The HD-973PX uses multi-position safety locks spaced closely to support a wide range of parking height arrangements. Redundant anti-fall, spring-loaded safety catches help halt downward movement in the unlikely event of cable failure, while independent backup slack-cable latches and a padded trip bar with limit switch add further protection. Heavy-duty welded-steel construction, aluminum platform decking, hydraulic cylinders, 3/8-inch lifting cables and a load-displacing base structure give the HD-973PX the strength needed for demanding parking applications. Optional drive-thru ramps and 4,500-lb. air-hydraulic rolling jacks are available for expanded workflow.
