Cantilever tunnel boring machine cylinder

The integrated excavation and support machine combines excavation, temporary support, and anchor rod/cable support functions into one unit. It features a compact structure and a high degree of mechanization. The excavator's oil cylinder is a key component for the main machine's actions, offering high response speed and precise positioning capabilities. It can withstand harsh conditions of high dust and high impact, with reliable sealing to ensure precise coordination of excavation, anchoring, and support actions, providing stable power for efficient and safe construction.

Product Features

• Cutter head lifting cylinder: Used to control the vertical lifting and lowering of the cutter head, allowing the cutter head to adapt to rock cutting operations at different heights and expanding the cutting range.
• Cutter head telescopic cylinder: Allows the cutter head to extend and retract horizontally, adjusting the cutter head's position in different work scenarios to improve cutting flexibility and accuracy.
• Cutter head slewing cylinder: Responsible for driving the cutter head to rotate left and right, achieving cutting of rocks on both sides of the roadway and increasing the cutting coverage area.
• Conveyor plate lifting cylinder: Its main function is to control the lifting and lowering of the conveyor plate. During excavation, by adjusting the height of the conveyor plate, it can better adapt to different ground conditions and effectively collect and load the cut rock fragments.
• Rear support cylinder: When the excavator is working, the rear support cylinder extends to support the rear of the excavator, making the excavator more stable during cutting operations, reducing vibration and displacement, and improving work efficiency and safety.
• Customizable design according to customer needs, including working pressure, size specifications, and installation methods.
