BOMAG’s four-cycle engine tampers
Designed with the operating convenience of a four-cycle engine, both the BT60/4 and BT65/4 model tampers maintain the high stroke and impact force of a two-cycle model, according to the manufacturer. They can be transported in a horizontal position without concern for oil contamination of the cylinder, muffler, carburetor or air filter.
The tampers are used for compacting cohesive, semi-cohesive and granular soils in highway patching, as well as backfill around foundations and footings, reinstatement in trenching applications, and utility and cable backfill applications. The tampers’ four-cycle engines produce low noise and emissions, so the units work well in residential areas and confined trench work, according to the company.
The BT60/4 weighs 137 pounds and delivers up to 3,035 pounds of impact force with a maximum compaction depth of 22 inches. The BT65/4 weighs 150 pounds and delivers up to 3,642 pounds of impact force with a maximum compaction depth of 26 inches. The maximum travel speed of both models is 66 feet per minute, and they produce 600 to 708 impacts per minute. The tampers have a standard operating width of 11 inches.
Four interchangeable shoe sizes (6, 9, 11 and 13 inches) are available as optional equipment, as well as tamper shoe extensions with 4- and 6-inch working widths. For simple field replacement in utility applications, such as laying cable and installing underground sprinkler systems, the 15-inch-long extensions use the same bolt pattern as factory-installed shoes.
The tampers have an engine protection cover for durability and come with a dual air and fuel filter system. A low-oil alert system reduces maintenance concerns and promotes equipment reliability by preventing the tamper from operating with an inadequate lubrication level. A float gauge in the engine crankcase checks the oil supply when the operator attempts to start the engine. When the oil level is low, the gauge activates an electronic warning device that stops the engine from starting.
- When transported in a horizontal position, there is no oil contamination of the cylinder, muffler, carburetor or air filter.
- Low oil level activates an electronic warning device that prevents the engine from starting.
- Tamping foot construction is honeycomb polyethylene for shock absorption, stability and smooth operation.
