Bridge girder launcher maximum capacity is 900 ton. Bridge girder launcher for tunnel is designed to launch through tunnel with minimum dismantling operation. This equipment with below advantages: light weight, good stability, precise self positioning, precise beam positioning and easy operating. The equipment also comes with centralize control system, multi speed crane, hydraulic powered support, mechanical powered self advancing system and spare-parts.
PROFIBUS is used for real-time distributed control. Safety feature including a complete censoring system with self positioning and correcting functionality, crane with triple breaking system, emergency stop button and limit switch. Nridge girder launcher for tunnel Series Full Span Bridge Erector is designed to be fit into and deliver by 40 footer open top container. All HCR products are fully trial assembled and tested in the factory before delivery.
Gantry Crane For Product/Lift Concrete Bridge Girder
Capacity: 5t ~ 900t
Span length: 12m ~ 35m
Lifting height: 6m ~ 28m
Structure type: box type or truss type
Gantry crane with trolley are widely used in concrete girder fabricating yard for product or lift concrete bridge girder.It consists of four main parts, bridge structure, traveling mechanism, trolley and electric equipment.
The bridge is welded structure of box-type or truss-type girder. All movements of the crane are controlled from the cabin. Either rigid shapes of steel (angles or tees) or flexible insulated cable shall be selected to be utilized as runway conductors.
Girder Carrier
Capacity: 160~900t
Traveling speed:0.03~60km/h
Driving direction:bidirectional
Girder carrier is suitable for transporting and installing whole concrete girder in high speed railway construction. Girder transporter can carry concrete box girder from precast yard to the worksite by way of pavement, railway roadbed, bridge
and culvert, cooperating with the bridge girder launcher to finish installing girders. The girder transporter can carry the bridge girder launcher to another worksite in short distance, and also carry it to pass the passenger special double line tunnel.
Main Features of 450T Bridge Launcher
Construct bridge connected with tunnel, reduce cost of dismounting many times 1. four fixed points lifting precast girders with balanced lifting capacity ensure the safety of concrete box girder and lifting system structure. Slight longitudinal and lateral movement of lifting system can realize accurate positioning as installing box girder 2. launching nose and bridge girder launcher do a cooperative work to cross piers longitudinally, featuring easy operation, safe and reliable 3.can realize span shift installation and curved bridge erection, tyred girder transporter can directly carry the bridge girder launcher to transfer sites and pass the tunnels 4.matched with the launching nose, lifting trolley and auxiliary overhead crane, the bridge girder launcher can install the first and last girders as well as girders for tunnel entrance and exit.

Operate Requirements of 450T Bridge Launcher
1.Adjusting the height of transverse rails of front legs and middle legs when erecting girder or moving from one pier to keep main girder’s longitudinal slope≤0.5%,transverse slope≤0.5%. 2.The normal working wind speed should less than 6 grade when bridge girder launcher works in the open air ; when the wind exceed 6 grade, the bridge girder launcher shouldn’t moving from one pier to next pier, and components should be locked; the machine can’t work in thunderstorm day and must cut off power. 3.check the steel rope is broken or not, the circuitry leaks electricity or not, the brake is reliable or not, and after the reducers get enough lubricating oil and the oil lubricate the open gears, the machine start to work; the safe circle of steel rope on the drum shouldn’t less than 3;checking the surface and fixed parts after every shift of steel rope and making a specific check every 7~11 days; 4. the brake system of winch is allowed to start again after it checked; 5. the lifting ,longitudinal traveling and transverse traveling shouldn’t work together; the speed of lifting and translational velocity should be slowly to avoid leaning and side tumbling.
