用混凝土泵和布料杆输送混凝土,在近几年得到了不断的发展。混凝土工艺方面的特殊要求是同使用这种机械相联系的。由于设计制造了布料杆,混凝土泵的推广使用才有了真正的突破。由于混凝土泵使用范围日益扩大,因此对磨损部件的寿命提出了很高的要求。混凝土泵和布料杆的使用是受某些经济上的考虑所约束的。在“埃森技术之家”举行的报告会上,专家们从科学上和实践上对这些问题作了引人注意的发言。
The use of concrete pumps and distribution posts to transport concrete has continued to develop in recent years. The special requirements of concrete technology are linked to the use of such machinery. Due to the design and manufacture of the distribution poles, a concrete breakthrough has been made in the promotion and use of concrete pumps. Due to the increasing use of concrete pumps, high demands are placed on the life of wear parts. The use of concrete pumps and distribution poles is subject to certain economic considerations. At the report meeting held at the “Essen’s House of Technology”, the experts gave a remarkable presentation on these issues scientifically and practically.
