As a means of modern construction, the concrete pump truck has an irreplaceable role in speeding up the construction progress, shortening the construction period and reducing the construction cost with its characteristics of large conveying capacity and fast conveying speed. So what should we pay attention to in the purchase and use of concrete pump truck?
Buy well-known brands, product quality is guaranteed. Through the sales company of the production enterprise or the sales office of the production enterprise in various places, to ask for access to the identification certificate of the purchased product, type test report, inspection report of the special vehicle inspection project and the motor vehicle catalog number, quality system certification, etc., it is best to send a special person to the production enterprise to inspect its production, management and quality, as the basis for selecting the product.
According to the situation of undertaking the project and the size of the construction project of the equipment, the length of the cycle and the frequency of transfer, the maximum pumping volume, the length of the cloth arm, the parameters of the cloth arm and the appropriate chassis are determined. Inspection of product quality should be from the outside to the inside, the first is the appearance of modeling, painting, weld steel structure, platform, railings, etc., is smooth, beautiful and smooth. Then step by step into the interior, chassis engine, transmission, distribution bridge, main hydraulic components, pumping system, distribution arm, rotary mechanism and rotary support and other components of the performance quality.
3. Investigate the use performance of the product, the stability and flexibility of each part of the action, whether the extended fabric arm and the recovered fabric arm have abnormal shaking, whether the chassis driving, turning diameter, approach Angle, departure Angle, minimum ground clearance, etc., meet the passing requirements, whether the economic indicators such as the fuel consumption rate of the engine are reasonable, and whether the remote control operation is reliable and stable. The products of self-made fabric arms should also carefully understand the manufacturing quality of their structural parts. In order to reduce the weight of the cloth arm, bottom frame and leg, the steel should be made of carbon steel with high-strength fine-grained structure (tempered thin steel plate), and the welding process requirements are very strict, otherwise there will be very serious problems such as weld cracking.
4. Check the safety and environmental protection requirements of the products, and check whether the special vehicle inspection items, braking performance, emission indicators, noise limits meet the requirements of the standards. Investigate whether the after-sales service network of the supplier can meet the timely service, as well as the service quality, service level, and the ability of timely supply of spare parts. Understand the supplier's commitment to operational training and maintenance training for customers' drivers, operators and maintenance personnel.
5. When purchasing products and acceptance, it is necessary to check the supply list and relevant information in detail, the certificate of conformity, the instruction manual, accessories, accessories, maintenance kits, etc., and whether the purchase procedures should be complete. The purchasing unit shall select a special person who has been trained by the supplier and qualified drivers, machine operators and maintenance personnel to operate and maintain according to the procedures specified in the operating instructions.
