1. Bailey Bridge Bailey Bridge is a standard bridge equipment, adopted extensively and the most popular inthe world, possessing the features of simple structure, convenient transport, speedy erection and easy disassembling, while having the advantage of heavy loading capacity, great stability and long fatigue life being capable of an alternative span, loading capacity and mixture form to erect all kinds and usage of Temporary Bridges, Emergency Bridges and Fixed Bridges. Using the compact panel bridge equipment, the suspension bridges of varied span can be erected. The bridge has the advantages of few components, light weight and low cost. 2. Light Truss Bridge Light Truss Bridge is a kind of assembly bridge down supporting. It possesses the advantages of simple structure, light weight, erecting rapidly, heavy loading capacity, great stability and low cost. Accordance with load standard of AASHTO, the bridge is designed by HS20-44 truck load with double roadways or four roadways, crowd load 3000 Pa, wind speed 90mph .with roadway width 7.5m-15m inner and sidewalk 1.8m outside. Reinforced concrete deck or steel deck can be adopted 3. Suspension Bridge Suspension Bridge is a kind of suspended-cable-system bridge, in which 321 Highway compact panels and the steel decks are used as members. The suspension bridge is made by our Company, erected over MK River, Myanmar, being 174 meters long, all members are hoisted with the erection device made of reinforced panels. The erection effect is up to 20-24m/day, even 30m per day. The erection device of bridge tower is also up to requirement. 4. Steel Truss bridge Steel Truss Bridge is a kind of bridge down supporting and deltoid welded , and possessing the advantages of simple structure , erecting rapidly , heavy loading capacity and great stability . The bridge has free selection in span and roadway grade according to various demands. The bridge is designed by HS20-44 truck load with double roadway or four roadway , crowd load 3000 Pa, wind speed 90mph. It can be designed as different spans like from3 to 11 hole with roadway width 8.5m-15m , reinforced concrete railing , sidewalk 1.8m . 5. ribbon pontoon bridge Ribbon pontoon bridge is a standard heavy pontoon equipment used for constructing 60tf and 20tf floating bridges and 40tf, 60tf and 110tf ferry rafts over a current velocity not higher than 2.5m/s. Loading capacity for tracked load is 60T, and for wheeled load on axle 13T. The complete set consists of 14 interior bays, 2 ramps, 5 motorboats and 16 transporters of pontoon, 5 transporters of boat. The pontoon body is the tight-box integrating box for construction of floating bridge or ferry raft; each interior bay (or ramp bay) is a section of a floating bridge or a ferry raft with the same structure; wide roadway is used as either a single-lane for heavy loads or a double-lane for light loads; no wharf construction is required in raft crossing, its accompanied ramps facilitating loading and unloading after mooring. 6. floating bridge Multipurpose Pontoon,a floating structural units, has extensive adaptability. New type pontoon-to-pontoon connectors are adopted and their plane dimensions modularized, the pontoons can be connected up easily and quickly in lengthwise, transverse, T-shape and angular connecting configurations. The flat decking of the pontoon is strong enough to bear the loads of heavy-duty equipment and vehicle directly. The pontoon bottom may be stranded to bear the loads. Multipurpose Pontoon can be used for erection of highway floating bridges, ferrying barges, floating quays, jetty; for, in railway construction, erection of temporary floating bridges, floating piers, ferry raft; for assembly of floating crane, drilling and piling platforms on water; and for construction of a helicopter landing platform, in wartime, for logistic supply between warship and islands.
