Cylinder: the cylinder is the main part of the Acrow Prop, used to hold the hydraulic oil and generate thrust.
Live column: the live column is the upper load-bearing rod of the pillar, usually composed of the column head, spring hook, live column cylinder, etc., responsible for telescopic movement under the action of hydraulic pressure.
Handle body: the handle body is connected to the cylinder through the connecting steel wire, and it can rotate freely around the cylinder, which is convenient for operation and transportation. The groove of the handle body is usually equipped with a dust ring to prevent dirt from entering the cylinder.
Three-use valve: three-use valve is the key control element of the Adjustable Props, with the functions of safety valve, unloading valve and check valve, used to control the lifting and lowering of the strut and maintain constant resistance.
Limit device: the limit device is used to limit the expansion and contraction range of the live column, preventing the column from being damaged when it is over-expanded.
Base: The base is the bottom support part of the Adjustable Props, which is usually composed of the base body, spring hanging ring, O-shaped sealing ring, anti-squeeze ring, etc. It is connected by connecting steel wire and oil cylinder to realize the sealing and bearing of the bottom of the strut.
Reset spring: the role of the reset spring is to make the living column body quickly reset when returning to the column, shorten the time to return to the column.
Top cover: the top cover is usually located on the top of the column, used to close the cylinder and protect the internal parts.
In addition, the monolithic Acrow Prop may also include column cap, sealing plug, connecting sleeve, extension sleeve and other components, which work together to make the Acrow Prop work stably under various working conditions.
