MG45 double girder gantry crane technical maintenance routine maintenance procedures 1. Clean the outside of the body; 2, check control system; 3, check the machine's limit device; 4, check the switch, starter, alternator and battery; 5, check lighting, instruments, lights; 6, after the work of clearing the cab, escalators, main beam ministries of dirt, dust; 7, control systems and control cabinet cab electrical components should be sensitive and reliable mg type hook gantry Crane, malfunction or damage if timely replacement; 8, make sure the machine stopper flexible mg double girder gantry crane hook, especially commutation limit, self-locking limit, door handle girder spacing, Rope height limit other major stop, failure to ensure the timely replacement of all bolts, nuts and effective reasonable adjustment key switch, working conditions starter, generator mg double girder gantry crane, to ensure the normal work; supplementary Check the battery level lighting, instrument systems and all lights work, and as the case may be maintenance, handling regular maintenance (every 300 hours of work) to complete all routine maintenance. Fixed rope to check the situation at the end of the rope; rope must be in the correct way lubrication, lubrication application before kerosene soaked rags used to clean oil; wire rope should be replaced the following conditions: a surge in the number of broken wires in more than 10%; diameter reduction 7% smaller than the nominal diameter; rope kink occurs; significantly loosened, severe corrosion, replacement of the rope must meet the original design number, size and other requirements tensile steel wire raceway surface of the bearing inner and outer rings of the ball wears stripes, spalling pits, cracks or excessive bearing radial clearance should be replaced with new bearings. How common gantry crane maintenance. The company has independent intellectual and industrial property rights, earlier passed the ISO9001 international quality management system, ISO14001 environmental management system environment, GB / T28001 Occupational Health and Safety Management System and the International Union for certification, the establishment of a sound quality assurance system and TQC total quality management system, the company has the right to operate independent import and export qualification and further explore the international market, to build a world brand. Our company is specialized in the production of generic generic generic gantry crane manufacturers. So, how common gantry crane routine maintenance it? The security settings rack drive luffing drive 1. Crane should be sensitive and reliable. Because there is a rack in the job easier impact wear, resulting in starting and braking, such as security settings unreliable and dangerous boom over travel and fall occur. Hydraulic luffing drive 2. Crane is a compact, two-way force can withstand characteristics, but its piston, cylinder, pushrod has a certain precision, to strengthen maintenance. 3. Install the bolts to use a torque wrench, which allows more uniform preload. Because gantry crane operation prone to vibration, to regularly check for loose bolts. 4. The use of hydraulically driven hydraulic brake should always check the quantity of oil, add the right amount of time to be inadequate. To check whether the pipe joints with hydraulic oil leakage or air into the cylinder inside, if there is air in the fuel tank should be immediately removed. 5. Run the institutions and brakes should be inspected regularly, especially if you want to check the crane brake solenoid is stuck due to vibration does not move, but also check the solenoid coil is wet. 6. species within the hydraulic oil pump, the temperature should be selected depending on the region. To prevent the pump suction air in the work process, should always check the discharge. mg double girder gantry crane, Shanxi mg type, Henan Province, Henan gravity provided by the Crane Co. gravity.
