Sistemas Hidráulicos

Unidade Móvel de Tecnologia de Estabilização da Talha HSE2-16



In mobile hydraulics, such as:

  • Wheel loaders
  • Material handling machines


The HSE2-16 is a hoist suspension unit for use in wheel loaders or similar vehicles.

The hoist stabilisation unit

HSE 2-16 reduces vehicle pitching.

The load bearing line is linked to one or several hydraulic accumulators via a control valve. The accumulator(s) act as a hydro-pneumatic spring and as such decouple the source of the oscillation from the rest of the vehicle, and therefore from the driver.

The accumulator should be sized in consultation with Hydac in order to achieve the optim um overall system


  • Higher transport and driving speeds
  • Greater handling capacity
  • More stable steering behaviour
  • Shorter braking distances
  • Greater comfort
  • Lower mechanical stresses
  • Lower downtimes
  • Compliance with Health & Safety at Work directives
  •  Accumulator pressure always at load level
  • No movement of the hoist when the suspension is connected.
