INI Hydraulic Winch Project Introduction

INI Hydraulic Winch Project Introduction High-Performance 59-Ton Hydraulic Winch for Oilfield Applications

Welcome to the official project introduction of INI Hydraulics, a leading innovator in hydraulic systems with 28 years of industry expertise. This comprehensive overview presents our groundbreaking development: a high-capacity, dual-mode hydraulic winch engineered specifically for heavy-duty oilfield clearance and towing operations.

Designed to meet the rigorous demands of real-world field conditions — and inspired by the performance standards of globally recognized models such as the Breden winch (USA) — this project marks a milestone as China’s first independently developed hydraulic winch of its kind, setting new benchmarks in power, safety, and reliability.

Project Overview: Meeting Critical Industry Needs

In response to customer requirements for safe and efficient heavy-equipment recovery in remote oilfields, INI Hydraulics has successfully developed a customized high-torque hydraulic winch with:

- Maximum Pulling Force:

- 59 tons (heavy load mode)

- 29 tons (light load mode)

- Braking Capacity: 7.5 tons – ensuring secure holding under extreme tension

- Compliance: Fully tested and certified to meet CE standards

- Application: Ideal for oilfield tow trucks, emergency recovery, drilling rig relocation, and offshore support operations

This innovation underscores our commitment to delivering professional, efficient, and fully customized hydraulic solutions that solve complex engineering challenges.

Key Technical Highlights & Engineering Innovations

1. Advanced Power Transmission & Maintenance-Friendly Design

At the heart of the system lies a hydraulic cylinder-driven tooth clutch combined with a drum-type brake mechanism, offering:

- Reliable torque transmission under high-impact loads

- Rapid free-spool release function — significantly improving rope deployment speed and operational efficiency

- Easy maintenance access due to modular design and proven component layout

- Optimized for durability in harsh environments including deserts, tundras, and offshore platforms

Inspired by global best practices but refined through local application insights, this transmission system balances robustness with user-centric functionality.

2. Dual Braking System: Safety Through Redundancy

Safety is non-negotiable in heavy-load scenarios. Our winch integrates two independent braking mechanisms working in synergy:

Brake Type	Function	Key Benefits
Normally Closed Disc Brake	Primary braking via hydraulic control	Compact structure, smooth engagement, fast response time
Drum Band Brake	Mechanical backup acting directly on drum	Provides auxiliary braking, impact absorption, and fail-safe protection during sudden load shifts

✅ Friction parameters and spring forces are precisely calculated using finite element analysis (FEA), ensuring consistent, reliable stopping power even after prolonged use.

3. Robust Structural Components & Precision Engineering

Every structural element is designed for maximum strength-to-weight ratio and long-term performance:

▶️ Reinforced Rack Structure

- Fabricated from high-strength alloy steel plates via full-welded construction

- Resists deformation under lateral and vertical stress

- Integrated mounting interface compatible with standard oilfield tractor chassis

▶️ Optimized Drum Design

- Scientifically balanced diameter and wall thickness

- Maximizes rope capacity while minimizing deformation risk under torsional load

- Precision-machined grooves ensure uniform cable spooling and reduce wear

▶️ High-Efficiency Powertrain

- High-speed variable displacement motor enables adjustable pulling speed based on load demand

- Multi-stage planetary reducer delivers exceptional torque multiplication

- Torque transmitted via spline shaft connection for enhanced durability and alignment accuracy

4. Core Technology & In-House Quality Control

We maintain strict control over critical manufacturing processes to guarantee product excellence:

- All key gears and shafts are produced in-house, eliminating dependency on third-party suppliers

- Production workflow includes:

- Normalizing → Hobbing → Carburizing & Quenching → Grinding

- Result: Components achieve:

- Surface hardness up to HRC 58–62

- Superior wear resistance

- Extended service life under continuous duty cycles

Design Validation Process:

- Full 3D modeling and digital simulation used throughout R&D phase

- Interference checks, motion analysis, and thermal performance validated before prototyping

- Ensures seamless assembly and trouble-free field operation

5. Rigorous Testing & Performance Verification

Before delivery, each unit undergoes a series of comprehensive test protocols to validate performance, safety, and compliance:

Test Type	Conditions	Results Achieved
Rated Load Test	Continuous operation at 59T / 29T	Stable temperature rise, no leakage
Overload Test (125%)	Short-duration peak load testing	No permanent deformation or structural failure
Dynamic Braking Test	Sudden stop under tension	Immediate lock-up, no slippage
Endurance Run	Simulated multi-cycle usage	Smooth operation, minimal noise/vibration

✔️ All test data recorded and archived

✔️ Final products comply with

ISO 4499, API 7K, and CE Machinery Directive
