ESCO 10809 100 Ton Safety Locking Collar Cylinder Jack for Heavy Lifting and OTR/Mining Applications
The ESCO 10809 is a professional-grade 100 ton (200,000 lb) single acting aluminum cylinder jack engineered for heavy lifting operations in OTR, mining, construction, and industrial environments. Featuring a built-in safety locking collar for mechanical load holding, this jack doubles as its own support stand - helping you comply with OSHA regulation 29CFR1926.305. With a 6" stroke, a collapsed height of just 13.37", and a total weight of only 66 lbs, the 10809 delivers massive lifting power in a compact, portable package. Compatible with any 10,000 PSI hydraulic pump and backed by ESCO's 1-year manufacturer warranty.
ESCO 10809 Features
Safety Locking Collar for Mechanical Load Holding
The integrated locking collar threads down onto the fully extended piston rod to mechanically hold the load in place. This eliminates reliance on hydraulic pressure alone and allows the jack to function as its own self-contained support stand. This critical safety feature aids in complying with OSHA regulation 29CFR1926.305, making it ideal for sustained heavy lifting operations.
Heavy Duty Aluminum Construction
Built from high-strength aluminum, the ESCO 10809 delivers 100 tons of lifting capacity while weighing just 66 lbs (30 kg). This is a fraction of the weight of comparable steel cylinders, reducing operator fatigue and making it far easier to transport and position on the job site without sacrificing durability or performance.
High Flow Quick Connect Coupler
The factory-installed high flow quick connect coupler provides fast, reliable connections to any 10,000 PSI compatible hydraulic pump. The coupler comes pre-assembled with a valve for immediate use, and a protective rubber dust cap is included to keep the port clean when the jack is not in service.
Overflow Port Stroke Limiter
An integrated overflow port functions as a built-in stroke limiter, preventing the piston rod from extending beyond its safe 6" stroke range. This protects the internal seals and components from damage caused by over-extension, extending the service life of the cylinder and reducing the risk of equipment failure under load.
Compact and Portable Design
With a collapsed height of just 13.37" and an outside diameter of 7.44", the 10809 fits into tight work spaces where larger jacks cannot. The built-in carrying handle allows a single operator to easily position and reposition the cylinder, making it highly practical for field service and mobile operations.
Spring Return with Stop Ring
The single acting design features an internal spring return mechanism that automatically retracts the piston rod when hydraulic pressure is released. A precision stop ring provides stroke restriction for added stability and consistent operation throughout the cylinder's working range.
ESCO 10809 Applications

ESCO 10809 Setup and Operation
Hydraulic Pump Requirements
Compatibility: Requires a 10,000 PSI rated hydraulic pump with release valve or 3-way valve (pump sold separately). Use only ESCO oil or other approved hydraulic oil. Connect the pump to the cylinder using a single hose and hand-tighten all couplers before operation.
Pre-Use Inspection
Before every use: Visually inspect the cylinder, coupler, port threads, and hose for any signs of damage, leaks, or missing parts. If any damage is found, do not operate the cylinder and contact an authorized ESCO Service Center. Always use a saddle on the piston rod to protect the rod surface during lifting.
Operating the Locking Collar
To hold a load: Operate the hydraulic pump to extend the piston rod. Once at the desired height, rotate the locking collar clockwise until it contacts the top of the cylinder body. To release: Rotate the locking collar counterclockwise until it clears the cylinder. Then release hydraulic pressure to retract the piston rod.
Safety and Storage
Always wear safety glasses, helmet, and appropriate PPE during operation. Never exceed the 100 ton rated capacity or apply unbalanced or off-center loads. After use, fully retract the piston rod, disconnect the hose, and cover the coupler with the rubber dust cap. Store in a clean, ventilated, moisture-free environment. Do not operate in temperatures above 150F (65C).

