Boom Positioning & Load Alignmen

Rotate the crane to align the boom over the load. Adjust boom height and telescopic extension to position the hook correctly. Safety Tip: Follow the load chart and ensure lifting weight is within allowed limits for current boom radius and angle.

Crane Extension Preparation

Sit at operator seat and slowly operate boom angle handles to extend the main boom and telescopic sections. Move one handle at a time. Safety Tip: Never operate multiple boom handles simultaneously. Keep boom path clear of personnel.

Unlock outriggers and extend main and auxiliary outriggers fully. Place support pads under each outrigger on soft ground. Safety Tip: Ensure the truck is level. Incomplete extension may lead to tipping hazards.

Engaging Power Take-Off (PTO)

Ensure truck gear is in neutral and PTO switch is off. Start engine and wait for safe air pressure levels. Engage PTO slowly to drive the hydraulic crane system. Safety Tip: Confirm all control levers are neutral before operation. Improper PTO engagement can damage hydraulic components.

Pre-Operation Site Check

Park the truck on firm, level ground. Engage the parking brake. Inspect the surrounding area for obstacles, overhead lines, or unstable surfaces. Confirm the load is within crane rated capacity and lifting height limits. Safety Tip: Never operate on soft or sloped surfaces. Maintain at least 10 meters distance from high-voltage lines.
