Elevators

Hydraulic Passenger Elevators

Proven Technology

Hydraulic elevators have been in service around the world for many decades. They use proven, oil-based lifting technology in low to mid-rise buildings (up to 6 floors) to provide a robust and reliable elevating device.

Affordability

Hydraulic elevators are relatively simple in design compared to traction elevators. This makes them a cost-effective choice when the entire product life cycle is considered—from the initial installation through to regular maintenance.

Durability

Under normal circumstances with regular preventive maintenance, many hydraulic elevators last more than 20 years before requiring major upgrades.

Serviceability

Hydraulic elevators generally have fewer parts than traction elevators, which makes them easier to maintain and service. In addition, there are fewer proprietary parts, so they can be serviced by other elevator contractors instead of the OEM.
