Lifting platform is a vertical transport of people or things lifting machinery. It also refers to the vertical conveying equipment in the logistics system such as factories and automatic warehouses. The lifting platform is often equipped with a variety of plane conveying equipment, as the connecting device of different height conveying lines. Generally using hydraulic drive, it is called hydraulic lifting platform. In addition to the different heights of cargo transport, widely used in high altitude installation, maintenance and other operations. The characteristics of lifting platform free lifting has been widely used in municipal maintenance, cargo transportation, logistics center, building decoration, etc., the installation of car chassis, battery car chassis can walk freely, the working height space has also been changed.
working principle:
The lifting button is used to control the closing of the contactor, connect the power supply of the electric motor, and the electric motor runs to drive the hydraulic pump to work. Under the pressure of the hydraulic pump, the hydraulic oil enters the lower end of the hydraulic cylinder through the oil filter, the explosion-proof electromagnetic directional valve, the throttle valve, the hydraulic control check valve, the balance valve, and the explosion-proof valve. The hydraulic oil acts on the piston, pushing the piston rod upward, and driving the lifting platform to rise, The return oil from the upper end of the hydraulic cylinder returns to the oil tank through the flameproof electromagnetic directional valve. Its rated pressure is adjusted through the overflow valve, and the reading value of the pressure gauge is observed through the pressure gauge. When reaching the set position of the lifting platform, disconnect the power supply of the contactor control circuit through the travel switch, disconnect the contactor, cut off the power supply of the electric motor, and the lifting platform stops at the specified position. Connect the electromagnetic reversing valve of the pressure relief circuit through the lowering button and relay. Under the action of the gravity of the lifting platform itself and the gravity of the cargo, the piston rod of the hydraulic cylinder moves downward. The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic reversing valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic one-way valve, throttle valve, and explosion-proof electromagnetic reversing valve When reaching the designated position, cut off the power supply of the solenoid directional valve of the pressure relief circuit through the travel switch, and the lifting platform stops at the designated position.
The lifting table adopts air spring for lifting, and its braking is safe and reliable. It can effectively control the lifting speed and prevent accidents. It can also ensure that the hydraulic pipeline can be locked safely in case of accidental burst. Guangzhou Tieying Gas Spring Technology Co., Ltd. has been specialized in making gas springs for 20 years, and has obtained ITAF 16949 and 200000 times durability test certificate. The products are durable and practical, with no gas or oil leakage. Welcome you to come for consultation.
