Q:How to choose concrete pump?
In order to ensure that the concrete pump has a larger amount of transportation, but also has a certain outlet pressure and the corresponding economic power, in the design of concrete pump, most of the constant power piston pump is used
Q:What are the types, classifications and specifications of concrete pump?
In accordance with the export pressure rating label, divided into low pressure pump (5MPa), medium pressure and high pressure pump pump (6-10MPs) (>10MPa)
Q:What are the layout requirements of concrete pump for building engineering?
The concrete pump shall be as close as possible to the casting site. In the use of cloth rod work, should make the casting parts as far as possible within the working range of the distribution rod, as little as possible to move the pump, that is able to complete the pouring.
Q:What are the fittings of concrete pump?
Hydraulic oil, eye plates, cutting rings (when the equipment reaches 5000 or more sides can be prepared) and so on
