Can the Hanma Power Engine still play like this? Learn about BMW Black Technology in minutes

As the most mainstream construction machinery exhibition in China, the Shanghai BMW Show held on November 27-30, 2018 focused on the latest products of major construction machinery companies. After a lap of browsing, the various types of engineering machinery of various types have long been seen. Simply, it’s better to pick a heavy product “to find out” when you visit the show. So on the Hualing Xingma booth full of heavy truck products, a new type of engineering vehicle caught the attention of the Chinese truck network reporter. It is a 56-meter concrete pump truck from Hualing Xingma.

Why do you focus on this product, mainly because traditional vehicle manufacturers rarely encounter special vehicles such as concrete mixers and pump trucks. However, Hualing Xingma is an exception. Before becoming a vehicle manufacturing enterprise, Hualing Xingma's identity is a special car topping manufacturer. In particular, the concrete mixer truck that everyone knows is the strength of Hualing Xingma. The concrete pump truck launched this time is also considered to be the return of Hualing Xingma.

As we all know, a concrete pump truck is a device for pumping concrete and integrating the pumping system and the boom system on the chassis of the vehicle. The working principle is that the pumping system utilizes the power of the chassis Engine to pressurize the concrete in the hopper into the pipeline and pump the concrete to the pouring point through the extension of the boom. However, to complete the complicated process of these columns, it is necessary to complete There are corresponding equipment to support. Take Hualing Xingma 56m concrete pump truck, which is mainly composed of vehicle chassis, power transmission device and pumping mechanism (pumping agitation device, distribution device and auxiliary device are collectively referred to as top loading pumping mechanism)

In terms of chassis, Hualing Xingma concrete pump truck adopts Hualing Heavy Truck 8X4 truck chassis, which is the same as the chassis of Hualing Xingma 8X4 mixer truck. Moreover, the structure has high strength and strong carrying capacity. After a large number of users have actually used it, it has done a lot of improvement work, and the maturity is relatively high, especially suitable for transportation and modification of heavy-duty equipment. In terms of power selection, Hualing Xingma specially matched a CM6D series 430-horsepower engine from Hanma Power. In this regard, in fact, people may have some doubts. The main working characteristics of concrete pump trucks are not transported by cargo. Why, why is it equipped with a engine with such a strong power?

In fact, the engine of the concrete pump truck is not only used to drive the vehicle, but its more important function is to rely on the power transmission device to pump the concrete to the pouring point. The power of Hualing Xingma 56m concrete pump truck is transmitted to the hydraulic pump unit through the power transfer box. Then the hydraulic pump pushes the piston to drive the concrete pump to work. The concrete rod and the conveying pipe on the pump truck are used to send the concrete to a certain height and distance. It can also be seen from this that the engine's dynamic performance will directly affect the pump's working ability and working efficiency. Therefore, after using the Hanma Power 430-horsepower engine, the Hualing Xingma concrete pump truck is based on excellent power performance. Both work efficiency and pumping capacity have increased significantly. Moreover, the ultra-low fuel consumption level of the Hanma power engine can also be a great tool to reduce the cost of using concrete pump trucks.

Safer and more practical, concrete pump trucks also have black technology

As for the pumping mechanism of the upper part, in order to improve the practicability and safety and stability of the pump, Hualing Xingma has carried out a series of technical upgrades. For example, the boom of the pump truck uses high-strength steel with a yield strength of 900 MPa, which can ensure that the boom has sufficient strength to support the pumping pipeline under the premise of reducing its own weight. The hydraulic system of the pump truck adopts a closed hydraulic mechanism, and the commutation of the pumping material is transmitted through the Rexroth bidirectional variable displacement pump. The advantage of the main cylinder is that the impact of the main cylinder is smaller and the commutation is more stable in the reversing direction. At the same time, the impact on the boom is also reduced, and the working vehicle is more stable and safe. Moreover, the front legs of the two-section telescopic X-shaped structure can be retracted easily in a small space, improving the convenience of operation.

In terms of control system, unlike the ordinary electrical controller installed in the rear of the vehicle, the Hualing Xingma 56-meter concrete pump truck was redesigned to facilitate the installation of the electrical control cabinet and the multi-way valve. And the highly integrated controller and CAN bus control also enables automatic diagnosis and automatic discharge of faults, reducing the failure rate during pumping operations. In addition, Hualing Xingma parts are derived from excellent supplier chains. For example, the German Spoel Power Transfer Box has stable performance and reliable quality, which also provides a strong guarantee for the reliability of the whole vehicle.

In fact, looking at the 2018 Shanghai BMW Show, the whole vehicle manufacturer represented by Hualing Xingma is not satisfied with producing only commercial trucks in the traditional sense. They are more concerned with mastering core technologies, just like Valin. The full range of product coverage of Hanma Power, Hanma Transmission and Hanma Axle owned by Xingma also ensures that Hualing Xingma will gain an advantage in the future commercial vehicle market competition.
