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, 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.
