Manufacture and sale of Hydraulic Locking Unit

Hydraulic Locking Unit

  • Simple piston rod locking
  • Economical solution for multiple cylinders
  • High locking forces due to the pressure amplification
  •  
  • Piston rods can be locked hydraulically by locking up the oil, which is under pressure, in the cylinder. In this condition, the cylinder is firmly locked as long as there is not more force guided into the cylinder than the locked, pressurized hydraulic fluid can withstand. In case the force limit is exceeded, the piston rod leaves its’ position due to the slight compressibility of the hydraulic fluid.
  •  
  • The reinforced hydraulic locking unit HLU makes it possible to hydraulically lock the piston rods of various hydraulic cylinders, regardless of size, type, or stroke, and to simultaneously increase the locking forces significantly as opposed to the forces limited by the system pressure. No additional controls or appliances are necessary for this purpose.
  •  
  • The piping effort remains almost the same compared to the standard, because the locking unit is simply being interposed.

Die-Casting Industry

Die-Casting Industry

  • Hydraulic cylinders in the die casting industry work under most difficult conditions in extreme surroundings such as tight spaces and high degrees of pollution and high temperatures. Manufacturers of dies, moulds and tools request customized technology and tailored hydraulic cylinders. To fulfill these requests we draw from our vast experience in die casting technology to develop and improve our products. We do not only focus on constructing the cylinder with its function but take a close look at the environment with our customer. Apart from the parameters of the hydraulic circuit finding the balance with other components plays a significant part.
