U.S. Construction Machinery Fair (CONEXPO) (Las Vegas Construction Machinery Exhibition) grandly opened on March 4, 2014, which will last for five days until March 8. CV122U single steel wheel vibratory roller made its debut in this event, it is a star product from XCMG road roller family, which is a leading brand in North American Market for many years, The roller is specifically designed for the North American market, it not only meets the performance indicators of International Standard, but also represents the most advanced technologies in domestic market.
CVl22U is a midsize modeling hydraulic drive vibratory roller featuring more excellent performance and stylish elements, which is developed on the basis of full hydraulic steel wheel vibratory roller XS120 which had the largest export volume in China. As one of the representative products of full hydraulic vibratory rollers of XCMG, its compaction performance, driving performance, operation performance, reliability, maintainability performance and other aspects all represent the highest level in the field of domestic rollers. In aspect of vision field, its rear vertical shaft is moved to one side, with all-glass design in the front and back of the cab, so it has no shading defect in the front and back direction, providing extraordinary vision for the driver. In aspect of operation, it uses all-hydraulic drive, with simple and easy operation. The manipulation meter box is in accordance with ergonomic principles, equipped with suspension seat and car recorder, which make the cab more comfortable. Meanwhile the standard air conditioning makes the operating environment more comfortable and pleasant. The model adopts a dual-band and dual-amplitude vibration system, scientific and rational static linear load and exciting force configuration, so as to ensure effective compaction of different types of materials with different thickness layers. Optional welded bump vibration wheel or fabricated bump vibration wheel also expand the product use range and bring over-valued return to customer as one machine can be used in two ways. In the electrical system utilizes imported parts with better waterproof, dustproof, vibration proof better to ensure reliability of electrical systems. Meanwhile, it also uses the imported maintenance-free battery with higher starting current and strong adaptability.
In terms of safety protection, the product has the following features: First, it has three braking systems which are driving, parking and emergency braking to secure the road safety. Second, the cab has anti-roll features so as to ensure the safety of personnel. Third, it has non-slip ladder pedal; the cab’s tread rubber flooring can effectively prevent the operator’s accidental slipping. Fourth, the hood supporting system is equipped with safety protection devices aiming to ensure the safety of maintenance personnel, which is convenient and reliable. Fifth, it is equipped with a rotating alarm lamp, reversing buzzer for guaranteeing the traffic safety. The model also has excellent maintenance performance. The alarm device on the dashboard provides maintenance and repair information at any time, thus avoiding devices working with “diseases”, preventing damages to equipment, and reducing downtime. The hood opening in the front has a large turning angle, with maintenance parts within people’s reach; in the cab, people can control the independent electro-hydraulic control and support system to allow the hood to be safely parked in any location during the lifting process, with easy maintenance. It uses water-cooled turbocharged engine imported from CUMMINS Company, with reliable performance, great power reserves, low fuel consumption, and low noise. Its emissions meet Euro 2 standards. It also adopts the imported heavy drive axle with NO-SPIN differential mechanisms, with wide base tire as the drive tire, which has a large contact area with the ground. Therefore, the driving performance has been greatly improved, so as to ensure that the roller can have a good performance in a variety of conditions. It also uses a closed anti-skid hydraulic drive system consisting of imported heavy duty variable motor, so as to ensure that the drive roller has good driving performance and high climbing ability.
As we know that, XCMG road roller products which represent “Chinese made construction machinery manufacturing enterprises” have accumulated sales of more than 3000 units in nearly 30 years since the first roller entered the United States market in the 1990s. XCMG has become the largest Chinese road roller engineering machinery manufacturing enterprise stationed in the United States market and an active backbone participant in the roller import market in the North America.
