Concrete pumps play a crucial role in construction. To ensure construction safety and efficiency, operators need to focus on four core points. Firstly, after the construction is completed, thorough cleaning is required. The concrete in the hopper and pipes should be drained and flushed. When flushing the pipes with compressed air, no one is allowed to stand within 10 meters of the outlet end. At the same time, the collection of cleaning materials and the removal of solidified concrete should be done well. Secondly, pay attention to daily maintenance and lubrication. Before use, check the condition of electrical equipment, instruments, hopper filters and safety protection devices. After operation, add lubricating oil to each lubrication point and apply oil for rust prevention. Thirdly, standardize the positions of control switches. All control switches should be returned to the neutral (or off) position.
