Abstract: A new type of bedstand for forklift gantry is introduced in the paper. The bedstand adopts hydraulic driving technology,with laser range finder to measure the lifting height of gantry fork and angle sensor to measure the inclination angle of the gantry. The pressure and flow of each system are measured by pressure sensors and flow sensors,and the data is transmitted to the control system. The control system drives the corresponding valve group action through the predefined parameters,so as to realize the automatic cycle test of forklift gantry. The control system can realize a variety of cycle actions of different parameters and realize unattended automatic cycle test. The pressure,flow,temperature and other physical quantities of each loop of the system are collected in real time during the test,and the curves of different parameters can be drawn,so as to evaluate the performance of the forklift gantry. The distance between the front and back of the mounting support and the left and right of the mounting support of the bedstand are stepless adjustable,which can adapt to the mounting structure and size of the forklift gantry of different tonnage and models,and can realize performance test and reliability fatigue test of forklift gantry assembly system of different tonnage.
