With the growing demand for wheeled excavators (referred to as “wheel excavators” for short) in urban infrastructure, road emergency repair, farmland water conservancy and other fields, the technical bottlenecks faced by hydraulic braking systems have become increasingly prominent. In the operating environment of frequent start-stop, heavy-load pressure bearing and complex road conditions, how to ensure the efficiency, safety and stability of the braking system has become a key issue in the technological development of the industry. Ningbo Flagup Hydraulic Technology Co., Ltd. has successfully broken through this bottleneck through independent research and development, leading the innovation of wheel excavator hydraulic braking technology with its excellent performance in extreme environments and high-precision braking control.
Technical Challenges Faced by Hydraulic Braking
During the high-frequency operation of wheel excavators, the hydraulic braking system faces three main technical bottlenecks: first, “poor adaptability to extreme temperature ranges”, second, “lagging response of heavy-load braking”, and third, “insufficient control precision under complex working conditions”. These problems directly affect the braking safety and operation efficiency of wheel excavators. Therefore, to break these technical barriers, innovative breakthroughs must be made in material technology, structural design, performance testing and other aspects.
Flagup’s Technological Innovation: How to Solve Wheel Excavator Braking Problems
High-Strength Alloy and Precision Machining
Flagup hydraulic brake valves adopt aviation-grade high-strength alloy materials and micron-level precision machining processes. The core valve cores and valve bodies have passed more than 100,000 pressure-resistant cycle tests and high-low temperature cycle impact tests from -40℃ to 80℃. Even in extreme environments such as severe cold frozen soil or high-temperature exposure, they can still maintain a fast braking response within 0.3 seconds, and the braking pressure fluctuation error is controlled within ±2%.
Two-Stage Pressure-Reducing Flow Channel Design
Flagup innovatively adopts the “two-stage pressure-reducing flow channel design” to optimize the flow state of hydraulic oil and reduce pressure loss. Under heavy-load working conditions, the brake pedal force is reduced by 15%, and millimetric-level brake stroke control is realized at the same time. This design effectively meets the demand for precise parking during operation in narrow spaces.
Intelligent Pressure Compensation System
This system can automatically adjust the braking pressure according to the load change of the wheel excavator. Under complex road conditions such as mountain ramps and muddy roads, the intelligent pressure compensation valve effectively avoids brake locking or skidding, greatly improving the safety of driving and operation.
Since its launch, Flagup hydraulic brake valves have carried out in-depth technical cooperation with many well-known wheel excavator enterprises such as XCMG and Liugong, and have been successfully installed on 3.5-ton to 15-ton wheel excavator equipment. They have passed the practical verification of hundreds of thousands of working hours on thousands of sets of equipment. In various complex environments such as plateaus, deserts and coastal areas, the failure rate is less than 0.5%, far exceeding the industry average.
