141900480 Main Boom Head Connection Box for XCMG XCA Series Truck Cranes

Product Overview

This main boom head connection box is an OEM-spec electrical component purpose-built for XCMG XCA series truck cranes. Installed at the tip of the main boom, it acts as the central hub that organizes power supply and signal transmission for all boom-head electrical devices, including working lights, length-angle sensors and limit switches.

Key Features & Build

• Heavy-Duty Enclosure: The housing is constructed from high-strength die-cast aluminum with a fully sealed structure, providing solid dust and water resistance for sustained operation in outdoor construction sites, high-altitude lifting jobs and variable weather conditions.

• Rugged Connector Design: Fitted with standard circular aviation connectors with protective dust caps, it maintains secure electrical contact even with frequent boom movements. The pre-assembled wiring harness with factory-matched connector supports direct plug-and-play replacement.

• Integrated On-Site Control: Built-in control circuitry enables local control of boom head lighting and signal switching, with clearly engraved function icons for easy on-site operation and troubleshooting.

• Stable Signal Transmission: Internal wiring adopts a shielded layout to minimize electromagnetic interference, ensuring accurate data delivery from boom sensors to the crane’s on-board control system.

Role in Crane Electrical System

As a key part of the boom electrical architecture, this connection box consolidates scattered wiring at the boom head into a single, manageable unit, reducing potential failure points and improving overall system reliability. It is widely used on XCMG XCA series all-terrain cranes deployed in construction, port handling, logistics and heavy lifting scenarios.

Compatibility Information

This unit is manufactured to original XCMG dimensions and electrical specifications, serving as a direct replacement for the factory-fitted connection box on XCA series cranes. For QY series and other XCMG crane models, please verify the part number against your equipment’s parts catalog.

Maintenance Guidance

During routine service, inspect the seal condition of connector caps and tighten housing screws periodically. Clean connector contact pins to prevent poor conductivity caused by dust buildup or oxidation.
