EP-CTU3150 Planetary Track Drive Gearbox
Brevini CTU3150 Compatible Replacement | EVER POWER
Cái 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 Nm 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.
Tổng quan sản phẩm
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.

Nguyên lý hoạt động
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.
Cái 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.
Lợi thế cốt lõi
| ● 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. |

Công nghệ cấu trúc và vật liệu
Vỏ được đúc chính xác từ... Gang dẻo GGG50 and machined to ISO H7 bore tolerances. Planet gears are manufactured from Thép tôi cứng bề mặt 20CrMnTi, 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.
Các kịch bản ứng dụng điển hình
| Ngành công nghiệp | Machine Type | Scenario |
|---|---|---|
| Construction | 10-18 t excavator | Track drive for continuous digging cycles on soft and hard ground. |
| Khai thác mỏ | Compact crawler loader | Low-speed high-torque traction in underground hard-rock galleries. |
| Khoan | Tracked rotary drill rig | Self-propel drive on uneven terrain; brake holds rig on slope during drilling. |
| Lâm nghiệp | Tracked harvester base | High traction torque for soft bog conditions; sealed unit protects against wood chip ingress. |
Hướng dẫn lựa chọn
- 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.
- Giao diện động cơ – SAE-B, SAE-C, or ISO flange; shaft or spline input.
- Áp suất nhả phanh – Confirm available hydraulic pressure (typically 20-35 bar).
- Ground Conditions – Wet, abrasive or chemically aggressive environments may need upgraded seal specification.

Câu hỏi thường gặp
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.
