description

Different from standard and KLS ordinary joysticks with conventional resistance and single structure, the PC LD upgraded joystick adopts customized low-resistance hydraulic channel design, which reduces internal pilot resistance by 28% compared with ordinary models, realizing super labor-saving operation. The internal valve core and valve sleeve are processed by ultra-precision grinding and pairing technology with tighter fit tolerance, effectively reducing internal leakage and pressure loss. Equipped with upgraded thickened high-toughness alloy double-strength return spring, the reset speed and reset completeness are comprehensively improved, completely eliminating residual displacement and floating failure. The high-strength cast aluminum valve body with integral reinforcement structure has stronger vibration resistance and structural stability. The upgraded multi-layer anti-rust, anti-corrosion and anti-fouling coating effectively isolates construction dust and muddy water erosion. Equipped with an enhanced thickened dust-proof rubber sleeve, it thoroughly prevents fine impurities from entering the valve cavity.

advantages

Exclusive LD Labor-saving Upgrade: Adopts custom low-resistance optimized oil circuit, which reduces internal pilot hydraulic resistance by 28% compared with ordinary KLS models. The operating hand feel is lighter and smoother, effectively solving the fatigue problem of heavy handle force during all-day high-frequency operation, greatly improving construction sustainability.
Double-strength Fast Full Reset System: Upgraded high-elasticity alloy reinforced spring group increases reset power and speed by 35%. It realizes instant and complete neutral return after releasing the handle, thoroughly eliminating common faults such as slow reset, residual offset and handle floating of conventional joysticks.
Ultra-precision Matching & Low Internal Leakage: The valve core and valve sleeve are ultra-fine ground and paired with micron-level tolerance, which minimizes internal pressure loss. The pilot pressure output is linear and proportional, making boom, arm, bucket and swing actions synchronous and sensitive without lag.
Enhanced Dust-proof & Anti-corrosion Performance: Equipped with thickened upgraded dust-proof rubber sleeve and multi-layer anti-fouling coating, it effectively blocks dust, sediment and fine impurities from invading the valve cavity. It maintains stable performance in harsh muddy and mountain working conditions, avoiding jitter and stuck failures caused by dirt accumulation.
Heavy-load Anti-fatigue & Long Service Life: Reinforced integral cast aluminum structure resists long-term cab vibration without deformation. The upgraded wear-resistant and aging-resistant accessories reduce daily maintenance frequency, with comprehensive stability and cost performance far exceeding conventional KLS versions.

FAQ

Q1: What is the difference between LD upgraded version and ordinary KLS joystick?
A: The ordinary KLS version is standard resistance with common reset speed, easy to cause hand fatigue and slight floating after long-term operation. The LD version is upgraded with low-resistance labor-saving oil circuit and double-strength reset spring, featuring lighter operation, faster full reset, lower internal leakage and stronger anti-fouling performance, specially for long-term heavy-load high-frequency harsh working conditions.
Q2: Does LD labor-saving design affect original machine control accuracy?
A: No. The LD version only optimizes internal flow resistance and reset structure, all pilot pressure parameters and stroke specifications follow OEM standards. The labor-saving design makes hydraulic feedback more linear, instead improving fine operation accuracy.
Q3: Does PC LD joystick have left and right handle distinction?
A: Yes. The LD upgraded joystick is divided into left-hand and right-hand versions with different oil port layouts. Please confirm the installation position before ordering to avoid mismatch.
Q4: Is debugging required after installing LD upgraded joystick?
A: No debugging is required. It fully matches PC-8 original hydraulic parameters and installation dimensions, plug-and-play, no change to original machine action logic and operating hand feel.
Q5: Can LD joystick be compatible with PC-7 series excavators?
A: No. The LD version is specially optimized for PC-8 series. The installation hole position and pilot port layout are different from PC-7, which cannot be directly universal.
