the self-propelled work machine of the present invention will be described.

[0036] first, Figure 1 to Figure 7 The first embodiment of the present invention is shown. Here, 1 is an elevating loading and unloading vehicle. This elevating and unloading loading and unloading vehicle 1 is roughly composed of a wheeled vehicle body 2 capable of self-propelling and a boom device 11 described later. A machine for loading and unloading goods from the ground to a high place.

[0037] Here, the vehicle body 2 is roughly composed of a frame 3 formed of a thick steel plate or the like extending in the front-rear direction; a drive source (none of which is shown) such as an engine, a hydraulic pump, and a hydraulic motor mounted on the frame 3; In addition, left and right front wheels 4 (only the left side are shown) are provided on the front part side of the frame 3, ...

Abstract

A tool repositioning mechanism ( 20 ) is provided between a fore end of a telescopic boom ( 12 ) and a cargo handling tool ( 35 ). The tool repositioning mechanism ( 20 ) is constituted by a head member ( 21 ), swing arm ( 25 ), swing cylinder ( 29 ), tool mount member ( 30 ) and a link ( 34 ). As a swing cylinder ( 29 ) is expanded or contracted, the cargo handling tool ( 35 ) is shifted to the right or to the left of the telescopic boom ( 12 ) through the tool repositioning mechanism ( 20 ). Accordingly, even if a spot of a lifted cargo on the cargo handling tool ( 35 ) is deviated from a cargo unloading spot in a lateral direction, the position of the lifted cargo can be adjusted easily by the tool repositioning mechanism ( 20 ) to unload the cargo accurately on a specified spot.

Description

technical field [0001] The present invention relates to a self-propelled working machine having a self-propelled body, such as a lift truck. Background technique [0002] In general, as a working machine used in high-altitude operations such as cargo transfer work (loading and unloading work) from the ground to high places or maintenance work on electric wires, there is known a vehicle body that can move on its own, and is installed on the ground so that it can rise and fall. A self-propelled work machine with a cantilever on the vehicle body (for example, refer to Japanese Patent No. 2559831). [0003] And, according to the cantilever device of this lifting type loading and unloading vehicle of this prior art, the base end side can be installed on the car body undulatingly, the front end side is forward and backward, and the multi-stage telescopic cantilever is telescopic, and is arranged on the telescopic cantilever. The fork on the most forward cantilever in the arm cons...
