The Blackout Kit from Challenger Lifts is designed for use with two-post lift models so facilities can manually lower a lift during any loss of electricity. It should only be operated by properly trained technicians. The lift prep kit includes hoses, connectors, a valve, and quick disconnects that attach directly to each lift. Additionally, a pump kit is required for operation. The pump kit contains a high-pressure portable manual hand pump, attachment hoses, hydraulic connectors, a high-pressure flow control device, and a tote bag.
