Detailed Description

NHL by cooperating with the US UNITRIG Corporation established a specialized company in manufacturing UNITRIG electric-wheel dum

In 2005, NHL by cooperating with the US UNITRIG Corporation established a specialized company in manufacturing UNITRIG electric-wheel dump trucks ranging from 120t to 360t, as an important part of NHL's development strategy. The cooperation will make NHL's products got extended from 23t to 360t. Such a relatively complete series of products can better satisfy users' demands and expand market share.

Unit Rig, a sole subsidiary of US Terex Group, was founded in 1935, headquartering in Tulsa in the USA, and specialized in producing petroleum drilling equipment, traction type equipment and army supplies for the World War II at that time. Unit Rig pioneered the development of the diesel electric drive, rear dump truck for use in open pit mining operations. The prototype truck rolled out formally on January 27, 1960 and the first production models entered service in the last half of 1963. The truck was an immediate success gaining market share steadily. Unit Rig's heavy-duty electrically driven mining rear dump trucks with payload capacities covering 120t, 150t, 170t-190t, 190t-205t, 240t-260t and 360t, and bottom dump coal hopper cars ranging from 180t to 260t, are mainly applied to mines of copper, coal, gold and iron, with the market covering 6 continents and the total sales exceeding 4,500 trucks, over 50% of the total world fleet. There are 44 sets of MT3600 (154t) are serving mines in China.

Such trucks are provided with the following technical characteristics and performance advantages:
Optional Engine:
Engines of Cummins and Detroit provided for choice, highly efficient and economic.
Firm Structure:
A firmly and strongly structured frame is an important element for a long-life haulage trucks. An electric-wheel mining truck is particularly characterized by the design of straight longitudinal beam, extinguishing stress concentrated source.
It, of a dual-box-section structure, adopts high strength and dilute alloy rolled steel, simplifying welding procedure and reducing embrittlement caused by hydrogen gas in the welding process.
The welding seam with submerged arc welding gets stress further reduced. Durability limit is increased by 36%, which means a 400% increase of the fatigue life of welding seams.
The design of deep section main longitudinal girder at the key part of the frame makes the stress reduced by 50% and the fatigue life of the frame increased by 800%.
The design of cross beam integrating the installation of lift cylinder and bridge box into one prevents the torsional load and eccentric load in traditional design. The bridge box possesses the feature of replaceable bearing surface. The lubricated and sealed surface combines the beam into one, easily accessible and maintained.
An electric-wheel mining truck adopts the brand-new stress surrounding design to the bridge box, able to remove interior structure and reduce much weight. And the design of patented plate-type bearing in the taper tap reduces the contact pressure down to 1400psi (9653kPa) and lengthens the service life of the bearing.
In addition, a drag rod for easy lateral stability is provided for back axle.

Strong Body
The horizontal body bolster design of an electric-wheel mining truck can absorb more impact energy to reduce damage to the flank. Such a unique design also achieves a simplified structure and big reduction in weight compared with the traditional vertical bolster design.
