ROPED HYDRAULIC ELEVATOR


ROPED HYDRAULIC ELEVATOR:
Hydraulic elevators use proven hydraulic lifting technology in low to mid-rise buildings (up to 6 floors) to provide a robust and reliable elevator. They are simple in design & cost-effective to install & maintain. A well-maintained hydraulic elevator lasts longer than 20 years before any major modernization requirement. They are extensively used in Malls, Plazas, Apartments, Parking Garages, Hospitals, Schools, Religious places, other ICI buildings etc.

This is a hole-less design and therefore there is no risk of oil contamination in the ground as well as no additional cost of drilling the hole. Roped design allows the elevator cab to travel double the distance for the same movement of the hydraulic cylinders, thus limiting the Pit Depth & Overhead Height.
 

1.    Dual Cylinder type:
This design is with two hydraulic cylinders to lift the elevator cab and provides very high structural stability. This design is with wire ropes in conjunction with two hydraulic cylinders to lift the car at a 1:2 ratio. For every metre of cylinder rise, the elevator cab rises two metre. Two cylinders, one on each side of the car, provides maximum structural stability.

2. Single Cantilevered Cylinder type:
This design is useful for adding an elevator in a 3 to 6 stories existing building with limited foot print space for the hoistway shaft, where a LULA (Limited Use Limited Application) Elevator can’t provide the required Cab Size or Duty Load (Capacity & Speed). A Single Cantilevered Cylinder Passenger Elevator deign requires customization and the load carrying capacity is limited to 909 Kg (2,000 lb). After carefully considering various parameters like required elevator Cab Size, Speed, Total Travel, Number of Floors, Available Pit depth, Overhead height, Hoistway Shaft size & Construction Type etc., it can be determined if a single cylinder design would be suitable or not. This design uses one hydraulic cylinder to lift the elevator cab at a 1:2 ratio.

 

Based on above this design is suitable for:

  • Lower capacity, limited to approximate 909 kg (2,000 lb)
  • Cab size larger than a LULA Elevator but smaller than for a 1136 Kg (2,500 lb) passenger elevator
  • Fits in a smaller shaft space, as compared to a 1136 Kg (2,500 lb) passenger elevator
  • The cantilevered hydraulic cylinder can be mounted on any of the side shaft wall or can be mounted to the rear shaft wall.
