Atlas Copco’s SBU 220 hydraulic breaker features a patented one-piece housing construction — a solid-body concept that integrates the percussion mechanism and guide system into one single block of steel. The one-piece housing is designed to have fewer components to maintain and to provide greater return on investment. The breaker is intended for carriers ranging in size from 6,150 to 13,230 pounds and features an operating weight of 494 pounds and a tool shank diameter of 2.56 inches.

Highly mobile screen plant

Deister Machine says its new, portable, heavy-duty horizontal screening plant with feed conveyor is highly mobile and easy to transport from site to site. Units are available in 6- x 20-foot and 8- x 20-foot models, as well as a number of custom configurations. The plant features a 42-inch screen feed conveyor (48-inch on the 8-foot unit); walking beam tandem-axle suspension; access ladders and walkways on both sides and front of the screen, with hydraulic folding on one side; centralized grease points; chutes and hoppers lined or made from AR 400 plate; a 60-inch undersize conveyor below the screen (84-inch on the 8-foot screen); 30-inch, motorized head-pulley cross conveyors (36-inch on the 8-foot screen); and self-cleaning, wing-type tail pulleys.

Unattended weighing/data management

Cardinal Scale’s new RE series outdoor unattended weighing systems can be configured to meet the customer’s specific operation with a variety of software and hardware features. Depending on the specific application, the system will incorporate the Cardinal model 225 Navigator weight indicator or the model 825 Spectrum with full-color graphics touch-screen display. The driver is prompted through the entire weigh transaction for required information, which is recorded in the scale house on WinVRS truck management software.

Refined dozer design

Caterpillar says its new D11T dozer and D11T CD (carry dozer) set the standard for productivity, durability, reliability, safety, and operator convenience with design refinements that include enhanced auto shift, a dynamic inclination monitor, automatic climate control, and available automated ripper control. Blades range in capacity up to 57 cubic yards, operating weights range up to 248,456 pounds, and the C32 engine meets Tier 4 Final emissions standards. Both units feature an “OK-to-Start” system that electronically checks critical fluid levels.

Single-point ripper bucket

Leading Edge Attachments’ patented single-pointed ripper bucket is a ripper/bucket combination designed for use with excavators and backhoes. It is said to allow the operator to rip rock, coral, or frozen ground with maximum breakout force, pry out and carry stumps or cradle boulders, rip a clean narrow V trench, or scoop and load material. The unit is manufactured in the USA with high-strength Hardox 400 steel slabs for abusive or cold-weather conditions.

Primary/secondary scraper shares one mounting point

Superior Industries says its new Exterra SFL dual belt cleaner is the first ever primary and secondary belt-cleaning system to share the same, common mounting point. The unit features a tensioning system that creates pressure that is set once, for the life of the blade, during installation. The company says the belt cleaner is designed to nearly eliminate material carry-back from the top cover of conveyor belting after it passes over the head pulley. The belt cleaner is designed to accommodate head pulleys with diameters of 12 to 20 inches and belt widths of 18 to 60 inches.
