The HDS-18EA includes spring-loaded automatic safety locks, multiple adjustable locking positions, and a push-button pneumatic lock release for efficient operation. A secondary lock system stays on guard for cable slack, while an integrated hydraulic flow restrictor helps support safe, controlled lowering in the unlikely event of hydraulic failure. A single hydraulic under-runway cylinder, maintenance-free power system, conveniently located controls, durable powder-coat finish, matte-finish runways, and 12-inch by 12-inch base plates round out a heavy-duty alignment lift built for commercial confidence. Optional rolling jacks can expand the system for wheel, brake, and suspension service.
