The invention relates to a self-adjusting preload steel wire rope rigging. The self-adjusting preload steel wire rope rigging comprises a rigging body, wherein the middle part of the rigging body is provided with a plurality of outer coniform trapezoidal bulges, an upper semicircular body and a lower semicircular body which are buckled together are arranged at the outside of the outer coniform trapezoidal bulges; one end of each of the upper semicircular body and the lower semicircular body is provided with a fixing plate, and each of the other ends of the upper semicircular body and the lower semicircular body is provided with an external spring support; the rigging body penetrates through the fixing plate and the external spring support and then is fixed by a locking nut; the middle parts of the inner sides of the upper semicircular body and the lower semicircular body are provided with projected blocks; a cavity is formed between the projected blocks and the spring support; the rigging body is sleeved with a spiral spring; the upper semicircular body and the lower semicircular body are compressed on the fixing plate under the function of the preload of the spiral spring. The self-adjusting preload steel wire rope rigging provided by the invention automatically adjusts through the spiral spring, which is timely and reliable; and the cumbersome labor is saved, and the performance reduction due as a telescopic boom is not in place due to the untimely adjusting as well as the not smooth operation and the early damage of the parts due to the impact can be avoided; electrostatic spray is performed on the surfaces of the outer coniform trapezoidal bulges and the inner coniform trapezoidal bulges, so that the friction resistance of the automatic adjustment can be reduced.

The invention discloses a rigid wear-resistant material with high strength. The rigid wear-resistant material with high strength comprises components by mass as follows: 1.9% or higher-2.8% or lower of C, 1.4% or higher-2.9% or lower of Si, 0.6% or higher-0.8% or lower of Mn, 5% or higher-12% or lower of Cr, 0.6% or higher-1.2% or lower of Cu, 0.1% or higher-0.3% or lower of Mo, 0.01% or higher-0.04% or lower of P, 0.01% or higher-0.04% or lower of S and the balance of Fe and inevitable impurities. The wear-resistant material is high in strength and rigidity and good in wear resistance.
