Use of limit switches on hydraulic high-altitude lifts

August 28, 2023

Limit switches are widely used in various machine tools and lifting machinery, such as hydraulic lifting platforms, aluminum alloy lifts, aerial work platforms, aerial work platforms, lifts, aerial work equipment, aerial work lifts, mast-type aerial work platforms, scissor-type high-altitude Work platform, crank-type aerial work platform, straight-arm aerial work platform, hydraulic freight elevator, used to control its travel, terminal limit protection. In the control circuit of the elevator, the travel switch is also used to control the speed of the switch car door, the limit of the automatic door opening and closing, and the upper and lower limit protection of the car.

The limit switch is a kind of position switch. It is a commonly used small current main electric appliance. It uses the collision of the moving parts of the production machinery to make the contact action to realize the connection or breaking control circuit to achieve certain control purposes. Typically, such switches are used to limit the position or travel of the mechanical motion, causing the motion machine to automatically stop, reverse, shift, or automatically reciprocate at a certain position or stroke.

In the electrical control system, the role of the limit switch is to achieve sequential control, positioning control and position status detection. It is used to control the stroke and limit protection of the machine. The structure consists of the operating head, the contact system and the outer casing.

In the actual production of the hydraulic lift, the limit position is installed in a pre-arranged position. When mounted on the aerial work platform, the aerial work vehicle, and the module on the mechanical moving parts of the aerial work equipment hits the travel switch, the limit travel switch The contact action realizes the switching of the circuit. Therefore, the limit travel switch is an electric appliance that switches the circuit according to the stroke position of the moving part, and its action principle is similar to that of the button.
