Product Description

Product Description

Bridge construction is very complicated, the reliability of equipment directly affects the success or failure of the project. RONGMEI's 70MPa hydraulic system supports the bridge components. Lift and other applications provide reliable protection.

In a bridge erection project, an electric pump station can power from 4 to 32 (or more) synchronous jacking jacks to install or replace bridge support pads.

Due to the increasingly busy traffic, the strengthening work of highway Bridges and overpasses has been put on the agenda. Traffic flow can be increased by adding additional piers and distributing the load equally between the old and new piers.

 

Working Principle

1. Stowage calculation and stowage vehicle layout

In order to ensure the overall force and synchronous lifting of the one-hole bridge, the weight of the upper structure such as the bridge floor, middle beam, side beam and guardrail should first be calculated according to the design document, and then the load is loaded according to the principle of overall weight balance, usually the vehicle is evenly arranged and loaded to ensure the balance of the force during the lifting process.

2. Main construction materials and equipment

Mechanical name: generator set, welding machine, hydraulic station, unidirectional ultra-thin jack, dial indicator, manual jack, loading vehicle, lifting basket frame, gas cutting equipment, hydraulic distribution equalizer, high pressure distribution oil pipe.
