Kobelco Construction Machinery USA, Houston, has announced the availability of its new SK210D multidismantling machine in North America. Kobelco notes that many contractors received a sneak peak at this machine during ConExpo 2014 in Las Vegas earlier this year. Kobelco showcased the machine dismantling an automobile.

Kobelco has manufactured more than 1,000 of the machines in Japan since 1979.

Kobelco notes that machines like the SK210D are multifaceted when it comes to dismantling complex equipment that requires delicate handling, such as automobiles, where environmental laws require that steps be taken to contain oils and other contaminates that may be harmful to the environment. The speed and accuracy of dismantling automobiles with the SK210D is increased tenfold over hand dismantling, savings owners substantially on labor costs and minimizing the risk of fines, Kobelco says.

The SK210 is the first of Kobelco’s demolition machines available in North America. It is designed to take apart vehicle bodies, engines and other metal components with precise, safe and efficient operation.

The equipment has two specialized crushers that allow for different dismantling tasks:

• a multidismantling crusher is suited for small-scale separating and the sorting of all types of metal products, including small parts such as electrical fittings and harnesses; and
• an optional vehicle-dismantling crusher offers a powerful grab, increased cutting force and rotational torque powerful enough to cut through a chassis and frame, the company says.

The Kobelco Innovation Clamp Arm features a bowl-shaped grip and powerful cutting teeth with different shapes on the right and left sides to enable efficient bending, breaking and tearing, the company says. 

The advanced features highlight Kobelco’s dedication to providing equipment that functions efficiently and safely in real-world worksite situations and conditions, according to Kobelco.

Robert Harvey, who help found the recycling and waste management firm E.L. Harvey & Sons, Westborough, Massachusetts, in 2011, passed away on Aug. 30, 2014.

Robert Harvey joined his father Emory L. Harvey, and his brother, James A. Harvey, in the family business E.L. Harvey, which was formed in 1911. In 1940 the company began offering recycling services.

He was president of the company until his retirement in 2004.

Harvey is survived by his wife of 72 years, Jane; two sons, William and Ben; and a daughter, Dorothy Thompson. His eldest son, Robert Jr., died in 1984.

Family owned for four generations, E.L. Harvey operates a high-grade scrap paper processing and baling plant that also contains a plant-based shredding system. The company also operates a waste transfer station containing a backup baler for handling all recyclable materials and wastes.

Additionally, the company operates a C&D transfer and recycling operation.

DX300LC-5

DX350LC-5

Doosan, based in West Fargo, North Dakota, has introduced two new Tier 4-compliant Doosan excavators in the United States and Canada — the DX300LC-5 and DX350LC-5. The excavators feature improvements in fuel efficiency, productivity and durability, Doosan says, and replace the DX300LC-3 and DX350LC-3 models respectively.

The new Doosan crawler excavators have engine modifications and after-treatment technologies to meet Tier 4 emissions regulations, the company says.

Doosan’s 271-horsepower DX300LC-5 and 318-horsepower DX350LC-5 excavators are powered by Scania diesel engines that have been configured with a high-pressure common-rail (HPCR) fuel delivery system as well as cooled exhaust gas recirculation (CEGR).

The new excavators combine selective catalyst reduction (SCR) with a diesel oxidation catalyst (DOC) to reduce engine emission levels, according to Doosan.

Available for the DX350LC-5, D-ECOPOWER optimizes hydraulic system output with engine horsepower, improving machine efficiency, productivity and fuel consumption, as well as refining machine control and enhancing operator comfort. A pressure controlled pump, closed center main control valve and various sensors in the excavator are designed to electronically detect and control the precise amount of hydraulic oil required to perform a task.

Similar to previous Doosan excavators, operators can choose from four power modes for more control to better balance fuel consumption and machine power to the working conditions. Power modes include the following:
 

• Power+ mode: delivers the fastest workgroup speeds for loading trucks, top digging performance and extra power for digging in hard ground
• Power mode: provides exceptional power and performance for tough digging conditions and truck loading tasks
• Standard power mode: balances the excavator’s fuel consumption in everyday digging, grading and lifting tasks
• Economy mode: reduces fuel consumption for low-demand applications, slows down machine movement for conditions that require extra precision

To further match Doosan excavators to the application at hand, operators also can choose from four work modes — digging, breaker, shear and lifting — to maximize efficiency and fuel economy in specific applications.

The new Tier 4 compliant Doosan excavators feature improved fuel efficiency to help owners reduce operating costs. The company says that its Tier 4-compliant DX350LC-5 excavator has a 10 percent fuel savings from the equivalent Tier 3 model, for example. For further fuel savings, auto shutdown helps owners save fuel during non-working conditions.

The excavators also feature an improved 7-inch LCD display panel and the following updates:

• improved serviceability for uptime protection;
• auto belt tensioner: fan and air conditioning;
• anti-skid plates for better traction on steps and other walking surfaces;
• enhanced access to the emergency engine stop;
• battery and alternator upgrades to minimize downtime;
• for greater operator comfort, the floor pedal angle has been improved by 10 degrees.

a number of factory-installed options are available, including:

• additional work lamps;
• cab guarding for special applications;
• diesel-powered coolant heater for cold starts;
• rotate circuit hydraulic piping;
• straight travel pedal, which allows the operator to travel in a straight line more easily; and
• two-way auxiliary hydraulic pedal (in addition to joystick control)

Doosan DX300LC-5 and DX350LC-5 crawler excavators come with a standard three-year subscription to telematics, commonly known as “machine intelligence.” Telematics allows equipment owners to monitor machine location, hours, fuel usage, engine idle versus work time, error codes, and engine and hydraulic temperatures. Owners and fleet managers can monitor their machines remotely after they log in to a website account. Equipment dealers can also help customers through telematics by responding to machine warning messages, providing the proper parts and service after reviewing the website and diagnosing an issue with a machine, and then sending a field service vehicle to make the repairs.
