Bomag

The new mid-size Bomag BW145-3 series single-drum vibratory rollers deliver improved compaction force, gradeability and tractive effort for greater productivity on both granular and mixed soils. The series includes three models: the BW145D-3, BW145DH-3 and BW145PDH-3. The BW145D-3 and BW145DH-3 are smooth drum models, while the BW145PDH-3 is a pad foot unit. All models offer a maximum vibration frequency of 2,040 vibrations per minute, compared with 1,980 vpm on the models they replace.

Ron Swanson, field supervisor for Valley-Rich Co., Chaska, Minn., has these comments: “It's a small roller [BW145PDH-3], but it has the packing ability of the big ones. It seems to really pound. The unit is very maneuverable. It allows us to get in and compact right away next to structures. It also offers very good visibility; you can see all around the machine.”

Multiquip

Rammax's new P33-HHMR-BD from Multiquip is the only walk-behind roller in the industry with a leveling blade. The product has dual compaction settings that allow the operator to easily change amplitude, frequency and compaction force, making the roller effective in more granular soil applications. The roller also has two drum widths — 33 and 24 inches for maximum flexibility and superior performance in shored trenches and against trench walls and sides. It generates impact forces of 18,500 and 12,150 pounds.

Allied Construction Products

Allied Construction Products introduces the NT 8900 compactor. The compactor focuses on narrow trench soil compaction and provides more with less. Appropriately sized to mount on loader/backhoes, the compactor produces the same compaction power as a 24-inch wide compactor but does it with a narrow frame and 16-inch base plate. As a result, the product reduces digging time and the amount of material to be excavated.

“I don't hear about problems with them [NT 8900 compactors],” says Shawn Klumb, purchasing manager for Arby Construction Inc., New Berlin, Wis. “The less I hear about them the better they are. From what we see, the compactors are maintenance-free.”

Ingersoll-Rand

Ingersoll-Rand introduces three new models of BX series single-direction, vibratory plate compactors — BX-60WH, BX-80WH and BX-120WH. Key features of the new BX series models include a more compact vibratory plate compactor design that offers maneuverability on the job site, flip-over handles that provide ease of operation and better compaction in confined areas and the only ratcheting throttle design in the industry for improved control around job site obstacles. These units come standard with a 50-percent larger removable water tank that provides increased operating intervals and allows the operator to take the tank to the water source, rather than the previous method of bringing the water to the unit to refill.

Jason Pasquetti, owner of Ray Pasquetti Construction Inc., Granite Bay, Calif., appreciates the BX-80 single-direction vibratory plate compactor for its ability to condense granular soils and crushed aggregates. He says the sprinkler system on his BX-80 allows him to use the compactor in hot mix asphalt applications as well.

Wacker

Wacker's premium WP plate series is among the first Wacker products to feature its new state-of-the-art 4-cycle engine and 2-year complete bumper-to-bumper warranty. The new WM 70, 6-hp, 4-cycle engine powers the WP 1540 and WP 1550 plate series. The engine features a case hardened steel, chain driven overhead cam that provides great reliability and long engine life, and the high-efficiency pent-roof combustion chamber increases horsepower and torque. The WP plate series is designed with the CAD/CAM ductile iron base plate and heavy-duty shock mounts, which significantly reduce vibration to both engine and operator while maintaining maneuverability.

Rick Frederick, yard manager for The Bentley Co., Milwaukee, has this to say about the WP 1550 vibratory plate, “I like the size of this plate. It's compact and can still do the job. This unit is definitely comparable to the other Wacker plates we own. There is less force required to pull the starter rope, and it seems to run quieter. It has a lower tone to it.”

M-B-W

Powered by either a 2.4-hp Robin or a 3-hp Honda, the R420 percussion rammer from M-B-W features a low center of gravity, noise attenuating 4.6-quart fuel tank, 4-ply steel and fiber reinforced bellows, cool running delivery system and a patent-pending anti-vibration guiding handle (R420H, only). The 125-pound rammer delivers up to 700 blows/minute at 3,100 pounds/blow. The rammer can be optionally equipped with digital tachometer, which advises operators as to whether the rammer is running within optimal performance range.

MMD Equipment

MMD Equipment's PC-800 vibratory plate compactor was designed with features to increase its durability as well as increase operator productivity and operating ease. The plate runs on a Honda engine that features an electronic ignition for easy starts, cast iron sleeves, forged crankshafts and twin bearings for durability and low oil shutdown for protection. The abrasion resistant, alloy steel plate can be rotated 180 degrees for even wear and long life. The plastic water tank, reinforced piping and low profile nozzles prevent rust and clogging of the sprinklers.

Stone Construction Equipment

Stone Construction Equipment adds a 48-inch heavy-duty trowel to its line of Smooth Operator power trowels. The trowel model CF484 is available with three engine options: 11-hp Honda, 11-hp Robin or a 13-hp Honda. The trowel operates at a faster blade speed, suitable for quickly burning in slabs. It features an extra long adjustable handle for better control with less effort.
