801541016 XCMG GR2605 motor grader handle

The XCMG GR2605 grader 801541016 handle is a key control component for the machine’s operation. Manufactured strictly according to XCMG’s original design standards, GB/T 25684.8 grader safety requirements, and ergonomic specifications for construction machinery control components, it is specifically customized for the GR2605 grader’s core operating functions such as blade lifting, tilting, steering, and ripper movement. It is perfectly suited for high-frequency operation, intense vibration, and dusty extreme environments such as highway construction and maintenance, airport runway grading, open-pit mine stripping, and large-scale water conservancy earthwork filling. As the operator’s “work command executor,” it integrates precise control, comfortable grip, and wear-resistant protection. It allows for stepless adjustment and instant response of operating actions, reducing operator fatigue and avoiding operational errors caused by control delays or jamming. It is a high-quality original factory replacement part for GR2605 grader handles that have suffered wear, reset failure, excessive transmission clearance, or seal failure, eliminating the need for piecemeal parts.

This control handle features an ergonomic grip design, made of oil-resistant and non-slip TPR soft rubber with a Shore hardness of 45-50HA. The surface has a biomimetic non-slip texture, conforming to the curve of the palm and distributing pressure during prolonged operation, allowing for precise control even when wearing gloves. The handle is 120mm long and 32mm in diameter, accommodating most operators’ hand sizes, ensuring no significant fatigue even after 8 hours of continuous work. The handle and control lever are integrally injection molded, with a connection strength ≥500N, ensuring no loosening or detachment risk under 25g peak vibration conditions.

The core control system employs a precision transmission structure: the control lever is machined from 45# tempered steel, with a chrome-plated anti-corrosion treatment, a hardness ≥HRC35, and a straightness error ≤0.1mm/m. It supports stepless swing of ±30° forward/backward and ±25° left/right, with uniform swing resistance (5-8N) and no jamming or idle stroke. It features a built-in high-elasticity manganese steel return spring with a return accuracy ≤±0.5°, ensuring rapid return to the neutral position after operation and preventing malfunctions. Depending on the configuration, it is available in two transmission types: electric and hydraulic. The electric type is equipped with a high-precision Hall sensor with a signal response time ≤10ms and an output signal linearity ≥0.99, suitable for electronic control systems. The hydraulic type is equipped with a miniature precision hydraulic valve with a flow control accuracy of ±2% and a pressure loss ≤0.3MPa, suitable for hydraulic control systems.

The handle protection system features a dual-sealed dustproof design: the connection between the top grip and the control stick is equipped with a nitrile rubber (NBR) seal with an IP65 protection rating, effectively preventing dust, oil, and mud from entering the internal transmission mechanism or circuitry, avoiding rust, jamming, and short circuits; the bottom mounting base is equipped with a metal dust cover, further isolating large dust particles and foreign objects, while also absorbing some operational vibrations, improving operational stability; the seals have a temperature resistance range of -40℃ to 120℃, and will not harden or crack during long-term outdoor use, ensuring long-lasting and stable sealing performance.

The product’s mounting holes, interface specifications, signal protocols, and hydraulic interfaces are all precisely matched 1:1 to the XCMG GR2605 original vehicle control system, with a hole tolerance of ±0.03mm. The electric control handle wiring harness uses the original factory standardized waterproof plug, and the hydraulic handle interface conforms to the SAE standard. No additional wiring, conduit modification, or debugging is required, and it can be directly connected to the original vehicle control system. The installation torque is ≤20N・m, and a single person can complete the entire disassembly and installation in 5 minutes. After installation, it fits seamlessly with the cab control panel and does not affect the use of other control components.

This control handle has passed multiple authoritative tests and certifications: GB/T 25684.8 Safety and performance requirements test for grader control components, 1 million cycles of oscillation fatigue test (no loosening, no increase in transmission clearance), 500 hours of salt spray + UV aging test (no rust on metal parts, no failure of seals), and wide temperature environment test from -40℃ to 80℃ (normal action response); the electronically controlled handle sensor has passed the ISO 7637 electromagnetic compatibility test, with no electromagnetic interference; the hydraulic valve of the hydraulic handle has passed the ISO 4401 hydraulic component reliability test, with a service life of ≥5000 hours.