ESCO 10809 FAQ
What is the lifting capacity of the ESCO 10809?
The ESCO 10809 has a maximum lifting capacity of 100 tons (200,000 lbs) at a maximum operating pressure of 10,000 PSI. Never exceed the rated capacity, as overloading can cause equipment failure and serious injury.
What is the height range of the ESCO 10809?
The collapsed (minimum) height is 13.37" (339 mm) and the fully extended (maximum) height is 19.60" (497 mm), providing a usable stroke of 6" (152 mm). The outside diameter is 7.44" (188 mm).
What hydraulic pump do I need for this cylinder jack?
The ESCO 10809 requires a 10,000 PSI rated hydraulic pump (sold separately). It is compatible with any standard 10,000 PSI pump equipped with a release valve or 3-way valve. Connect the pump using a single hose and hand-tighten all couplers before use. Use only ESCO oil or other approved hydraulic oil.
How does the safety locking collar work?
Once the piston rod is extended to the desired height, rotate the locking collar clockwise until it seats against the top of the cylinder body. This mechanically locks the load in place without relying on hydraulic pressure, allowing the jack to act as its own support stand. To release, rotate the collar counterclockwise until it clears the cylinder, then release hydraulic pressure to retract the piston.
What does the ESCO warranty cover?
ESCO provides a 1-year limited warranty covering defects in material and workmanship from the date of shipment to the end user. The warranty requires that the product be used in accordance with ESCO's operating instructions and maintenance guidelines. ESCO offers guaranteed 1-day turnaround repair service at their Brooksville, Florida facility and through 50+ authorized service centers across the US and Canada.

The ESCO 10809 comes with the 100 ton cylinder jack body, a pre-assembled high flow quick connect coupler with valve, the locking collar, a saddle with mounting bolts, a carrying handle, a rubber dust cap, and the operation manual with parts list. A hydraulic pump, hydraulic hose, and hydraulic oil are not included and must be purchased separately.
How is the ESCO 10809 shipped?
The ESCO 10809 ships free via ground shipping to commercial addresses in the 48 contiguous United States. The unit weighs 66 lbs and is delivered curbside. Estimated delivery time is approximately 10 business days (5 days processing + 5 days transit). Always inspect the package for damage before signing the delivery receipt.
Does this jack comply with OSHA regulations?
Yes. The ESCO 10809's integrated locking collar allows the jack to function as its own self-contained support stand, aiding in compliance with OSHA regulation 29CFR1926.305. This regulation addresses the use of mechanical equipment for lifting and requires that loads be properly supported. The locking collar provides mechanical load holding independent of hydraulic pressure.
What type of maintenance does the ESCO 10809 require?
Always use clean ESCO oil or approved hydraulic oil. Keep the cylinder and coupler clean at all times and use the dust cap when not in service. After each use, fully retract the piston rod, disconnect the hose, and store the unit in a clean, ventilated, moisture-free environment. Do not operate in temperatures above 150F (65C). Inspect the cylinder, coupler, and hose before every use. Repairs should only be performed by qualified operators or authorized ESCO Service Centers.
How does the ESCO 10809 compare to the ESCO 10808?
The ESCO 10808 and 10809 share the same aluminum locking collar cylinder design and use the same manual and parts list. The primary difference is lifting capacity - the 10808 is rated for a lower tonnage. Both models feature the safety locking collar, spring return, carrying handle, and high flow quick connect coupler. Choose the 10809 when your application requires 100 ton lifting capacity.
Can I use this jack without a locking collar?
While the jack can lift loads hydraulically without engaging the locking collar, ESCO strongly recommends always using the locking collar when holding a load for any sustained period. The cylinder is a load lifting device - the locking collar is what makes it a load holding device. Never work under a load supported only by hydraulic pressure without mechanical support.
What troubleshooting steps should I take if the cylinder will not extend?
Check the following: ensure the pump release valve is fully tightened, verify all couplers are hand-tightened securely, confirm the oil level in the pump reservoir is adequate, and verify the pump and valve are functioning properly. If the cylinder still does not extend, check for overloading beyond the 100 ton capacity or potential piston rod binding due to dirt or damage. Contact an authorized ESCO Service Center if the issue persists.
