Making concrete work more effective


Concrete Pump Concrete Pump

Until the early 20th century, concrete was mixed on the job site and transported from the cement mixer to the formwork, either in wheelbarrows or in buckets lifted by cranes which required a lot of time and labour.

A concrete pump is used to transfer liquid concrete from the truck or semi-trailer directly to the construction site. Also known as a boom concrete pump because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete accurately.

The concrete pump truck perfectly combines the functions of driving, pumping and distributing the concrete together with the boom which has the functions of folding and turning. The boom is flexible and fast, while the support leg occupies a small space, which means that the whole vehicle is easy and flexible to move.

Demanding hydraulics

The concrete pump trucks needs to be durable, reliable and effective. This makes high demands on the hydraulic components, for which Sunfab’s renowned quality and high-performance hydraulic pumps and motors are the perfect match.

Sunfab offers several options to suit your specific system needs
