Detailed Description: Segmental overhead and underslung launching gantry is whole span box girder segment erection construction equipment, simple structure, convenient usage, can greatly improve the construction efficiency. 1. of the main girder of bridge erecting machine with super imposed box girder structure, high stiffness, small deflection. 2. the main structure uses the symmetrical design principle. 3. the segmental overhead and underslung launching gantry can carry out two-way construction, and can adapt to the bridge beam feeding and tail beam feeding in two conditions, strong adaptability. 4. this segmental overhead and underslung launching gantry operation has the advantages of simple structure, convenient use. Parameter Details: Feature:Gantry Crane Condition:New Rated Loading Capacity:1600t Rated Lifting Moment:16000kn Max. Lifting Load:1600t Max. Lifting Height:560m Span:50m Package: 1. Electric parts of segmental overhead and underslung launching gantry are packed by high quality plywood crate, to reduce distortion in conveying; 2. Main beams, end beams and electric winch are packed by plastic woven cloth. It can reduce abrasion when transport. Delivery: 1. If the size of whole crane are suitable for container ship, usually by container; 2. If the size is too big, usually by bulk ship or by container after truncation; 3. Transport ways are based on reducing cost for you and keep the crane performance!
