New & Improved Cummins Qsb4.5 Powers Up To 173 Hp for Tier-4 Final Cummins Inc. has announced that the next-generation QSB4.5 engine will meet Tier-4 Final near-zero emissions standards with top-rated power increased to 173 hp (129 kW) and a higher peak torque of 520 lb-ft (705 N•m). The 4-cylinder, 4.5-liter engine is performance-enhanced with a Cummins VGT(TM) Variable Geometry Turbocharger, enabling the higher ratings of the QSB4.5 to reach performance levels previously associated with a larger 6-cylinder engine. For the QSB4.5 lower ratings – down to 121 hp (90 kW) – the VGT technology improves transient response on a fuel-efficient basis. For equipment operation, this means a stronger, faster response to increasing load demands compared with Tier-4 Interim engines.

Featuring five mandrels to bend rebar into a variety of angles and for repeating bends, the rebar bender is mounted on the left Bob-Tach mount. In addition, operators can start and stop their idled loader or Toolcat utility work machine from outside the cab. Allowing for easy, safe operation of the rebar bender from outside the cab via a remote attachment control (RAC), the rebar bender is capable of bending rebar up to a No. 6 grade to 200 degrees. A wired remote control starts and stops the rotation of the bend pin with an optional bar stop that can be set at almost any angle for an automatic stop and a repeatable angle setting. The unit weighs 330 pounds with a height of 20.1 inches, width of 23.5 inches and depth of 16.7 inches. It is ideal in ground conditions that are soft, rough or muddy. The rebar bender is compatible with Bobcat skid-steer loaders, compact track loaders, allwheel steer loaders and Toolcat utility work machines.

The modular design allows configuration as a two-track (SP 82i) or four-track inset paver (SP 84i), or offset for large sections (SP 81i). A modular inset mold system allows for paving slabs with a central crown of 12 to 26 foot width. Steering modes, which are computer controlled, are available for back-straight, rotate, crab and coordinated positions. In addition, the AutoPilot stringless control system enhances Wirtgen's paver line as it can be used with Wirtgen's SP 15 and SP 25 concrete slipform pavers and the SP 81i offset machine.
