Refuse Truck Locking Cylinder
EP-HCYY11112032 · Φ63mm · Stroke 160mm · 20 MPa · 15 kg

The hydraulic lock that holds the hopper body and tailgate firmly in position during waste collection and road transport. Without it, the loaded hopper could shift during braking or cornering — creating a safety hazard and spilling waste. The locking cylinder engages and disengages hydraulically from the cab, allowing the driver to lock the body for transport and unlock it for emptying at the transfer station.

How the Locking Cylinder Secures the Refuse Truck Body

Refuse compression truck hydraulic system

A rear-loading refuse compression truck has a hopper body that tips or lifts for emptying. During collection runs, this body must be locked rigidly to the chassis — it contains several tonnes of compressed waste, and any movement during driving creates dangerous load shift.

The locking cylinder inserts a steel locking pin or engages a latch mechanism that mechanically connects the hopper body to the chassis frame. The 160 mm stroke provides enough travel to fully engage the lock through the chassis and body alignment holes. At 20 MPa, the Φ63 bore produces approximately 62 kN of locking force — more than enough to hold the pin securely against vibration and dynamic loads during driving.

The driver operates the lock from the cab — engaging it before driving and releasing it at the disposal site. The cylinder must be reliable in all weather conditions: rain, frost, road salt, and the corrosive environment created by waste leachate. Browse the full mobile machinery hydraulic cylinder range.

Why Hydraulic Locking Instead of Mechanical Latches?

Cab-Operated Safety

The driver locks and unlocks the body without leaving the cab — eliminating the risk of being struck by the tailgate or hopper during manual latch engagement. Hydraulic operation also ensures consistent locking force every time.

Positive Force Engagement

The 62 kN hydraulic force drives the locking pin fully home — even if alignment holes are slightly misaligned from body deflection or wear. Mechanical latches rely on gravity or springs, which can fail to engage fully.

Corrosion-Resistant Operation

Mechanical latches corrode quickly in the refuse truck environment (waste acids, road salt, moisture). The hydraulic cylinder's sealed design protects the mechanism, and the hard-chrome rod resists the corrosive environment.

Frequently Asked Questions

How many locking cylinders does a refuse truck use?

Typically 2–4, depending on the body size and manufacturer. Larger rear-loaders may use 4 locking cylinders (two per side) to distribute the clamping force. Contact Korea Ever-Power with your truck model for the exact configuration.

What is the difference between the Φ63 and Φ40 bore specifications?

The Φ63 bore (160 mm stroke, 440 mm installation distance) is for larger refuse trucks with heavier body weights. The Φ40 bore (53 mm stroke, 245 mm installation distance) is for lighter vehicles or auxiliary locking positions with lower force requirements.

How often does the locking cylinder need replacement?

The locking cylinder cycles 2–4 times per collection route (lock for driving, unlock for emptying, repeat). At 1–2 routes per day, the annual cycle count is relatively low (1,000–3,000). The primary failure mode is seal degradation from exposure to waste leachate and road salt — typically after 3–5 years.

Can I order the complete refuse truck cylinder set?

Yes — locking, reverse thrust, and forward thrust cylinders can be ordered together. Browse the mobile machinery hydraulic cylinder range.

What Our Customers Say

★★★★★Apr 2026

"Replaced locking cylinders on 8 refuse trucks. The Φ63 specification locks positively every time — no more failed-to-engage warnings on the dashboard. The 15 kg weight makes field replacement straightforward."

G. O'Brien — Fleet Maintenance, Ireland

★★★★☆Oct 2025

"Good quality at approximately 40% below OEM price. The hard-chrome rod resists the corrosive refuse truck environment better than our previous aftermarket supplier. After 18 months, zero leaks."

F. Delgado — Municipal Fleet Manager, Spain
