One of the highlights of Liebherr's exhibit at bauma 2007 was a new all-terrain crane. This newly developed 9-axle crane is not only the most powerful telehandler crane in the world, but also the longest telescopic crane with a length of 100 meters. The flagship crane's eight telescopic booms are 16 meters long each, surpassing the previous record that was first shown at the bauma trade fair in 1998.

The 100-meter-long telescopic boom consists of one base boom and seven telescopic booms. The arm length is automatically pinned and locked by the tried-and-tested telematik quick telescoping system. In addition, it is possible to form a 4-section short telescopic boom with a 4-section internal telescopic member, the principle of which is already being applied.

The radius of 55 meters can be reached by means of a 3-meter truss boom head.

A wide range of truss-type extension jibs are available for purchase. By using a luffing jib, it can be extended up to 126 meters and the lifting height can reach 170 meters. The Y-overlift system on the telescopic boom can be used in the position of the 4th or 8th section arm and significantly increases the lifting capacity.

XCMG is relatively good, mainly has the following advantages:

1.The boom is made of manganese steel, high-strength steel plate, and the boom has strong bearing capacity;

2.The turntable adopts an intelligent production line, 18 processes are completed in one go, and the intelligent rail guidance vehicle is automatically docked with the welding workstation, and the docking accuracy is in the degree;

3.The seals are imported parts, and the high-precision cold drawn tube solves the problem of oil leakage;

4.Hexagonal boom, good compromise performance and strong bending resistance;

5.There are after-sales service points in first- and second-tier cities across the country, and maintenance is more convenient.

The truck-mounted crane produced by Jiangsu Qizhuang is also very good, cost-effective, low, quality, used for two or three years, and the crane has not had any problems.

Are you talking about a straight arm crane or a knuckle arm crane?

The purpose of the crane is to lift, to meet the requirements can be, domestic XCMG, three.

The crane is inseparable from the wire rope, and the main varieties of domestic wire rope are as follows

1.Phosphate coated wire rope (Chinese patent), the steel wire is phosphated by manganese and zinc-manganese phosphate, the wear resistance and corrosion resistance of the steel wire are fully improved, and it is not easy to wear and rust so that the fatigue life of the phosphate coated wire rope is 3 times that of the smooth wire rope of the same structure (under comparable conditions in the laboratory), beyond the imported wire rope, the phosphate coated wire rope is fully replacing all kinds of smooth wire ropes, and can also replace the galvanized steel wire rope with a thin zinc layer (the corrosion resistance can be tested by salt spray test), and the service life is super long. The unit cost is lower, and the quality stability and reliability are better.

2.Galvanized steel wire rope, including hot-dip galvanizing and electro-galvanizing, the thicker the galvanized zinc layer, the stronger the corrosion resistance, and the thickness of the zinc layer is expressed in grams of square meters.

3.Stainless steel wire rope, mainly 304 or 316 stainless steel, has excellent anti-corrosion effect but is expensive.

4.Plastic-coated wire rope, based on carbon wire rope, the outer layer is coated with polyethylene, polypropylene or nylon.

5.Smooth wire rope, short service life, market demand has decreased sharply, and is being completely eliminated by phosphate coated wire rope.

For lifting machinery used in atmospheric environments, manganese-phosphated coated wire ropes are preferred, hot-dip galvanized-phosphating double-coated wire ropes are preferred in heavy corrosive environments, and offshore wire ropes are preferred in seawater. Please note that the name of the wire rope must be indicated in the purchase invoice, such as phosphate coated wire rope or 316 stainless steel wire rope, to prevent illegal enterprises from infringing on their legitimate rights and interests with counterfeit products, in addition, patented products are generally sprayed with a patent number on the outer packaging of the wire rope, and the warranty should have the main technical indicators, such as the type of phosphate film and the weight of the film (the size of the phosphate film film, wear resistance, corrosion resistance, etc. have an important impact on the service life of the wire rope), for reference only.
