This heavy-duty telescopic boom truck crane for sale is an indispensable workhorse across high-demand sectors, with core use cases including:
Port Logistics & Freight Handling: Purpose-built for container handling, bulk cargo loading/unloading, and heavy material management in ports, docks, and freight yards, delivering efficient precise lifting for high-volume logistics operations.
Large-Scale Construction & Engineering: Ideal for lifting steel frames, concrete panels, and prefabricated structures on medium-to-large construction sites, reducing project timelines and improving on-site safety for contractors.
Industrial Manufacturing & Heavy Equipment Assembly: Perfect for positioning heavy industrial machinery, assembling large-scale production equipment, and supporting factory installation projects, with stable performance for continuous industrial lifting.
Heavy Municipal Infrastructure Maintenance: Efficiently handles large utility pole installation, heavy traffic signal setup, and complex urban infrastructure projects, with the power and flexibility to tackle demanding municipal tasks.
Park the truck on firm level ground, engage the parking brake, and fully extend all outriggers with appropriate support pads, especially on soft or uneven terrain. Inspect the work zone for overhead power lines and obstacles, and cross-verify the load weight against the lifting chart for the current boom radius and angle.
Operate only one control handle at a time, with slow steady movements to avoid load swinging or sudden pressure spikes. Never extend the working radius while rotating a loaded boom, and maintain a 10-meter minimum safety distance from high-voltage lines at all times. Never exceed rated capacity or leave a suspended heavy load unattended.
Perform full hydraulic maintenance every 500 operating hours or 6 months, including oil and filter replacement, hose inspection, and valve calibration. Lubricate all pivot points, boom slides, and hydraulic pins after each shift, with daily checks of hydraulic oil levels and bolt tightness. All maintenance must be performed by certified trained personnel.
It is designed for medium-to-heavy duty trucks with a minimum 900 mm mounting space and sufficient chassis load capacity to safely support 6.3 ton lifting operations and the crane’s own weight.
