HYDRAULIC ELEVATOR

Hydraulic Elevator

  • No machine room
  • No extra room
  • No pit
  • No shaft

Advantages:

In terms of customers:

  • A further economy is realized in the maintenance cost of the hydraulic elevator.
  • More effective building space utilization.
  • The hydraulic elevator uses about 12% less hoistway area than the traction unit since, the extra room for the counterweight is not required for hydraulic units.
  • Since the hydraulic elevator imposes no vertical loads on the building structure, column sizes can be reduced significantly in the hoistway area.
  • Machine room location can be very flexible.
  • It can be easily applied to the buildings without a shaft.
  • It is also suitable for installing in old buildings, where structural reinforcements to support the overhead loads imposed by traction elevator equipment would be costly and impractical.
  • Hydraulic elevators are well suited for installations where future floors may be added to the building.
  • High reliability on failure free operation.
  • Involves no experts for rescue operations. Most emergency measures can be taken without entering the shaft or climbing to the top floor. Elevator controls can be adjusted without working in the shaft.
  • Single time 3 phase power is used in Up direction only, for Down 1 phase power is more than enough. The limited amount of heat generated by the hydraulic power unit during down travel can serve to temper the lower temperature in the basement of buildings, in which case there is potentially no waste of energy.
