• Equipment assembly

• Heavy component positioning

Typical hydraulic equipment:

• Hydraulic Jack

• Hydraulic Cylinder

• Hydraulic Pump

• Hydraulic  Hose

• Pressure Gauge

• Hydraulic Control System

Proper hydraulic selection and operation are essential for safe and accurate installation.

6. Girder Installation Process

A typical girder erection sequence includes:

Preparation Stage

• Review erection method statement

• Inspect equipment condition

• Confirm lifting arrangement

Lifting Stage

• Install lifting accessories

• Lift girder or segment

• Control movement and alignment

Positioning Stage

• Adjust girder position

• Check alignment

• Complete temporary fixing

Final Stage

• Complete connection works

• Remove temporary supports

• Perform inspection and acceptance

7. Bridge Construction Equipment Installation and Dismantling

Bridge construction equipment requires professional installation and dismantling procedures to ensure safety and efficiency.

Our knowledge covers:

Equipment Installation

Including:

• Launching Gantry assembly

• Hydraulic system connection
