Double-girder bridge crane YZ

for workshops

Widely used in: Machinery manufacturing, smelting workshop, thermal processing workshop, etc. YZ Type 75／20~125／32t Double-beam Cast Bridge Crane Double welding box girder, beam deflection with DIN/FEM standard Steel Material: Chinese standard Q235B and Q345B Trolley rail is made of high strength hot rolled flat steel (16 Mn) Epoxy zinc-rich painting for one bottoms and two sides of 120μm thick, to achieve a long lifespan, beautiful appearance and good luster The girder and end beam are connected together by high strength bolts to ensure the structure strength and precision of the whole machine The end beams are equipped with flat wheel or double rim wheels, anti-friction bearings, buffer blocks and derailment preventing end plate Maintenance walkway is located on one side of the main girder, consisting of flower pattern plate, 1050meters handrail. 1. Both side of all the steel plate of crane are pretreatment by pretreatment production line,Sand blasting-- Primer spray--Primer drying. Eliminate the innerstress of steel plate, increase the adhesive force of the steel structure. Ensure the appearance and anticorrosion quality. 2. Steel plate cutting adapt whole sets Messer CNC plasma cutting machine from Germany, vrey fast cutting speed, little deformation, High precision, Deviation could be controled within 1mm, it insure the raw material at high quality standard and can reach top level in the industry.
