1,200 mt and a top height of 188 m for the nine-axle LTM 11200-9.1. Compact by design, their advantages include their versatility and mobility, with travel speeds of up to 80 km/h (50 mph), the company stated. Terex's Aussie Pick-and-Carries Terex's Australian operations have developed pick-and-carry cranes, which, the company told E&MJ; , offer strength and easy operation to pick up heavy loads while having steering flexibility to move in tight spaces. Their high road speed gets them to the jobsite quickly, and because the articulated frame needs no outriggers, they can be set up and working almost immediately, Terex claims. Features of Terex pick-and-carry cranes include a spa- cious operator's cab, a binnacle-type dashboard, pilot-oper- ated hydraulics and a digital load indicator. Both the hy- draulic oil and fuel tanks have been integrated around the six-cylinder turbocharged and intercooled engine in the rear body, with the latest design in adjustable wear pads and boom structure up front. The center-articulated AT-15-3 model has a lifting capa- city of 15 mt and a maximum boom length of 17.9 m— the four-section boom having two powered sections, the 62 E&MJ; • DECEMBER 2015 www.e-mj.com C R A N E S & R I G G I N G COMPANY PROFILE-PAID ADVERTISEMENT Tsurumi Manufacturing has long been manufacturing, marketing and selling various pumps and related equipment, with a strong focus on submersible pumps. Introduced here are two series of heavy-duty, high-powered slurry pumps equipped with an agitator suited for the harsh conditions of large construction sites, mines, etc. The GPN-series offers motor outputs of 5.5 to 22 kW. The impeller, agitator and suction plate are made of high-chromium cast iron to ensure longer use against wear. And, if the impeller and suc- tion plate wear down to the point of diminishing pump performance, the plate can be replaced or its gap from the impeller adjusted, giv- ing users an easy and inexpensive means for ensuring extended use. The GSD is a new series of heavy-duty, high-powered agitator pumps. Driven by 37 to 75 kW motors, they feature the highest head and volume of Tsurumi's slurry pumps. The impeller, agitator and mouth ring are made of high-chromium cast iron to ensure longer use against wear. Moreover, performance drops due to wear have been minimized by pairing a closed impeller configuration with Tsurumi's unique mechanism that continuously adjusts the clearance between the mouth ring and impeller. Furthermore, pumps are equipped with seal pressure relief ports that release pump pressure applied to the mechanical seal, thus enhancing reliability in extended use. Both of these series come standard with anti-wicking cable entry and inside mechanical seals with silicon carbide faces. Tsurumi prioritizes continuous duty by designing reliable, durable pumps that guarantee stable operation. For more information, contact Tsurumi Manufacturing.
