Abstract

The present invention provides a large-tonnage forklift truck, that is, the functions of the loader and the large-tonnage forklift are combined into one, and the boom of the original loader is shortened, thereby changing the fulcrum of the lifting cylinder on the boom, so that The active force arm on the swing arm becomes longer and the transmission force arm becomes shorter; and the rotating shaft set on the rocker arm is moved down to make the active force arm on the rocker arm longer and the transmission force arm shorter; lower the lifting cylinder in The connection point on the front frame makes the angle between it and the front frame smaller and has stronger thrust; and the diameter of the lifting cylinder is increased to increase the oil pressure of the lifting cylinder to increase the weight of the fork. The present invention combines the operating functions of large-tonnage forklifts and loaders, through the comprehensive integration of machinery, electrical appliances, and hydraulic pressure, and at the same time has the advantages of flexibility and off-road performance of loaders, and the advantages of large loading capacity of large-tonnage forklifts, and reduces fuel consumption. Relatively small, it can load and unload 25 tons of stone blocks, and can lift the goods to a height of more than 3200mm.

Description

technical field [0001] The invention relates to a forklift truck, which is a large-tonnage forklift truck which combines a large-tonnage forklift truck and a loader into one. Background technique [0002] Existing stone mines are mined by mechanization. In the past, traditional loaders and large-tonnage forklifts were mostly used for the overturning, transfer, loading, stacking, and retrieval of stone blocks on the production line. Due to the low rated load of the loader, generally below 8 tons, it cannot load large-tonnage stone blocks, resulting in low production efficiency and serious safety problems. However, due to its low chassis and weak cross-country performance, the large tonnage forklift has a limited forward distance of the fork, which limits its loading capacity. Contents of the invention [0003] The purpose of the present invention is to provide a large-tonnage forklift, which combines the advantages and functions of the loader and the large-tonnage...
