Telescopic Cylinders for Tunnel Boring Machines
Introduction
Telescopic cylinders are an essential component of tunnel boring machines. These hydraulic cylinders are used to propel the cutting head of the machine forward and provide the necessary thrust to break through the rock or soil.
How do Telescopic Cylinders work?
Telescopic cylinders consist of a series of nested tubes that move in and out of each other. The force required to move the cylinders comes from the hydraulic fluid that is pressurized and transmitted through the cylinder's ports.
Advantages of Telescopic Cylinders
Telescopic cylinders have several advantages over other types of hydraulic cylinders. First, they are more compact, which makes them ideal for use in confined spaces, such as tunnels. Second, they have a longer stroke length than conventional cylinders, which means they can exert more force over a longer distance. Third, they are more resistant to buckling, which is essential for applications such as tunnel boring.
Applications of Telescopic Cylinders
Telescopic cylinders are used in a wide variety of applications, from construction and mining to transportation and manufacturing. One common use is in forklift tilt cylinders, which allow the operator to tilt the forklift's mast to pick up and transport heavy loads. Other applications include lifting and tilting platforms, drilling equipment, and dump trucks.

Using Telescopic Cylinders in Tunnel Boring Machines
Telescopic cylinders are an essential component of tunnel boring machines, providing the necessary thrust to break through rock and soil. The cylinders are typically mounted on the TBM's shield and provide the forward thrust needed to move the cutting head forward. The cylinders are also used to steer the machine and maintain its position in the tunnel.
FAQs
1. What is the maximum stroke length of telescopic cylinders?
The stroke length of telescopic cylinders can vary depending on the specific application, but some models can have a maximum stroke length of up to 30 feet.
2. Can telescopic cylinders be customized?
Yes, telescopic cylinders can be customized to meet specific application requirements. Customization options include stroke length, bore size, and mounting options.
3. What is the lifespan of a telescopic cylinder?
The lifespan of a telescopic cylinder depends on several factors, including the frequency of use, the operating conditions, and the quality of maintenance. With proper care and maintenance, a telescopic cylinder can last for many years.
