July 2009 – RollOuts
Volvo Construction Equipment North America, Inc. says its new EW230C wheeled excavator is engineered to provide stability for handling bigger loads. Its design ensures that the rear axle weight, when fitted with the standard counterweight, is below 12 tons; a heavier counterweight is available for applications not requiring the machine to be moved on the road. With the light counterweight, the machine weighs 21.6 to 24.3 tons, depending on machine configuration (23.1 to 25.6 tons with the heavier counterweight).
The excavator is powered by a Volvo D6E EHE3 diesel engine. Additional features include:
- Access to the superstructure via steps for easy servicing and maintenance checks;
- New and higher-capacity cooling module;
- Load-sensing hydraulic system that features two pumps — one for the attachment and travel, and a second, closed-loop slew pump;
- Larger hydraulic cylinders; and
- Digging forces 10 to 15 percent greater than on the EW210C.
In addition, 95 percent of the machine is recyclable, according to the company, making it environmentally friendly.
Discharge conveyor unloads trucks quickly
Superior Industries added a new 48-foot folding discharge conveyor to its line of RazerTail truck unloaders. According to the company, the conveyor is designed to move material from belly- or end-dump trucks in minutes. Discharge heights adjust hydraulically between 8 and 12 feet, giving users the flexibility to hit higher feed points and eliminating the need for transfer conveyors between the truck unloader and larger radial stacking conveyors. An electrical panel with main breakers and starters allows push-button operation of the hoppers, control pump, and drive motors.
