Daily maintenance of crane equipment
(3) check if all bolts are loose and short. Check the wear and tear of the wire rope, whether it has broken wire, check the lubrication condition of the wire rope. (5) check the fraying of the wire rope at the balance pulley and lubricate the pulley and the pulley shaft. (6) lubricate the gears. (7) check the condition of the pulley, see if it is flexible, have broken or cracked, and pay special attention to the wear and tear on the axle of the pulley. (8) check the fastening of the bolts of the motor, the gearbox, etc., and tighten up one by one. (9) check the lubrication condition of the gearbox, and its oil level shall be within the prescribed limits, and measures shall be taken to prevent the leakage of the oil seepage.
(5) check whether the fastening screw on the seal of the lifting mechanism is loose and short. (6) to check whether there are foreign objects in orbit that impede the movement of the bridge. (7) to check whether the transmission of the various agencies is normal or not.

(2) check the drum and wire rope winding on the pulley is normal, the presence of groove, channeling, knot, the phenomenon such as distortion, wire rope clamp bolt fastening, whether is there a double nut locking device. (3) check the safety protection switch and the limit switch to be accurate, flexible and reliable, especially if the rising limit is reliable. (4) check for good lubrication of all lubricants.
For maintenance and maintenance of bridge crane, as a result of the bridge crane parts is more, according to different technical characteristics of the parts, in the practical work of general maintenance and inspection cycle can be divided into weeks, months, years, the specific content of each cycle is as follows: Weekly inspection and maintenance (1) check the brake on the nut, split pin, positioning plate is excellent, loose, lever and spring no crack, the pin on the brake wheel bolt and buffer gasket is loose, and complete; Brake is reliable braking. Brake brake when they open the opening of the tile should be less than 1.0 mm and on the opposite side of the wheel braking distance gap should be equal, each shaft pin stuck not a phenomenon.
