Many customers did not carefully check the condition at the time of purchase crane, causing mention car soon after the emergence of many problems. Here, we tell you that you need to check the eight most part, to help you purchase a bed of roses.
Check hook marks and anti-off device meets the requirements, the 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 associated pin, jacket wear.
2. Wire Rope
Check the wire rope specifications, models and matching reel pulley meets the design requirements. Plate, Shengka, lease blocks, etc. rope rope fixed end fixtures to meet the requirements. Rope wear, broken wires, kinks, crushed, bent, broken stocks, corrosion, etc. are exceeded.
3. braking device
Set the brake, the brake of the type meets the design requirements, the brake lever, spring or without fatigue deformation, cracks and other defects; pins, spindles, brake wheel, brake pad wear if exceeded, hydraulic brake oil leaks ; brake gap adjustment, the braking capacity can meet the requirements.
Reel body, whether the tube edge fatigue cracks, breakage, etc.; rope grooves and cylinder wall wear is excessive; drum flange height with rope winding layers can match; guide rope, rope working conditions Meets Claim;
5. the pulley
Whether there is anti-off rope pulley groove means; pulley rope grooves, flange for cracks, broken edges, excessive wear and other conditions, pulley rotation is flexible.
Have severe slowdown runtime metal friction sound, vibration, radiation and other unusual sound shell; whether the shaft seal is intact, the fixing bolt is loose have defects and other conditions; gear lubricant selection, the oil level, the vertical gear lubrication pump running, open gear lubrication compliance.
Tread wheel, axle whether fatigue cracks phenomenon, wheel axle tread wear is excessive. Whether skew phenomenon running. What causes skew is.
Coupling parts for defects, loose connections, run impact of the phenomenon. Couplings, pin, axle pin hole, buffer rubber ring wear is excessive. Coupling and the two parts are connected are concentric.
