Description

technical field [0001] The invention relates to a fork lifting device and a battery forklift, in particular to a battery-powered forklift which adopts an electric ball screw driving device instead of a fork driving oil cylinder. Background technique [0002] At present, the lifting pressure of the battery-powered forklifts used in warehouses, supermarkets and other occasions is provided by the fork drive cylinder. When the forklift is working, the motor drives the hydraulic pump to rotate, and then the hydraulic pipeline is connected to each oil cylinder, and the oil circuit is controlled by manual and electric valves. But the existing hydraulic system has the following problems: [0003] 1. The connection of the hydraulic pipeline is complex and prone to oil leakage and the installation of the system is inconvenient. [0004] 2. The efficiency of hydraulic transmission is low, so battery forklifts generally use a separate motor to drive the hydraulic pump. Due to the wor...
