Genuine XCMG 803754106 Universal Circular Spirit Level (Cross Bullseye Level)

Overview

The 803754106 is a factory-calibrated universal circular spirit level built to original XCMG equipment specifications. It acts as a critical safety and alignment component for XCMG mobile cranes, delivering real-time horizontal posture feedback to support stable, compliant lifting operations.

Engineered to withstand the vibration, dust and temperature swings of construction job sites, this OEM level matches the exact fit, calibration and durability standards of the factory-installed part, requiring no modification during replacement.

Key Design & Construction Features

• 360° Omnidirectional Detection: Full bullseye layout with concentric ring markings and crosshair scales detects tilt across all horizontal axes, allowing operators to read deviation direction and magnitude at a glance.

• Factory-Graduated Precision: Calibrated to a ±4° measuring range with 1° increment divisions, delivering the consistent accuracy required to keep cranes within rated load chart limits.

• Rugged Aluminum Housing: Machined aluminum alloy body with an integrated mounting flange and bolted fixing points resists impact, continuous vibration and corrosion on outdoor job sites.

• Low-Light Readable Dial: Luminous scale markings remain visible in dawn, dusk and nighttime working conditions, supporting multi-shift and around-the-clock construction schedules.

• Sealed Long-Life Vial: Hermetically sealed spirit vial prevents liquid evaporation and contamination, maintaining stable bubble performance and reliable readings over extended service intervals.

Technical Specifications

Application & Operating Function

This spirit level is mounted on the slewing platform or outrigger control panel of XCMG truck cranes. During pre-lift setup, operators reference the bubble position to adjust the extension of each individual outrigger leg, bringing the full crane chassis to a true horizontal plane.

Accurate chassis leveling is a foundational safety step for mobile crane work:

• Eliminates side tipping risks caused by off-level posture and uneven load distribution

• Ensures the crane operates within its official rated lifting capacity and load chart parameters

• Reduces uneven wear on slewing bearings, hydraulic cylinders and structural steel components

• Supports stable lifting performance across building sites, port yards, mining operations and road construction projects

Compatibility

Original XCMG part number 803754106 is engineered as a direct drop-in replacement for QY25K and QY25T series truck cranes. It retains identical mounting dimensions, calibration standards and performance characteristics as the factory-fitted component.
