103137 + 107271 Manual Descent Block And Valve (Used)
Item Description: Emergency Manual Descent Block Assembly
Part Numbers Included: 103137 (Needle Block) + 107271 (Manual Descent Pull Valve)
Condition: Used
Manufacturer: Skyjack
Category: Hydraulic Safety / Emergency Lowering System
Product Overview
This is a genuine Skyjack Emergency Manual Descent Block Assembly, combining the 103137 Needle Block Valve and the 107271 Manual Descent Pull Valve. This assembly is a critical redundant safety system found on Skyjack aerial work platforms, most notably across their popular scissor lift lines (such as the SJIII 3219, 3226, 4626, and rough terrain models).
This system allows operators or ground crew to safely lower the aerial platform in the event of a total electrical failure, dead battery, or main hydraulic pump malfunction. By pulling the integrated cable mechanism attached to this valve, hydraulic fluid is safely bypassed back to the reservoir, allowing gravity to lower the platform at a controlled speed.
