Counterbalance Valve 36188GT / 36188 – Optimized Product Page Content

🔹 Product Overview
The Counterbalance Valve with Genie part numbers 36188GT and 36188 is a critical, safety-rated hydraulic component used extensively on the major lift and extension cylinders of various Genie Boom Lifts (S and TMZ Series). This valve is non-negotiable for safe operation, performing two core functions: 1) it acts as a load-holding valve to hydraulically lock the cylinder in place, preventing the boom from drifting, creeping, or collapsing; and 2) it smoothly controls the speed of any lowering or retracting load driven by gravity, which prevents uncontrolled, dangerous “runaway” movement.
This component is essential for the safe and predictable operation of the machine’s primary movements. The part number 36188GT is the necessary replacement for addressing dangerous issues such as uncontrolled boom descent or retraction (creep), or jerky, unstable lowering movements under load.
🔹 Key Features & Benefits
✅ Load Holding Safety: Locks the hydraulic cylinder in position, eliminating drift and unintended movement.
✅ Smooth Motion Control: Controls the speed of overhauling loads, ensuring precise feathering and safe descent.
✅ Broad Boom Fitment: Essential safety component for popular Genie S-series and TMZ-series boom lifts.
✅ Direct OEM Cross-Reference: High-quality aftermarket equivalent for Genie part numbers 36188GT and 36188.
