Comparison

How It Compares With the Alternatives

6x2 crane lorry with 4.5 ton capacity	Lower lifting capacity and less stability on uneven ground but better fuel economy and easier to maneuver in tight urban spaces
Mobile crane with separate truck and crane	Higher cost and longer setup time but greater lifting height and reach for large construction projects
Standard flatbed truck with portable crane	More flexible in deployment but slower to set up and less stable during lifting operations

Operating Notes

Use Guide

Confirm left or right hand drive and local road regulations before placing the order
Inspect crane hydraulic fluid levels and filter condition before each shift
Use radio remote control or top seat operation only when the crane is fully supported and stable
Do not exceed 6.3 ton lifting capacity or extend boom beyond rated length
Engage anti-slewing impulse system before lifting and monitor over-wind alarm during operation
Perform daily checks on tires, brakes, and boom hinge points for wear or damage
Drain hydraulic system and store in dry conditions if the truck will not be used for over 30 days
