Product Overview

Models ED2150, ED2155, ED2250, SL3002 and EM1250 are heavy-duty hydraulic planetary reducers with 2/3-stage transmission structures, belonging to the Brevini ED/SL/EM Series. Custom configuration and production coding are available to support diverse specification variants, including different gear stages, gear ratios, output forms, parking brake setups and sealing solutions. Adopting high-precision planetary drive technology and premium hardened gear teeth plus inner gear rings that guarantee reliable operation under high torque and harsh load conditions, these reducers serve as direct aftermarket replacements for original OEM reducers with fully matched installation dimensions and interface parameters.

The Brevini ED/SL/EM Series represents premium high-efficiency planetary reducers, delivering stable high-torque output under a compact, space-saving casing. The matched hydraulic system features a standard working pressure of 350 bar, fully adapting to long-duration heavy-load operation. Deployed in severe service environments including rotary drilling, foundation piling, construction lifting and heavy engineering works, these reducers exhibit excellent load resistance and long-term operational durability. They act as the core hydraulic drive components for heavy-duty machinery such as rotary drilling rigs, piling rigs, crawler cranes, mining equipment and marine & offshore lifting facilities. Designed with standard SAE heavy-duty mounting flanges and spline connections, plus a reinforced integral housing structure, the entire series resists frequent heavy shock loads and continuous mechanical vibration, perfectly fitting the harsh operating conditions of various mobile and industrial hydraulic equipment.

This reducer range supports a wide variety of customized structural variants, including tailored gear stages, special output shafts and spline profiles purpose-built to pair with different types of hydraulic motors and integrated hydraulic transmission assemblies. Custom versions can be engineered to remove conventional intermediate connecting components, enabling direct assembly with matched hydraulic drive systems via dedicated spline and interface designs. They are ideal for hydraulic drive systems with limited installation space, or equipment adopting integrated modular and lightweight design concepts for foundation drilling machinery.

Core Advantages

Brevini ED/SL/EM Series Reducer

1. Integrated Structure Design - An Ideal Choice For Integrated Drive & Electrified Systems

Brevini ED/SL/EM Series Planetary Hydraulic Reducer adopts optimized integrated structure design, which is a dedicated configuration for integrated drive and electrified hydraulic systems:

Integrated connecting structure: Custom spline and shaft end design are adopted. External radial loads are shared by the matching hydraulic motor assembly on the user's equipment;

Direct integration with hydraulic motors & drive assemblies: The reducer can be directly flange-mounted to various fixed / variable displacement hydraulic motors without additional support bearings or couplings, perfectly matching the electro-hydraulic power module for rotary drilling rigs;

Compact overall dimension: The streamlined multi-stage planetary structure greatly shortens the overall installation size, making it particularly suitable for drilling equipment with extremely limited installation space;

Easy installation: Standard SAE heavy-duty mounting dimensions and multi-bolt fixed flange layout enable seamless matching with user equipment and ensure excellent concentricity during operation. Besides, the modular integrated design supports multiple reducers tandem installation, further expanding system configuration flexibility for foundation drilling machinery.

2. Brevini ED/SL/EM Series - High Performance Planetary Hydraulic Reducer

The Brevini ED/SL/EM Series stands for premium high-performance planetary hydraulic reducers in the product lineup:

High torque density: Delivers stable high torque output (18,000 - 45,000 Nm) within a compact housing. The matched hydraulic system features a standard continuous working pressure of 350 bar for all models;

Advanced planetary gear & housing assembly: Equipped with optimized 2/3-stage planetary transmission and reinforced hardened gear teeth & inner gear ring structure, it achieves higher mechanical efficiency and strong resistance to shock and vibration during rotary drilling operations;

High-stability gear meshing & sealing technology: Precisely machined gear sets maintain stable meshing performance with automatic wear compensation, keeps excellent transmission efficiency during long-term operation and effectively reduces power loss;

Harsh condition adaptability: Capable of working stably under rated continuous pressure and long-duration heavy load, adapting to a wide temperature range (-20°C ~ +45°C) and frequent load changes. It performs reliably on rotary drilling rigs, piling equipment and foundation machinery under severe working conditions such as dust, mud immersion and heavy vibration.
