New Stone Slinger keeps operators out of the truck and on the job

Remote-operated Creep Drive allows operators to control the Stone Slinger and maneuver the truck from outside the cab

W.K. Dahms Mfg. Ltd. has successfully launched a new generation of remote controls for Stone Slinger truck conveyors that can dramatically reduce the time to unload and place aggregate loads with precision.

The new Stone Slinger Creep Drive system provides operators with a remote control feature that not only controls the speed and direction of the conveyor, but allows the operator to remotely maneuver the truck itself around the jobsite. The operator now has a single set of controls to run the conveyor and reposition the truck for ideal placement of the material, without returning to the truck. The truck and the Stone Slinger become a fully integrated material delivery system.

Scott Nelson, Manager of W.K. Dahms, reports that the first of the new Stone Slingers equipped with Creep Drive was delivered at the end of August to John Da Silva of Rock Concrete Forming Ltd. in Mississauga, Ontario. After putting the Stone Slinger through its paces for a full season, Da Silva says, “If I was buying another truck, I wouldn’t get anything else – no question.”

According to Da Silva, his investment in the Creep Drive feature has paid off well. “On a typical weeping tile job, the driver has to go back and forth to move the truck four or five times. And, each time, when you get into the truck, you have to turn the PTO off, drive the truck, put the air brakes on again and restart the PTO. It’s the time-saving that pays you back.”

The right place to be
By using the remote control to move the truck, the operator remains outside the cab to keep the material flowing until the load is completely delivered. Da Silva says that getting out of the truck is the right place for operators to be. “You get out here and you can see everything. We are always working in very tight spaces. You can watch the wheels and the ground more closely than if you’re steering from the cab. You won’t ever put the truck into a pothole or a ditch, so you never have to wait for another truck to come and pull you out.”

The Stone Slinger Creep Drive adds a complete hydrostatic drive system to the standard powertrain of the truck. A hydraulic driven gearbox is inserted into the driveline. A CAN Bus panel controls all hydraulic and operating functions and communicates with the remote, which the operator carries in a sling.

Jobsite safety designed in
Nelson explains that safety was a key factor in Dahms’ design of the system. “The maximum speed the truck can achieve under hydraulic power is 2.5 km/h – a comfortable walking speed. The control circuitry receives constant feedback on the actual wheel speed from the truck. If the truck’s on an incline, the hydraulics will brake its speed automatically. Several fail-safes are built in as well. If the wheel speed exceeds 4 km/h, the CAN Bus will shut down and stop the truck completely.”

Lower costs, better results
Da Silva finds that the Creep Drive leads to better job quality, too, with less wasted material. Operators naturally tend to avoid extra walks back to the truck if they possibly can. By making it easy to move the truck into the best location, Creep Drive helps operators to distribute the material more precisely and consistently with no extra time or inconvenience. For a contractor like Da Silva, that translates into lower costs for clean-up and for material.

Revolutionary Concrete Mixer

On the desks, computer keyboards are buried under black and white and colour sketches. Others, hanging in order on the walls, are constantly looked at in search for new ideas, while on always turned on monitors 3D models are displayed. This time we are in the fascinating dimension of the Styling Centre of Cifa in Senago, where design of Coguaro took shape, the new and gutsy mixer for transporting concrete in demanding environments.

After a year from assignment of the Red Dot Award (world level award for Product Design) to the Energy a truck mixer, a few days ago the 2015 award was assigned to this “feline with 4…wheels”. “The jury, explains Samuele Montorfano, responsible for the Styling Centre Team, awarded the experience proved by Cifa in managing the planning and design parts, and in caring for product details”.

Volvo's New Highly Responsive EC220E Excavator

The 22-ton Volvo EC220E is the newest excavator from Volvo Construction Equipment and is fitted with a top-range Tier 4 Final Volvo D6 engine that meets strict emissions legislation across North America without compromising on power. The fully optimized hydraulics system and ECO mode deliver the precise amount of power required to complete the task in hand, while the auto engine shutdown feature helps further reduce fuel consumption and emissions by switching off after the excavator has been inactive for a pre-set amount of time.

The increased pump input power on the Volvo EC220E enables highly responsive operation for greater productivity and cycle times — and with the boom float function, the pump power normally used for boom lowering can be saved or used for other functions, also reducing cycle times. The new valve controls the boom operation proportionally according to the arm operation while grading. This system also improves lifting controllability while traveling simultaneously. When grading, the operator is now capable of maintaining the bucket teeth parallel to the ground even in H mode during the entire cycle. Fuel efficiency has been improved from previous model by 5 percent.
