What is the difference between bridge and gantry crane
The general idea of installation: 1, laying gantry crane rail (generally the laying), but in the installation must be carried out before the crane on the track before detection, the gauge error is not more than 10 mm; 2, the installation of the cart on both sides of the parallelism, the verticality that can pull round pull line, diagonal, full justice etc. means of correction, (if the cart is not adjusted, rail gnawing will make you a headache to difficult adjustment) 3, lifting the legs together, and the connection, and the cable wind rope, a leg 4 rope hook (after loose ropes fixed rear legs will not pour down)
Our general door crane gantry machine life, also call. It is composed of four parts: the control part of the big leg of the main beam. Design and installation of national standards, recommended standard design, calculation of strength, stiffness, stability, etc.. The installation site for each crane, environment, and different restrictions on various conditions, the theory has a set of installation scheme, but small span, small weight of gantry crane installation, specializing in the installation of the worker's experience is very rich, they know how to install, so don't give a written installation scheme
Mosaic good (girder girder hoisting a piece also has two tablets, user requirements set) on both sides at the same time on the leg lifting, erect, then workers quickly climbed up, tighten the screws, then the trolley to the main girder structure, just part of the installation on all OK.The main movement in the road: beam yard hanging template, hanging beam, frame beamRailway: beam yard hanging template, hanging beam, frame beamShipyard: hanging welded plateAlso used for cargo handling occasionsWrite bad, please forgive me
