SUB FEATURE
With its offset position , the drum can pivot up to 30 degrees and reach 30 inches below the mounting point . The host machine can drive safely on flat ground while the attachment arm extends to the furthest , steepest edge of sloping road shoulders and ditches . This allows the roller to easily compact slopes at various angles that would flip a traditional compaction machine .
The increased safety offered by the offset roller design reduces workers comp claims , lowers insurance premiums and enhances a contractor ’ s overall safety ratings — a key factor for contractors in a competitive bidding environment .
Further , shifting the drum to an offset arm attachment doesn ’ t just drastically improve safety , it also unlocks a host of other benefits .
Because of the rigid design of traditional compaction rollers , and the stability issues working on a slope , operators tend to drive at a slower rate resulting in a slower compaction rate .

Maximum Capabilities in a Compact Package
Although safety is the top priority on any jobsite , the efficiency and quality of a job along with equipment versatility also prove critical . Compaction roller attachments can increase the efficiency and versatility of a contractor ’ s existing fleet by allowing them to work on a variety of road construction and utility repair projects , all with the equipment they are already familiar with . The attachments effectively compact a range of materials , from gravel , stone and topsoil to even hot asphalt mix .
With the high infrastructure demand and scarce , inexperienced workforce , ease of use — in terms of equipment — is key to a project ’ s overall efficiency . Some offset compaction attachments incorporate remote controls , combining safety with an intuitive operation that is easy to learn , and allows the operator to adjust the height , angle , extension and compaction adjustments all from the comfort of the host machine ’ s cab . While a compaction roller attachment may not achieve density as quickly as a ride-on roller on a flat roadway , it excels in a sloping ditch or trench which places an operator in a hazardous position . Because of the rigid design of traditional compaction rollers , and the stability issues working on a slope , operators tend to drive at a slower rate resulting in a slower compaction rate . Alternatively , the offset compaction roller attachment allows an average vibratory density of 106.5 pounds per cubic foot in just one pass on a typical gravel shoulder . Efficiency is not only seen through the work on the job but also by reduced transportation challenges . The compact design of compaction attachments allows it to fit on any common trailer along with the host machine — and other core attachments — and be towed by a standard pickup truck . No heavyhaul trailers or permits are required .
Additionally , compaction roller attachments can offer contractors the ability to expand their application capabilities and win more bids by incorporating an adaptable system into their business model . Compaction roller attachments can be purchased in a variety of interchangeable drum widths , ranging from 2 to 4 feet , providing heightened adaptability . To get the same benefit with traditional compaction machines , contractors would have to purchase multiple self-propelled units , all with engines and trans- www . callape . com [ 20 ] 1.800.210.5923
