Embodiment Construction

[0018] The specific embodiments of the present invention will be described below with reference to the drawings.

[0019] Reference figure 1 , figure 2 , The boom of a large-tonnage forklift / loader includes a boom body 1, which is composed of two boom units 11, which are connected as a whole through a front cross beam 12 and a rear cross beam 13 , The front cross beam 12 and the rear cross beam 13 are arranged at the two ends of the boom unit 11, and the positions of the front cross beam 12 and the rear cross beam 13 can be flexibly adjusted as needed to reduce the impact on the line of sight. The boom unit 11 is formed by integrally connecting two boom plates 14 through a connecting beam. The boom plates 14 of the same boom unit 11 are connected by a front beam 15, a middle beam 16 and a rear beam 17 into one body. All boom plates 14 are provided with frame connection holes 141, rocker arm connection holes 142, cylinder connection holes 143, and attachment connection holes 144...

Abstract

The invention relates to a movable arm for a large-tonnage forklift / loader. The movable arm comprises a movable arm main body; and the movable arm main body is formed by two movable arm units, the two movable arm units are integrally connected through a front beam and a rear beam, and the front beam and the rear beam are distributed at the two ends of the movable arm units. Each movable arm unit is formed by at least two movable arm plates which are integrally connected through a connecting beam; vehicle frame connecting holes, rocker connecting holes, oil cylinder connecting holes and accessory connecting holes are formed in the movable arm plates; and the vehicle frame connecting holes, the rocker connecting holes, the oil cylinder connecting holes and the accessory connecting holes of the movable arm plates are respectively distributed coaxially. The movable arm is suitable for the large-tonnage forklift / loader. According to the movable arm, movable arm main plates with heavy weights and large thicknesses can be replaced through a method that a plurality of movable arm plates are combined to form the movable arm units. Thus, the loading requirement can be met, the weight of the movable arm is effectively reduced, and the producing difficulty of the movable arm is reduced.

Description

Technical field [0001] The invention relates to an important component of a forklift / loader, in particular to a composite boom for a large-tonnage forklift / loader. Background technique [0002] As a part of the forklift / loader's working device, the force of the boom is complex and requires good structural strength to ensure service life and safety performance. The mechanical properties of the plate will decrease after the thickness reaches a certain level. Therefore, on a large-tonnage forklift / loader, simply increasing the plate thickness of the boom main board not only makes the boom weight very large, but also difficult to meet the load demand. In addition, due to the assembly requirements of the rocker arm of the traditional boom, a support beam is assembled in the middle of the boom. The two main boom main plates of the existing boom are also connected as a whole through the support beam. This structure makes the boom There is a large instability of the structure, which req...
