The PL6000DCX includes manual safety locks to hold the platform securely in place, electric key-switch control for security, automatic shut-off when the operator releases the switch, manual safety lock release, hydraulic overload protection, and maintenance-free composite carriage bearings. These systems are designed to keep parking lift operation controlled and dependable in real-world use. When one vehicle is parked above another, safety and platform control are not bonus features. They are the reason the lift belongs in serious parking applications.
