XCMG 303 tire roller engine type
Towed vibratory compaction can effectively all kinds of soil and rock fill, suitable for modern highways, airports, seaports, embankment, dam, railway and mining engineering construction in the roller device many bump pressure roller. Due to the bump like sheep foot so called sheep foot roller, sheep foot roller. The shape of the convex block is a sheep foot shape, a cylindrical shape, a square column shape, etc.. The roller shaft is supported on the bearing of the traction frame and expands the application range. Can be filled with water, sand or sand to increase the weight of rolling drum. Comb scraping plate is arranged below the frame drum before and after, to clear the bump between sticky mud block. Towed by a tractor dragging sheep foot roller. Self-propelled kneading or tamping roller. Kneading unit pressure, the filling evenly, a tamping effect, degree of compaction, especially for hard clay, suitable for compacted clayey soil and gravel layer. Especially for hard clay, the convex block has stirring, kneading and tamping action, there is tamping effect, so that the packing is even, the upper and lower layer bonding good, avoid delamination. Widely used in subgrade, cushion and dam compaction. The self-propelled kneading drum can also be installed in the vibration device, made of vibrating compaction roller, the vibration force increases the compaction effect, can be filled with water, sand or sand to increase the weight of rolling drum. Expand the scope of use. The main technical parameters of the machine for kneading weight and unit pressure. Due to compaction bump shape so that the 1. sheep foot kneading on roads and railways, dams, airports, factories, residential buildings. 2. cement plant waste, ash, coal and other bulk stacking site compaction. 3. compaction of earth and stone with relatively wide water content. 4. compaction of rock, clay, and expansive soil. 5.. Flame retardant compaction of opencast coal seam.
The road roller belongs to equipment in construction machinery category, widely used in Embankment Compaction of highway, railway, airport runway, dam, stadium and other large projects, can crush sand, semi viscous soil, the stability of subgrade soil and asphalt concrete pavement. The utility model is suitable for various compacting operations of the static pressure roller by the gravity action of the machine itself, so that the compacted layer is permanently deformed and compacted. It is divided into two types: steel wheel type and tyre type. Grinding wheel grinding, grinding groove structure light and kneading etc.. The most common application of light milling is mainly used for compaction of surface layer of road vibratory roller. With mechanical or hydraulic transmission, the utility model can concentrate the compacted part of the protruding part, and has high compaction and smoothness, and is suitable for the compaction operation of the asphalt pavement.
