What is a tandem roller?

tandem cylinder is a piece of machine used on roads and parking lots. The tandem cylinder is commonly referred to as a steam cylinder and consists of two very heavy and uneven steel cylinders mounted on the chassis, which is driven by steam, gasoline or diesel. The tandem cylinder is used to smooth and compact asphalt or blacktop before cooling and solidify. Steel drums or rollers on which the machine runs are often cooled by a stream of water to prevent the road from sticking into the cylinders.

In addition to being heavy, many tandem war units also contain a vibrating unit on board the machine. The vibrating rollers help to thicken the sidewalk as a heavy tandem roller passes over it. The tandem cylinder works at very slow speeds and is a machine that requires skill in operation to ensure that each pass slightly overlaps the pass in front of it. By offsetting any passage, the roller operator is able to maintain a even thickness to the surface and avoid whatKoli immersion or high-spots.

The early versions of the cylinder relying on the engine driven by steam to move large machines. This led to the common name of the cylinder known as a steam cylinder. The name of the steam cylinder is often connected to the machine today, which is partly due to a pair that is created on the rollers when using the device. This steam is the result of water, which is used to cool and lubricate cylinders coming into contact with a very hot sidewalk. The steam is created by this contact and therefore the name of the steam cylinder remains intact.

While today the steam drive drive system is very unusual, modern machinery is largely driven by diesel. Some smaller units use petrol engines and battery versions are beginning to appear on some construction sites. Many models use two separate energy systems. Tandem roller driven by diesel can also useT battery -sided vibration engine.

While huge steel cylinders are very difficult in themselves, most of the tandem war units use water to add weight to the rollers. Each cylinder is equipped with a sub -construction bungle that can be removed. The water is then placed inside the cylinder by placing the hose in an open bung. Once the cylinder is filled with water, the bung is replaced and the unit becomes functional. The weight of the water helps the cylinder to thicken the sidewalk.
