Forklift Short Lifting Cylinder | Bore Φ75–95mm | Free-Lift Stage
Forklift Short Lifting Cylinder
Free-Lift Stage · Bore Φ75–95mm · Stroke 775–800mm
The cylinder that lets a forklift work inside shipping containers, box trucks, and low-ceiling warehouses. The short lifting cylinder raises the carriage and forks without extending the outer mast sections — keeping the overall mast height unchanged. This "free-lift" capability is what makes a triple-stage mast useful in height-restricted environments.

▲ Forklift Short Lifting Cylinder | Bore Φ75–95mm | Free-Lift StageWhat Is Free-Lift and Why Does It Matter?
On a standard duplex (two-stage) mast, the forklift must extend the outer mast section upward before the carriage can rise — increasing the overall mast height above the forklift. This is fine in open warehouses, but creates problems in height-restricted spaces: shipping containers (internal height ~2.4 m), box trucks, aircraft cargo holds, and buildings with low ceilings or overhead obstructions.
A triple-stage (triplex) mast solves this with a "free-lift" stage — an initial lifting range where the carriage rises without the outer mast sections moving at all. The short lifting cylinder provides this free-lift. It is mounted centrally in the inner mast channel and lifts the carriage through its 775–800 mm stroke before the main lifting cylinders begin extending the outer mast sections.
The result: the forklift can raise a load to approximately 1,500–1,600 mm (free-lift height, including chain multiplication) without any increase in overall mast height — allowing it to pick up and place pallets inside containers, trucks, and low-ceiling environments where a standard mast would not fit.

Short Lifting Cylinder vs Main Lifting Cylinder
Both cylinders lift the carriage — but their roles are different, and they operate in sequence:
Acts first. Raises the carriage through the free-lift range (775–800 mm stroke) without moving the outer mast. Single cylinder, mounted centrally. The mast height stays unchanged — critical in low-clearance environments.
Acts second, after the free-lift stroke is exhausted. Extends the outer mast sections upward, increasing overall mast height. Paired left/right cylinders with 1,500 mm stroke. Provides the remaining lift height for full stacking.
Available Specifications
Five specifications cover a range of forklift models with different mast channel widths and load requirements:
| No. | Bore (D) | Rod (d) | Stroke (S) | Inst. Dist. (L) | Rod Ratio | Specifications |
|---|---|---|---|---|---|---|
| 1 | Φ75 | Φ60 | 800 | 1,065 | 80.0% | Φ75×Φ60×800 |
| 2 | Φ85 | Φ70 | 777 | 1,015 | 82.4% | Φ85×Φ70×777 |
| 3 | Φ85 | Φ70 | 777 | 1,015 | 82.4% | Φ85×Φ70×777 |
| 4 | Φ95 | Φ80 | 800 | 1,065 | 84.2% | Φ95×Φ80×800 |
| 5 | Φ95 | Φ80 | 775 | 1,013 | 84.2% | Φ95×Φ80×775 |
Key Advantages
- Free-lift without mast extension — the carriage rises approximately 1,500–1,600 mm (with chain multiplication) before the outer mast sections begin to extend. This keeps the forklift's overall height constant during the initial lift range.
- 80–84% rod-to-bore ratio — the highest rod ratio in the forklift cylinder family. The thick rod provides column strength for the vertical push, while the compact bore fits inside the narrow inner mast channel of a triple-stage mast.
- Enables container and truck loading — a standard 20' or 40' shipping container has an internal height of approximately 2.39 m (standard) or 2.69 m (high-cube). Without free-lift, a forklift cannot raise or lower pallets inside the container. The short lifting cylinder makes this possible.
- ⚡ Single centrally mounted cylinder — unlike the paired main lifting cylinders, the short lifting cylinder is a single unit mounted centrally in the inner mast. This simplifies installation and reduces the number of hydraulic connections.
- Compact installation distance — 1,013–1,065 mm overall length fits within the inner mast channel height without interfering with the main lifting cylinders or the chain routing.

Frequently Asked Questions
What Our Customers Say
"We replaced short lifting cylinders on 8 forklifts with triplex masts. The Φ95 specification matched our existing mast channels perfectly. Free-lift height restored to factory spec — our forklifts can load containers again without the mast hitting the container roof."
R. Müller — Fleet Engineer, Germany
"We ordered short lifting + main lifting + tilt cylinders as a complete mast set. Having all three from Korea Ever-Power simplified procurement — one order, one shipment, one invoice. All cylinders fit without modification."
C. Park — Procurement Manager, South Korea
"Good quality at around 35% below OEM price. The 84% rod ratio concerned us initially, but the cylinder handles our 3.5-tonne loads at full free-lift height without any rod deflection. Chrome finish on the rod is smooth and even."
A. Petrov — Maintenance Supervisor, Russia
"The free-lift is essential for our cold storage operation — the warehouse ceiling is only 2.5 metres. Without the short lifting cylinder, our forklifts cannot pick from the second rack level. Korea Ever-Power delivered the Φ85 specification in 5 weeks."
M. Johansson — Warehouse Manager, Sweden
"We manage a fleet of 22 triplex-mast forklifts across 3 distribution centres. Standardised on Korea Ever-Power short lifting cylinders after testing on 2 units for 6 months. Warranty claims: zero. Now ordering for the full fleet."
L. Garcia — Fleet Director, Spain
