The invention discloses a large-tonnage lifting platform and a control method thereof. The large-tonnage lifting platform comprises a carrying part and a slope platform connected with the outer side of the carrying part. The lifting part is used for controlling the carrying part to lift and comprises a check valve, a balance valve and a hydraulic cylinder, and the hydraulic cylinder is respectively connected with the carrying part and the check valve; the balance valve is respectively connected with the check valve and the oil supply part. The forklift is lifted to the preset height through the lifting platform to load and unload goods, the problem that the goods which are too high are difficult to load and unload is solved, the check valves are additionally arranged at the front ends of the hydraulic cylinders respectively, the oil mass pressure of each oil cylinder can be locked to be not changed, and the bearing stability and the translation stability of the platform are better.
本发明公开了一种大吨位升降平台及其控制方法,载物部,与载物部外侧连接的斜面平台;控制载物部升降的升降部,升降部包括止回阀、平衡阀和液压缸,液压缸分别连接载物部和止回阀;供油部,平衡阀分别连接止回阀和供油部。通过升降平台将叉车抬升至预设高度装卸货物,解决高度过高的货物难以装卸的问题,且液压缸的前端分别加装止回阀,能够锁死每条油缸的油量压力不会变化,使平台的承重、平移稳定性更好。
