In order to meet different requirements of our customers.SYMMEN provide not only the truck crane but also concrete truck.We have advanced technology and enough ability to design and manufacture all kinds of concrete truck,such as concrete pump truck and mixer truck.The concrete truck required at a construction site is a massive capital investment for any company and needs careful consideration. If the concrete truck is your need, we can provide the high quality at a cheaper cost.
A concrete pump truck is a machine used for transferring liquid concrete by pumping.
The principle behind the use of a concrete pump truck on a pouring job is quite simple. Concrete is moved from the pumping truck, to the form or area where it is needed. A concrete pump truck is, in its most prevalent form, a large, diesel-powered truck mounting a powerful pump, and an extendable, sectioned hose, or cylinder, and cylinder frame.
The extendable hose or cylinder booms on concrete pump trucks are usually from 17 meters (55.77 feet) to 61 meters (200.13 feet) in length, when fully extended. Depending on the size of the truck, and, therefore, the boom length, the boom can be folded into three to four sections, including the base section. The length of the boom, of course, determines how far away the truck will be placed from where the concrete is to be pumped.
A concrete mixer truck is a powered device that mixes cement with water and aggregate, such as sand or pea gravel, to make concrete. Concrete mixers range from the very large commercial mixing truck to the smaller, portable concrete mixer sometimes called a “mini mixer”. The mixer is comprised primarily of a motor, a rotating drum, and often a chute. Inside the drum, the materials used to make concrete spin around, mixing together evenly and remaining soft for application and forming.
A large commercial mixer truck is used for mixing and transporting large volumes of concrete for use on a building site. For smaller volumes of concrete, typically up to two cubic yards (1.83 cubic meters), a portable mixer is sufficient. A portable mixer is typically powered by electricity and sits on a base with wheels for easier transport. The rotating drum can be tilted down so that mixed concrete can be poured into a wheelbarrow.
The concrete is transported to the truck by a ready-mix concrete truck, commonly known as a cement mixer. The large drums on the cement mixing vehicle must be kept constantly rotating to prevent the concrete from setting-up, or hardening, prematurely. Small amounts of water are added during the mixing process as well for the same reason. Concrete pumping trucks, therefore carry no concrete, only the pumping mechanism, and sectioned hose lengths. Ready-mixed concrete is dumped from a cement mixer into the bay of the truck as the pump is running, thus emptying the pumping bay of the concrete as it’s dumped.
