152301000186A Hydraulic Hoist Lifting & Float Control Valve Block for Sany SAT40C

The 152301000186A Lifting Floating Valve Block (commonly referred to in heavy machinery maintenance as the Hoisting & Float Control Valve Block) is a critical hydraulic control component designed for the cargo-body system of the Sany SAT40C articulated dump truck. During dumping operations, high-thrust hydraulic cylinders lift the heavy cargo box. However, during loaded or empty haul cycles, the dump body must rest and “float” freely on the rear frame’s rubber chassis pads. If the hydraulic hoist loop remained rigidly locked during bumpy off-road transit, the continuous ground shocks would bend the cylinder rods or crack the structural mounting brackets. The lifting-floating valve block uses an integrated electronic solenoid valve to toggle the hoist cylinders into “float mode,” allowing them to expand and compress freely with the frame twists.

This high-pressure manifold block houses the core Solenoid Valve (152301000186A001) cartridge. It is manufactured from cast iron or heavy-duty steel, designed to withstand intense hydraulic pressure surges and continuous vibration without structural distortion. We supply the fully integrated 152301000186A valve block as well as individual replacement solenoid valves, internal spools, and sealing gaskets. Both genuine Sany OEM kits and highly reliable aftermarket options are in stock for rapid international shipping.

Features & Benefits of Our Hoist Float Valve Block

• Precise Electro-Hydraulic Float Control: The high-accuracy Solenoid Valve (152301000186A001) receives electrical signals from the cab’s main control joystick, seamlessly shifting internal spools to toggle the hoist cylinders between lifting, holding, and free-floating states.
• Durable Core Protection: Protects the truck’s rear frame and hoist cylinders from heavy stress fatigue during transit by allowing the heavy cargo box to “float” dynamically over uneven ground.
• Cast-Steel Block Housing: The compact block housing is cast from high-density, low-porosity metal, machined to close tolerances to maintain tight cartridge seats and prevent internal pressure bypass leaks.

Ordering & Technical Maintenance Guidelines

1. Verify Electrical Coil and Plug Configurations: Proportional and direct-acting solenoid valves are wired to specific vehicle voltages (typically 24V) and wire-connector pin designs. Please provide your Sany SAT40C articulated dump truck’s chassis serial prefix so our technical team can verify electrical compatibility.
2. Always Replace Gaskets and O-rings: The solenoid cartridge uses high-durability elastomeric O-rings and backup seals. Always install brand-new, pre-lubricated seals whenever a cartridge is removed or replaced to prevent high-pressure external oil leaks.
3. Observe Cleanliness on Installation: High-pressure common hydraulics are highly vulnerable to particulate contamination. Keep port caps on until the exact moment of connecting the steel hoses, and clean the cartridge cavity thoroughly to prevent dirt from binding the valve plunger.
