Line hanging job jog performance checks mainly for line hanging job during hoisting, slewing, luffing mechanism of action sensitivity and accuracy for debugging. Line hanging debugging requirements: when the relevant agencies to ensure that the lifting operation smooth, accurate operation, no creep, vibration, shock and driving power increases and other abnormal phenomena: lifting, jogging good performance slewing, and luffing mechanism. Debugging conditions: basic boom, boom elevation of 50 ° 20 tons of traffic, lifting the rate of work under the rated lifting capacity to stop after one meter height. Debugging methods: pulling the joystick to the crane (down) position 10 tons of traffic, a slight movement when heavy braking immediately. Continuous landing boom 10 times, measuring the weight cumulative distance horizontal movement, and calculate the average per-action arm landing shift amount. Its value should meet the specified value, or should be adjusted brake reliability and sensitivity (wire luffing mechanism) or the back pressure in the hydraulic circuit balancing valves and secondary safety valve set pressure (hydraulic cylinder luffing). Eight components of general line hanging daily (1) line hanging hook hook check mark and meets the requirements of the anti-separation device, hook for cracks, delamination and other defects; hook wear section, increase the amount of the opening degree of torsional deformation , is excessive; hook neck and face or without fatigue deformation, cracks and relevant pin, sleeve wear. (2) line hanging rope rope inspection specifications, models and matching pulley reel meets the design requirements. Plate, Shengka, lease and other pieces rope rope fixed end fixtures to meet the requirements. Rope wear, broken wires, kinks, crushed, bent, broken stocks, corrosion, etc. are exceeded. (3) line hanging brakes brake settings, brake type meets the design requirements, the brake lever, spring or without fatigue deformation, cracks and other defects; pins, spindles, brake wheel, brake lining wear excessive, hydraulic brake oil leaks; brake clearance adjustment, the braking capacity can meet the requirements. (4) line hanging of roll body tube edge or without fatigue cracks, damage, etc.; rope grooves and cylinder wall wear is excessive; drum rim height and rope winding layers can match; guide rope, spooling device work meets the requirements; (5) whether the row hanging pulley pulley rope off with anti-tank device; rope pulley groove rim for cracks, edge damage, excessive wear and other conditions, pulley rotation is flexible. (6) line hanging gear reducer runtime whether the violent sound of metal friction, vibration, radiation, and other unusual sounds housing; whether the shaft seal is intact, there is defect fixing bolts are loose and other conditions; gear lubricant selection, oil height, vertical reducer oil pump is running, open gear lubrication, and other compliance requirements. (7) line hanging wheel wheel tread, axle whether fatigue cracks phenomenon, wheel axle wear is excessive. Whether skew phenomenon running. What causes skew is. 15 tons lane carriageway _ _ Puning heavy generous generous by heavy machinery Co., Ltd., Henan Province.
