This Dynapac DR7X is a used walk-behind compactor — also commonly referred to as a rammer or tamper — a type of machine designed to compact soil, gravel, and other materials in trenches, confined areas, and spots inaccessible to larger plate compactors or roller equipment. Dynapac is a well-established manufacturer of road construction and compaction machinery, supplying equipment to contractors in earthworks, utilities, road building, and civil construction worldwide.
Power comes from a Honda GXR 120 engine rated at 3.6 horsepower, drawing from a one-gallon fuel tank and consuming approximately 0.2 gallons per hour — an efficient figure that reflects the machine's suitability for sustained operation on worksites where refuelling may be infrequent. The compaction plate measures 13.2 inches by 11 inches, concentrating impact force onto a relatively narrow footprint, which is well suited to trench work and tight corners.
The machine delivers an impact force of 3,822 pounds at a vibration frequency ranging from 600 to 710 vibrations per minute. That combination of high impact force and adjustable frequency allows the operator to adapt compaction intensity to different soil types and layer depths, making the machine useful across a range of compaction tasks from backfill to subbase preparation.
This unit was manufactured in 2023 and is offered in used condition from Iowa, USA, at a price of $2,950.
