Liebherr says its new R 9100 mining excavator sets standards in the 100-ton class for productivity, reliability, and cost efficiency. The excavator’s V12 engine has an output of 565 kW (757 horsepower) and, combined with the efficient hydraulic system, provides high digging and breakout forces. The specially shaped 6.8-cubic meter bucket increases penetrating power and fill factor. A wide catwalk makes access to the various mechanical assemblies easy. Other features include an operating weight of 110,100 to 114,000 kilograms; a machine monitoring and control system; and a new cab design.
Screening and Crushing Solutions says its TC1885 is “the world’s largest-ever mobile cone crusher.” The machine is powered by a 27-liter, 875-horsepower, twin-turbo, V12 Caterpillar engine. The crushing unit weighs 65 tonnes (71.7 tons) on its own. The close-side setting can vary from 65 millimeters down to 15 millimeters. Four concave options are available with feed openings of 500, 360, 240, and 180 millimeters (19.7, 14.2, 9.4, and 7.1 inches). The crusher, originally manufactured for a mining and demolition company in Australia, will be available globally.
Titan Trailer’s new extruded aluminum, V-Floor trailer combines the lightweight strength of an aluminum Thinwall body with the simplicity and stability of the latest live-floor system from Keith Mfg. Co. The trailer is said to be one ton lighter in weight, allowing it to carry up to 2,000 pounds more payload. Additional features include a low ride and narrow body for reduced wind resistance and increased fuel efficiency; a hydraulic tailgate that lifts up and out of the way; all disk brakes for shorter stopping distances; and a handheld remote control for controlling the unloading system, V-Plow, tailgate, and tarp from inside or outside of the truck.
Superior Industries says its new 170-foot TeleStacker conveyor is quick and easy to relocate and requires less space because of its low-level loading hopper. The telescoping radial stacking conveyor has a 200 kW gen-set unit for onboard power and is said to require less equipment to transfer material, minimizing the number of loads in a transport. The conveyor is available in 110-, 130-, 136- (low profile), 150-, 158- (low profile), 170-, and 190-foot models with production capacities ranging from 500 to 5,000 tons per hour.
Keep a cool head
The Cool Hard Hat, manufactured by a company with the same name, uses two battery-powered fans to blow 8 cubic feet of air across the top of the wearer’s head and neck. This airflow provides cooling as it moves the heated air away from the head, allowing the body to cool itself naturally. Benefits include more comfort, less perspiration on the head and neck, and a reduced risk of heat stress or heat stroke. The Cool Hard Hat is said to lower the temperature inside the hard hat by as much as 20 degrees.
Nook Industries says its NIA Acme and Ball Screw Series linear actuators offer compact size configuration and enhanced IP65 protection options against solid (dust, airborne particles, etc.) and liquid (rain, water spray, etc.) elements. Design elements that contribute to the high IP ratings include a steel extension tube, powder metallurgy gears, and aluminum alloy housing. The series offers a standard 110/115/230 VAC single-phase, split-capacitive motor that delivers a 25-percent duty cycle; the ND8 Ball Screw Series is also available in a 12/24V DC motor option.
Durable, powerful generators
Subaru say its new line of SGX Generators features durable construction and Subaru EX overhead cam engines, making them rugged and powerful. The SGX3500 generator features a 7-horsepower EX21 engine, delivers a maximum output of 3,500 watts, and has a run time of 8 hours at the rated load. The SGX5000 features a 9.5-horsepower EX30 engine, offers a maximum output of 4,900 watts, and runs for 9.4 hours at the rated load. The SGX7500E features a 14-horsepower EX40 engine, provides a maximum output of 7,300 watts, and offers a continuous run time of seven hours at the rated load.
J.R. Merritt says its new XL-VNSO Hall-effect joystick controller is enhanced with long-life, non-contacting Hall-effect technology. The 1-, 2-, and 3-axis joystick is said to provide precise proportional control of electro-hydraulic proportional valves commonly found on off-road mobile equipment.
