Cantilever Roped Hydraulic Elevators
The cantilever roped hydraulic elevator is a holeless design where wire ropes are utilized in conjunction with a hydraulic jack. The elevator car is lifted with a 2:1 ratio which means that for every foot that the hydraulic jack rises, the elevator car rises two feet.
- No jack hole drilling is required which reduces cost and eliminates the possibility of ground contamination.
- Travel can be as great as 100 feet without drilling for a hydraulic jack.
- Accommodates front and side openings.
- No extensive pit or overhead clearance is required.
- Because the rail and hydraulic jack equipment is located on the side or rear of the elevator, additional hoistway space is required.
- Since the rail and rail brackets are mounted to one wall, additional rail forces are applied.
- Requires more installation time than a conventional installation.
