The gears are designed for long service life and the drive shaft and drive gear are rated for endurance. Even though these gears are designed for long service life, an external visual inspection is not adequate, since their life can be significantly affected by bad maintenance (insufficient oil), defective seals, improper operation or overuse.

    0066340-200-07Y.C 7.7 Inspection and maintenance of wire rope Being a crucial component for crane lifting, the wire rope will directly affect the assembling work and safety on the construction site. Therefore, much emphasis should be put on the use, maintenance and regular inspection of wire rope. 7.7.1 Handling and transport of wire rope The wire rope should be handled and transported with utmost care.

  • Page 411 0066340-200-07Y.C It is recommended that the old rope should be removed prior to fitting a new rope. If the old rope is used as a lead rope to pull the new one through the reeving system, do not connect them together by directly welding or binding their rope ends; instead, they should be connected with a Chinese finger.

In many cases, the rope should be unwound or wound properly with the help of an external force. Enough tensioning load can be generated on the reel by depressing the wooden board underneath one flanges of the reel or holding the braking bar that is connected with the reel axles (see the figure above).

    0066340-200-07Y.C undergoing “trial-running”, all components of the rope can be adjusted to real operating condition. The crane should be used for lifting at approximately 10% of the normal load in order to stabilize the rope. During the trial-running, crossing, kinking, twisting, and excessive bending as well as scratch of wire rope should be avoided.
  • Page 414 0066340-200-07Y.C Caution: if this is not observed, the rope can be damaged! g) Measures to eliminate torsion compensation 1) Set down the load hook Lower the load hook as much as possible, so that the greatest rope length between pulley block and load hook is exposed to compensation (twist, point 4). 2) Determine the rope lay direction\turning direction of rope First determine in which direction the load hook is twisted.
  • Page 415 0066340-200-07Y.C Since a non-stretch rope construction is relatively safe from torsion and it can only be stretched a little (actually, the torsion will not make the rope deviate from the groove of rope pulley), the hoisting movements without a load must be repeated several times. after getting the compensating turn to the end of the rope, reattach the rope end again to the fixed point and repeat the hoisting movements without a load one or several times so that the torsion compensation can be distributed over the complete length of...
