description

PC grapple joystick adopts high‑strength cast‑aluminum integral valve body, manufactured strictly according to PC‑8 series installation dimension and auxiliary pilot hydraulic parameters. The internal auxiliary oil passages are precisely polished to reduce hydraulic resistance for grapple opening‑closing and rotation actions. Equipped with high‑toughness reinforced return spring set and high‑wear‑resistance sealing group, it maintains stable reset performance and sealing property after millions‑time frequent auxiliary‑action operation. Reasonable oil‑port layout matches PC‑8 auxiliary pipeline modification requirements, convenient for on‑site grapple‑attachment refitting. The valve‑body surface adopts multi‑layer anti‑rust and anti‑corrosion coating, equipped with heavy‑duty dust‑proof rubber sleeve to block dust and debris entering inner valve chamber. Each finished grapple joystick passes auxiliary pilot pressure test, full‑stroke detection and neutral‑reset calibration. It features stable pressure output, low internal leakage and long service life, which is high‑quality special replacement part for PC‑8 excavator grapple modification.

advantages

Grapple‑specialized Oil‑path Design: Optimized auxiliary pilot oil‑channel specially for grapple opening‑closing and rotary actions. Output proportional stable pressure, make clamping‑releasing and rotating response smooth without lag, avoid common slow‑action defects of general modified joysticks.
Reinforced Reset Performance for Frequent Operation: Adopts upgraded high‑toughness return spring group, adapts to high‑frequency continuous grab‑rotate operation. Handle can rapidly and completely return‑to‑neutral after releasing, no offset residual position, improve operation accuracy for material‑handling work.
Low‑leakage Precision Spool‑sleeve Matching: Fine‑ground valve‑core and valve‑sleeve pair reduces internal leakage and pressure loss. Auxiliary pilot pressure keeps stable under long‑time intermittent operation, preventing grapple weak clamping force caused by internal leakage.
Anti‑vibration & Dust‑proof Reliable Structure: High‑rigidity cast‑aluminum valve body resists cab vibration; heavy‑duty dust‑proof rubber sleeve prevents debris entering valve cavity. Effectively reduce stuck and jitter risks under harsh material‑site working environment.
Convenient for On‑site Refitting: Installation hole position and oil‑port layout follow PC‑8 cab installation standard. It can be directly applied for grapple‑attachment refitting, no large‑scale modification to original machine structure, shorten refitting cycle.

FAQ

Q1: What failures will occur when using ordinary joysticks for grapple refitting?
A: Ordinary general‑purpose joysticks are not designed for frequent auxiliary‑action working conditions. After long‑time grab‑rotate operation, they are prone to spring fatigue, spool wear and internal leakage. Typical symptoms include insensitive grapple action, insufficient clamping force, slow reset and handle drifting.
Q2: Does PC grapple joystick control both grapple open‑close and rotation?
A: Yes. This auxiliary grapple joystick realizes two‑way output, independently controls grapple clamping/releasing and 360‑degree rotary actions, meeting full‑function operation requirement for wood‑grabber attachments.
Q3: Is extra hydraulic debugging required after installing PC grapple joystick?
A: No extra debugging is needed. It matches PC‑8 auxiliary pilot hydraulic parameters. After pipeline connection for grapple attachment, it can work normally without adjusting main‑machine hydraulic system.
Q4: Can PC grapple joystick be installed on original main control handle position?
A: It shares the same cab mounting hole size with PC‑8 main joystick. It can be installed on original handle position for refitting, or be arranged as independent auxiliary handle according to customer modification scheme.
Q5: Can PC grapple joystick be used for PC‑7 series excavators?
A: It is specially developed for PC‑8 series. Installation hole and auxiliary oil‑port layout differ from PC‑7, cannot be directly interchanged for refitting.
