Electric double girder gantry crane installation

Installation is divided into several parts, as follows:
1 Before Installation and Precautions
(A) information on a variety of technical drawings and be very familiar if caused by improper transportation or storage errors or defects should be promptly corrected or eliminated, corrected or eliminated before installation.
(1) Before installation, you should check the rotating parts are flexible, all joints are secure, the bearing is short of oil and so on.
(1) Cranes in the handling or moving, should avoid a collision, lifting pitched when the main beam is strictly prohibited beam directly on the ground or drag; store when stable, flat pad is symmetrical and can not be tilted on the ground, not with water, otherwise it would   hoist gantry crane   stripping rust.
(2) the installation of machinery and equipment
Crane erection, according to the size of the device can be divided and part of the overall erection erection. During erection, you should check the track installation quality, and make a record.
3 installation of electrical equipment
(1) on-site installation of electrical equipment are: resistors, switches, control panel, spot lights, junction boxes, trays as well as threading pipe welded parts, resistors, and control panel installation location, make the appropriate depending on the circumstances permitted adjusted.
(2) All wire end and beginning of the number should be consistent with the schematic diagram, overhead gantry crane  to facilitate future installation and maintenance. If 6mm2 wires in the following section, you can not wire connectors, but it should hold the tin. Conductors such as laying in the tube, you can not have joints.
(3) can not have a slide-wire contact surface rust, if any, should be removed. Slip line angle horizontal and vertical centerline, the error shall not exceed ± 20mm.
(4) power and steering circuit side, measuring the insulation resistance, the need to turn all aspects of electrical equipment, bridge gantry crane  the measured value should be less than 0.8 megohms, phase insulation resistance value should not differ too much resistance wet areas will decline, the minimum can be reduced to 0.4 megohms.
