Three-High Parking Lift System Description System

Description

The Harding Steel Three-High parking system is a 4-post integrated parking lift designed for rugged indoor or outdoor operation. Each system may be configured as a stand-alone lift or combined into rows of lifts, with each pair of machines sharing a common set of posts. Each parking level of the lift is an all-steel platform that will accommodate vehicles weighing up to 6000 pounds with overall heights of approximately 75”. Each vehicle platform is raised and lowered by a series of cables attached to the four corners of each platform. A hydraulic cylinder on each machine controls the raising and lowering of the platforms. Lifts are operated by a trained attendant who must be present at the control switch of each lift during operation. Lifts are equipped with steel locking mechanisms that provide safety to both vehicles and personnel.

Hydraulic Power System

Lifts are powered by an integrated power pack that consists of an electrical control panel, hydraulic pump motor, and hydraulic fluid tank. Power packs are sized to the specific application. Each power pack can operate up to 20 lifts depending on configuration, layout, and other technical factors. Power pack units each require their own dedicated 220V, 30 amp, 3-phase power circuit. Fluid tanks are equipped with electric heaters.

Applications

Three-High lifts are ideal for applications that require high density vehicle parking and storage. These lifts are employed all over the world in applications that include commercial parking, retail auto dealerships, classic car storage, residential parking, office parking, rental car agencies, and auto repair/service.

  • Commercial parking.
  • Vehicle storage
  • Auto retail and service
  • Residential - multi family
  • High security environments
  • Rental car agencies

Capacity

The maximum lifting capacity is twelve thousand (12,000) pounds. Platforms are rated at six thousand (6,000) pounds each.

Site requirements

Lifts can be installed as single units, or in rows, sharing common posts between units. – Surface must be level to within 2 inches per 8 feet (side-to-side or front-to-back). – Surface under lifts should be standard commercial grade, 3000 psi reinforced concrete at least 6” in depth. – Pier footers may be constructed in lieu of full concrete pads (see manufacturer for specifications) – Lifts will be firmly bolted to concrete pad or footers – Drainage should be such that standing water is eliminated under lift platforms – Turning radius in front of machines no less than 20’ (22’ recommended).

Clearances

Clear ceiling height: 22’ 0” minimum – Distance at rear of lifts to nearest wall or obstruction: 36” – Distance between two rows of lifts: 60-72”.

Power requirements

220V, 30 amp, 3-phase for each hydraulic power pack unit – Each power pack unit operates up to 20 lifts depending on configuration and layout – Individual lifts are operated by 24 VDC (low voltage) – Power pack units include an internal heater

Loadings

There are no uplifting loads on the structure. All loading is downward and the center of gravity is located within the lift structure. Base Plate loading is below AISC allowable standards. When operated at full capacity as a stand-alone unit, the base plate loading is 17 psi (4284 lbs on base plate). When operated as a double unit is a row, the base plate loading is 26 psi (6552 lbs on base plate)

All specifications are subject to change and must be reviewed for every installation
