In any job site machinery required lifting equipment and operating environment, considering the flexibility to do the mechanical stability and low ground pressure than the other elements of the requirements of professional lifting equipment, small to give you about the following areas points: 1, material handling, lifting and sporadic construction jobs require rapid approach of choosing a car cranes is appropriate, if the arm and leg retractable hydraulic truck crane is more favorable; for telescopic extension must be into a window or hole in the job lifting equipment installation, hydraulic truck crane is hoisting machinery of the best. Gantry crane spacing sizing, lifting equipment at work, should be left between the external dimensions and yard goods and transport vehicles passage certain spatial dimensions, in order to facilitate loading and unloading operations. When the general transport vehicle loading and unloading in the span, and doors should be kept above the legs have 0.7m spacing. Spreader should not work more than 0.5m spacing and transport vehicles, cargo lifting equipment when the legs get married, there should be more than 0.5m spacing. 3, the span and the boom length. Span is an important factor affecting the quality of their own. Selection, to meet the conditions of use and equipment Subject to span series of standards, should be minimized span. 4, to determine the principles tread, and can meet the requirements of the stability of the gantry crane along the track direction; attention span so tread B and S proportional relationship, and generally Wheelbase B = (1 / 4-1 / 6) S ; cargo dimensions to be able to pass the flat steel legs.
