With the launch of the MB122 and VTD121 Electro Thermo Controlled fixed screeds for its large tracked pavers, Volvo CE managed to grow its range of screeds.

New Volvo electric screeds heat up large scale paving W ith the launch of the MB122 and VTD121 Electro Thermo Con trolled fixed screeds for its large tracked pavers, Volvo CE is not only growing its range of screeds but empowering customers to produce the high-quality finish they come to expect, now in less time with less effort. Thanks to their ability to produce speedy, consistent and evenly spread heating from a single source of power, electrically heated screeds are an incredibly convenient solution. Powered by a 55kVA onboard generator, there is no longer a need for customers to refill gas bottles to heat the screed, as would normally be required with gas-heated screeds. The result is a fast start-up, maximum uptime and a more efficient work site. These fixed screeds are now available on the Volvo P6820D ABG, P7820D ABG and P8820D ABG models and benefit from an expansive paving width of 2.5-13m. They have been designed to lay everything from hot asphalt through to dry lean roller-compacted concrete and cement-bound materials, all the way to railway ballast and graded mineral mixes. Hot screed at top speed The new electric heating function enables start-up in just 40 minutes. When combined with one heated tamper bar and two heating elements per screed section for optimised heat distribution, precise thermo-controlled heating with an automatic temperature adjustment and individual temperature sensors per section, customers Electrically heated fixed screeds by Volvo Construction Equipment (Volvo CE) have now been introduced to make large-scale paving even more cost effective and to boost the productivity and efficiency of major road projects.

can be guaranteed a speedy and efficient screed heating process. Maximised pre-compaction Maximised pre-compaction is paramount to achieving a greater density in the finished mat, resulting in a longer-lasting pavement and lower operating costs. The new vibratory and tamping fixed screeds provide just that, delivering the smoothest possible finish for any job. Featuring variable vibration speed and tamper stroke, they can be specified with a single or double tamper bar solution. Volvo-fixed vibratory screeds with double tampers are the best partners for paving thick layers. Their double tamper technology delivers a 5-7% higher degree of compaction than with a single tamper and can achieve a 98% Marshall density, substantially reducing rolling work requirements and associated costs. They also provide the best possible even surface due to the feeding effect of the first tamper. Great flexibility With a crown adjustment of +4% to -2% and extension boxes to work across a variety of paving widths, the new screed solutions provide great flexibility for any job at hand. Vario extensions, with an extension range of 0.75m on each side, allow the screed to extend or retract as needed in order to adapt to irregular
