The safe forklift valve control system comprises a multi-way valve, a descending electromagnetic valve is connected to a descending control oil channel of the multi-way valve in series, an oil inlet electromagnetic valve is connected to an oil return channel of the multi-way valve in series, and the power end of the descending electromagnetic valve and the power end of the oil inlet electromagnetic valve are electrically connected with a pressure switch installed on a seat through a relay. And the on-off of oil ways of the descending electromagnetic valve and the oil inlet electromagnetic valve is controlled through the on-off of the pressure switch. The pressure switch is installed on the seat to control on-off of the descending electromagnetic valve and the oil inlet electromagnetic valve in the multi-way valve, so that operation of the forklift is achieved, operation safety is remarkably improved, and once a driver leaves the seat or the sitting posture is incorrect, operation of the corresponding valve operating rod, the door frame and accessories cannot act.
本申请提供一种安全的叉车阀操控系统,包括多路阀,所述多路阀的下降控制油道上串接有下降电磁阀,多路阀的回油道上串接有进油电磁阀,所述下降电磁阀和进油电磁阀的电源端均通过继电器与安装在座椅上的压力开关进行电连接,通过压力开关的开关来控制下降电磁阀和进油电磁阀油路的通断。本申请通过在座椅上安装压力开关来控制多路阀中下降电磁阀和进油电磁阀的通断,来实现对叉车的操作,显著提高了操作的安全性,因为一旦驾驶员离开座椅或者坐姿不正确,操作相应的阀操纵杆,门架及属具都不能动作。
