EquipmentWorld.com | June 2015 19 contractor of the year | by Marcia Gruver Doyle | MGruver@randallreilly.com EquipmentWorld.com | June 2015 19 marketplace | by Equipment World staff This month, we're concentrating on the machine introductions coming out of Intermat, which took place April 20-25 in Paris, France VOLVO Volvo Construction Equipment used Intermat for the global introduction of its 113,410-pound EC380EHR and 141,140-pound EC480EHR high-reach demolition excavators. The excava- tors use a frame-mounted Falling Object Guard and safety windows to met demolition demands. Also on board are rear and side mounted cameras to give additional visibility. A micro-mesh screen on both the doors and engine cowl keeps out particles, and full-length track chain guards prevent sharp objects from lodging on the tracks. Providing additional protection is a guard that protects the swing ring bearing seal and grease piping from damage. De- molition's dusty, dirty environment is addressed with Volvo's dust suppres- sion system, which has a hydraulic lifting pump, eliminating the need for a separate solution. Four nozzles, two on each side of the arm, emit a fine mist that traps dust. The cab tilt function is controlled by pressing buttons located on the joysticks, al- lowing operators to adjust the tilt up to a maximum of 30 degrees without taking their hands off the controls. In addition to the cameras mounted on the rear and the sides, there are two cameras mounted on the arm. Each camera angle can be viewed on an 8-inch monitor inside the cab. ALLIANCE TIRE The 506 Dual Master excavator tire from Alliance Tire Group looks almost like a dually. There are two distinct, mirror-image tread patterns until you look close. It's actually one contiguous tire, and one air chamber across the width of the tire, but it has a rubber web spanning a low spot in the middle that links the two pieces. This all-steel radial design comes in a 315/80R22.5 size and two tread patterns: on/off road or pattern 528 for moderate traction. The continuous ring of rubber gives you the floatation of a dually but means you'll never get anything stuck between them or need to install a rubber ring between two tires to keep debris out.
