Specifications

General description
The Double Girder Overhead Crane with Electric Hoist is traveling on fixed support.
The frame adopts box type welding mechanism, and it used together with CD1/MD1 or HC/HM model electric hoist as a complete set, It is an mid-duty class crane, the capacity is from 3 tons to 20 tons. The span is 10.5-31.5m.The lifting height is 6~18 meters.
Working grade is A3~A4. Working temperature is -20°C to 40°C
Double Girder Overhead Crane with Electric Hoist is composed of box type bridge frame, lifting trolley, crane traveling mechanism and electrical system. It employs fixed electric hoist, which is fitted on trolley frame as the hoisting mechanism. The structure, simple and convenient, features low entire height and light dead weight, so that it is applicable to operational sites of medium and small lifting load such as factories and mines, workshops and warehouses.
Mechanical parts
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.
