Now featuring Will, Jazz, Geoffrey, Aunt Viv, and even a little Ashley energy.)
Now this is a story all about how
Your lifting game got flipped-turned upside down—
So sit right there, grab a wrench, don’t run,
We’ll tell you how to pick a locknut cylinder that weighs a ton.
**🎤 1️⃣ What’s a Locknut Cylinder?
(AKA: The Geoffrey Butler of Lifting Gear)**
Enerpac locknut cylinders are the calm, refined, “I’ve got this handled” members of the hydraulic family.
They lift BIG loads—then lock them in place mechanically.
Think of the locknut like Geoffrey:
✔ dependable
✔ elegant
✔ absolutely not letting anything fall on his watch
Perfect for:
Long-duration lifting
Bridge & structural support
Machine alignment
Holding loads safely even when pressure is removed
If you need the “responsible adult” of cylinders, this is the one.
**🎤 2️⃣ Why Go Locknut?
(Because You Want Control Like Aunt Viv, Not Chaos Like Jazz.)**
Enerpac locknut cylinders offer:
50 to 1,000+ tons of power
Mechanical load holding
High-strength threaded locknut for safety
The ability to hold a lift longer than it took Will to get out of trouble
Aunt Viv would approve:
✔ stable
✔ strong
✔ impossible to argue with
Jazz would NOT approve:
✘ cannot be thrown out the house
✘ cannot “wing it”
✘ requires actual specs and reading
**🎤 3️⃣ Picking Your Tonnage
(If Will Had This Kind of Strength, He Wouldn’t Need Uncle Phil.)**
Let’s keep it real:
✔ Find the load weight
✔ Divide by number of lift points
✔ Add 20–50% safety factor
✔ Then consider going up a size
Enerpac locknut models include:
CLP Series: Small, compact brutes
CLL Series: High-tonnage giants
Many running well into the 1,000+ ton range
If the load is heavy enough to flatten Jazz’s hat, pick a bigger one.
🎤 4️⃣ Stroke Length: The “How High You Go” Question
Locknut cylinders come in strokes like:
50 mm
100 mm
150 mm
200–250+ mm for larger models
Choose based on:
Clearance
Cribbing height
How much drama you want in your lift
Ashley: “Pick the right stroke so you don’t have to do it twice.”
Will: “I don’t need instructions!”
Uncle Phil: “YES. YOU. DO.”
**🎤 5️⃣ Single-Acting
(Who’s Running the Show?)**
Single-Acting (Gravity or Load Return)
Pushes up
Comes down gently
Simple
Great for long-duration holding
If your lift needs coordination like a Banks family dinner, choose double-acting.
**🎤 6️⃣ Pumps: Choose Wisely
(You Need More Power Than Will’s Boom Box)**
Locknut cylinders require pumps rated 10,000 psi and capable of moving LARGE oil volumes.
Electric Pumps
Ideal for high-tonnage locknut cylinders
Smooth, controlled, powerful
Basically the “Aunt Viv” of pumps
Air Pumps
Practical
Workhorses
Geoffrey approved
Hand Pumps
Use only if you want triceps like Uncle Phil and regrets like Will sneaking in past curfew.
Spec Fact:
Oil volume can run from 500 cc to 12,000+ cc, so choose a pump that won’t cry.
🎤 7️⃣ Accessories — Because No Sitcom Works Without a Supporting Cast
High-pressure hoses (10,000 psi)
Tilt saddles for uneven surfaces
Pressure gauges
Steel or hardwood cribbing
Manifolds for multi-point lifts
Couplers that ACTUALLY match
Think of these as your Jazz, Hilary, and Ashley:
They may not star in the lift, but you absolutely need them.
🎤 8️⃣ The Fresh-Prince Certified Checklist
✔ Load weight known
✔ Tonnage selected (no winging it like Will)
✔ Locknut required for holding
✔ Stroke long enough for cribbing
✔ Pump matched to oil volume
✔ 10k psi hoses + couplers
✔ Cribbing strong enough for Uncle Phil to sit on
✔ Manufacturer specs reviewed (YES, Jeffrey checked them twice)
If you checked at least 5, you’re lift-ready.
