Asphalt Paver Screeds Hydraulic Extending Screed Extension Mechanical Extending Screed Extension
The extending screed is an important component on an asphalt paver that allows the screed system to be adjustable to varying paving widths. The extending screed attaches to the ends of the main screed plate to effectively increase the total screed width. It consists of steel screed plates that are connected to the main screed, screed heaters and vibrators to match the main screed system, and a hydraulic mechanism to extend and retract the screed plates. The key purpose of the extending screed is to provide flexibility in paving widths without requiring an entirely new screed system for each width. By using interchangeable extending screeds of different lengths, a single asphalt paver can pave roadways of many widths. This allows contractors to use a single machine for various paving projects to improve cost and time efficiency. The extending screed attaches on one end to the main screed plate of the paver, and on the other end to a telescopic arm that can extend and retract. Screed plates equip the extending section and match the main screed, with heaters, vibrators, and a tamping bar to mate with the main screed components. When fully extended, the extending screed seamlessly connects to the main screed to provide a uniform and continuous screed surface across the full paving width. The integration of compatible screed components in the extending section allows for continuous, uniform pavement smoothness, density, and texture across varying widths.
Crafts is able to provide the perfect fitting asphalt paver extending screed for almost all the popular brand asphalt pavers, such as VOGELE, DYNAPAC, CAT etc. The extending screed enhances the adaptability and utility of asphalt pavers. With the ability to widen and narrow the screed system to match the required paving width, a single asphalt paver gains far greater flexibility and range. This ability provides cost and time savings to contractors and road builders. The extending screed, along with the main screed plate assembly, helps the asphalt paver tackle a wide range of paving projects. There are two type extending screed, one is the hydraulic type which enables to create varying pave widths between 1.1m and 9.5m, its advantage is enormous flexibility for different pave widths; the other is the mechanical fixed-width type which is mainly used for long-term building projects with constant, large pave widths and large radii since they are able to manage pave widths between 2.5m to 16m using additional screed attachments.
