HOOK WEDGE FOR 16MM WIRE ROOP XCMG CRANE
This assembly is a critical component for the load hoist system on XCMG truck cranes. It provides a secure and reliable method for terminating the wire rope at the hook block or boom tip.
High-Strength Material: Manufactured from high-strength alloy steel to withstand the high loads and fatigue associated with crane operations. The socket and wedge are often heat-treated for enhanced durability and wear resistance .
Precision Fit: The wedge and socket are precisely machined to ensure a snug, secure fit for the specified 16mm wire rope, preventing slippage and rope damage .
"Go/No-Go" Feature: The wedge incorporates a gauge feature to verify correct rope sizing: the 16mm rope must pass through the "go" hole but not the "no-go" hole .
Anti-Corrosion Treatment: Components are typically surface-treated (e.g., painted or zinc-plated) to resist corrosion and extend service life in harsh environments.
1. Preparation
Before installation, seize the wire rope approximately 0.9 - 1.2 meters from the end using wire or hose clamps, with a gap between them .
The dead end of the rope should be fused to prevent core slippage .
2. Installation
Insert the 16mm wire rope through the wedge socket.
Place the wedge into the socket and push it firmly to lock the rope in place. The dead end of the rope must rest on the sloped portion of the socket .
Use a hammer to initially seat the wedge. A first lift (of significant weight) will fully seat it .
3. Securing
Secure the dead end of the rope by installing a wire rope clip or the designated retaining pin/bolt through the wedge .
Tighten the clip nuts to the recommended torque specification for a 16mm rope .
4. Safety Checks
Ensure the flat face of the socket is facing out when attaching to the boom head to avoid structural damage .
