In the field of hydraulic cylinders, telescopic cylinders stand out for their ability to offer long strokes while maintaining a compact size. This type of cylinder is particularly appreciated for its versatility and power, making it ideal for a wide range of industrial and mobile applications.

How telescopic hydraulic cylinders work

Unlike standard hydraulic cylinders, which use a single piston, telescopic cylinders incorporate several nested pistons. This system makes it possible to considerably extend the cylinder stroke without increasing its overall length. When the cylinder is extended, the pistons extend in succession, increasing the effective stroke.

Types of telescopic hydraulic cylinders

Hydraulic telescopic cylinders come in several types, depending on their construction and characteristics:

  • Single-acting telescopic cylinder: This type of cylinder uses a single chamber and a single stroke, generally to push a load in one direction.
  • Double-acting telescopic cylinder: This type of cylinder uses two chambers and two strokes, enabling a load to be pushed and pulled in both directions.
  • Multi-stage telescopic cylinder: This type of cylinder incorporates several piston stages, offering even longer strokes for specific applications.

Advantages of telescopic hydraulic cylinders

Telescopic hydraulic cylinders offer many advantages that make them attractive for a variety of applications:

  • Extended stroke: They offer much longer strokes than standard cylinders, enabling loads to be moved over greater distances.
  • Space-saving: Their compact design means they can be integrated into tight spaces where standard cylinders would not fit.
  • Versatility: they can be used in a wide range of applications, from construction equipment to industrial machinery and agricultural equipment.
  • High force: They can generate large forces to move heavy loads.
  • Precise control: Cylinder speed and force can be precisely controlled.

Applications for telescopic hydraulic cylinders

Telescopic hydraulic cylinders are used in a wide range of applications where their extended stroke and compactness are major advantages, including :

  • Construction: To control hydraulic excavators, cranes and wheel loaders.
  • Industry: For hydraulic presses, stamping machines and automation systems.
  • Handling: To power forklift trucks, stackers and palletizers.
