EP-CTU3150 Planetary Track Drive Gearbox
Brevini CTU3150 Compatible Replacement | EVER POWER
The EP-CTU3150 is EVER POWER’s precision-built planetary track drive gearbox, engineered as a direct replacement for the Brevini riduttori CTU3150. Delivering 31 500 Нм output torque within a compact, flange-mounted housing, this unit keeps excavators, crawler cranes and track-type construction machines moving reliably in the toughest job-site conditions.
Өнімге шолу
The EP-CTU3150 serves construction, mining, drilling and port-handling industries wherever compact track drives are required. Its sealed, oil-bath lubricated planetary stages provide maintenance-free operation across extended service intervals, while the integrated multi-disc spring brake ensures the machine holds position on slopes whenever the hydraulic motor is de-energised.
Key highlights: 31,500 Nm rated output torque, 2-stage planetary reduction, SAE-B/ISO motor flange, spring-applied failsafe brake, IP68 sealing.

Жұмыс принципі
The EP-CTU3150 uses a two-stage epicyclic (planetary) arrangement. High-speed, low-torque input from the hydraulic travel motor enters the first-stage sun gear. Multiple planet gears orbit the sun and react against a fixed ring gear, multiplying torque at the first-stage planet carrier. That carrier becomes the input shaft to the second stage, providing a final cumulative reduction of up to 80:1.
The integrated spring-applied, hydraulically released multi-disc brake engages automatically whenever hydraulic pressure is removed – either by operator command or in the event of a system fault – preventing uncontrolled machine movement on gradients.
Негізгі артықшылықтары
| ● High Torque Density 31,500 Nm in a compact flanged body – fits original machine envelope without modification. |
● IP68 Sealed Fully submerged-capable sealing handles deep trench work, river crossings and pressure wash cycles. |
| ● Failsafe Spring Brake Spring-applied brake activates on power loss, satisfying slope-hold requirements on grades up to 35 deg. |
● Long Service Intervals Oil-bath lubrication and sealed housing deliver 2,000+ hour oil change intervals. |
| ● Drop-In Replacement Mounting dimensions match Brevini CTU3150 – no machine frame modification required for retrofit. |

Құрылым және материал технологиясы
The housing is precision-cast from GGG50 созылғыш темір and machined to ISO H7 bore tolerances. Planet gears are manufactured from 20CrMnTi корпусты қатайтатын болат, carburised and ground to DIN 5 accuracy. The output bearing is a crossed-roller slewing ring designed to handle combined axial, radial and moment loads from the track chain and idler tension. All O-ring face seals are NBR/FKM compound, rated for continuous operation in hydraulic oil, muddy water and diesel-contaminated environments.
Әдеттегі қолдану сценарийлері
| Өнеркәсіп | Машина түрі | Scenario |
|---|---|---|
| Құрылыс | 10-18 t excavator | Track drive for continuous digging cycles on soft and hard ground. |
| Тау-кен жұмыстары | Compact crawler loader | Low-speed high-torque traction in underground hard-rock galleries. |
| Бұрғылау | Tracked rotary drill rig | Self-propel drive on uneven terrain; brake holds rig on slope during drilling. |
| Орман шаруашылығы | Tracked harvester base | High traction torque for soft bog conditions; sealed unit protects against wood chip ingress. |
Таңдау бойынша нұсқаулық
- Machine Operating Weight (t) – Determines required drawbar pull and hence output torque.
- Travel Speed (km/h) – Defines required ratio given motor displacement and sprocket pitch diameter.
- Қозғалтқыш интерфейсі – SAE-B, SAE-C, or ISO flange; shaft or spline input.
- Тежегіштің босату қысымы – Confirm available hydraulic pressure (typically 20-35 bar).
- Ground Conditions – Wet, abrasive or chemically aggressive environments may need upgraded seal specification.

Жиі қойылатын сұрақтар
Q: Is the EP-CTU3150 a genuine Brevini product?
A: No. It is an independently designed EVER POWER product compatible with the Brevini CTU3150. The Brevini model number is used only for cross-reference.
Q: What hydraulic motor displacement is compatible?
A: The SAE-B/C flange accepts most 55-110 cc/rev piston and gear motors. Confirm your motor shaft diameter and key specification at order.
Q: Is the brake spring force adjustable?
A: No – brake spring preload is factory-set per the rated static holding torque. Brake release pressure is adjustable at the machine hydraulic circuit.
