The invention discloses a lifting appliance control hydraulic circuit, a reach stacker hydraulic control system and a reach stacker, and belongs to the technical field of reach stackers. The lifting appliance control hydraulic loop comprises a leveling oil cylinder, a leveling valve group and an oil supply port P1; the leveling valve group comprises a first leveling valve, a second leveling valve and a reversing control valve; when the first leveling valve and the second leveling valve are switched on at the same time, the lifting appliance performs self-adaptive leveling under the action of gravity; the reversing control valve is provided with a first conduction mode and a second conduction mode; the first conduction mode and the second conduction mode are switched through the reversing control valve, and the inclination direction of the lifting appliance is switched. The lifting appliance can be leveled in a self-adaptive manner, the inclination direction of the lifting appliance is switched, and the lifting difficulty is reduced.
本发明公开了一种吊具控制液压回路、正面吊液压控制系统和正面吊,属于正面吊技术领域。吊具控制液压回路包括调平油缸、调平阀组和供油口P1;调平阀组包括第一调平阀、第二调平阀和换向控制阀;当第一调平阀和第二调平阀同时导通时,吊具在重力作用下进行自适应调平;换向控制阀设有第一导通模式和第二导通模式;通过换向控制阀切换第一导通模式和第二导通模式,对吊具倾斜方向进行切换。本发明能够使吊具进行自适应调平、对吊具倾斜方向进行切换,降低吊装难度。
