Mile Marker HI12000 – 12000 lb. Hydraulic Winch - 75-52000C
The Mile Marker HI12000 Series Hydraulic winch is made to be permanently mounted in the front or rear of a vehicle and comes with the solenoid control valve factory mounted to the winch, allowing for a more efficient installation. Utilizing the vehicle’s power steering system as its power source ensures the HI12000 will run continuously without draining the battery.
Completely element proof construction, corrosion and water resistant, the HI12000 features two speed, free spooling, mechanical lock, an integrated solenoid valve, a ductile iron body, stainless steel tie bars and fasteners, reversible mounting on 3 sides, 100’ of steel cable, 12,000 pounds of pulling capacity and includes an illuminated joystick remote control. Requires a vehicle specific 35 Series valve adapter kit to adapt to the vehicle’s power steering pump.

What our Experts Think
-
12,000 lb pulling capacity — Strong enough for recovering large trucks, work vehicles, and heavily loaded off-road rigs.
-
Hydraulic power for continuous duty — Runs off the vehicle’s power-steering system, allowing long, repeated pulls without overheating or draining batteries.
-
Fully sealed, submersible construction — Built to withstand mud, deep water, and harsh job-site conditions.
-
Two-speed planetary gearing — Provides smooth, controlled pulling with mechanical lock and a free-spool function for fast line deployment.
-
Complete, versatile setup — Includes steel cable and roller fairlead, suitable for front or rear mounting depending on your build.
Q&A
Q: What is the pulling capacity?
A: 12,000 lbs single-line pull, ideal for heavy trucks, recovery rigs, and demanding off-road use.
Q: How is the winch powered?
A: Fully hydraulic, operating off the vehicle’s power-steering or compatible hydraulic system for continuous duty without electrical strain.
Q: What cable does it include?
A: Typically equipped with a 3/8" × 100 ft steel cable paired with a roller fairlead.
Q: What key features does it offer?
A: Two-speed operation, planetary gear train, mechanical load-holding brake, and free-spooling for quick line deployment.
Q: Is it durable and weather-resistant?
A: Yes — sealed, corrosion-resistant, and built for harsh environments including mud, water, and snow.
Q: What are the installation requirements?
A: Requires a compatible hydraulic adapter kit and proper plumbing into the vehicle’s hydraulic system.
Q: Who is this winch best suited for?
A: Tow trucks, heavy off-road vehicles, work trucks, and users needing high reliability for frequent or long-duration pulls.
Maintenance Tips
-
Inspect the winch cable regularly – look for kinks, frays, corrosion, or flattened sections; replace if any damage is present.
-
Check hydraulic lines and fittings – ensure hoses are tight, leak-free, and routed away from heat and sharp edges.
-
Verify mounting hardware – re-torque all bolts after installation and periodically, especially after heavy recovery work.
-
Keep the winch clean – remove mud, grit, and salt buildup from the drum, housing, and fairlead to prevent wear and corrosion.
-
Lubricate moving parts – apply light lubrication to fairlead rollers and pivot points to maintain smooth operation.
-
Inspect hook and recovery hardware – check for cracks, deformation, or worn latches before each use.
-
Cycle the winch regularly – spool in/out under light load to maintain hydraulic system performance and prevent sticking.
-
Monitor hydraulic fluid levels – ensure the system stays properly filled and check for leaks that may reduce pulling power.
-
Protect against weather – use a winch cover when not in service to prevent UV, moisture, and debris damage.
-
Observe rated capacity – never exceed the 12,000 lb pull rating to avoid equipment damage and safety hazards.
