Properly Sized Wheel Drives – Optimizes Oxbo Harvester

Kraft Works with Oerlikon Fairfield to Recommend Robust Torque Hub Drive Solution for New Corn Harvester

An early prototype drive package for the Oxbo 8840 Corn Harvester faced problems during the research and development phase prior to product launch. All equipment from Oxbo undergoes rigorous testing prior to release.

Challenge

The initial equipment tested for the Oxbo 8840 corn harvester experienced longevity and fatigue failures during initial validation protocols A more robust system was required for proper functionality and longer system life. Oxbo called on the experts at Kraft Fluid Systems to help them specify a more durable solution.

Solution

Kraft brought a solution to Oxbo using Oerlikon Fairfield Torque Hub wheel drives. After thorough assessment of needs, machine requirements, specifications, and features, Kraft proposed a properly sized and rated CO series solution for the four-wheel drive harvester. Kraft sales and application personnel worked closely with Oxbo designers and Fairfield’s application engineering department for the approved solution. Kraft and Fairfield provided evaluation support during prototype testing, and multiple inspections and analysis were performed on units at various stages of the prolonged testing.

Results

Properly sized Torque Hub CO drive components specified in the Oxbo 8840 Corn Harvester resulted in optimal equipment performance and product life during testing. Testing was based on the duty cycle of the machine which resulted in better performance and longer life of the drive system.

Mechanical Automation – Vogel Engineering

Saving Time and Reducing Labor Costs During Harvesting

Vogel Engineering, a manufacturer of specialty agricultural and harvesting machinery, was tasked by a customer to develop machinery to improve harvesting results for squash, pumpkins and gourds with a machine that required less labor and delivered “hand-picked quality” results.

Challenge

To create a mechanical solution to pick up the vegetables with care, while handling industry standard pallet crates quickly and efficiently.

Solution

Kraft automated the handling of the pallet containers allowing for faster cycle times with exact placement of the crates as the machine filled them, unloading the full crates to the ground where they were picked up by multiple forklifts, and keeping the picking mechanism flowing constantly by minimizing the downtime between changes when a new pallet needed to be put in place.

Kraft’s Plus+1 programmed microcontroller used a combination of operator inputs and proximity sensors to accurately complete the cycle in minimum time allowing crews to harvest more productively than hand picking alone. The PVG 16 proportional valve controlling the pallet mover system was automated by the controller with the option to manually control when needed using Danfoss JS120 joysticks.

The machine is propelled by a (Kraft supplied) Danfoss Series 90 pump driving Danfoss H1 variable displacement bent axis motors. The final drives are Fairfield W16 Torque Hubs. Work functions are powered by Danfoss Series 45 variable displacement pumps with pressure compensating and load sensing controls.

Results

Vogel’s customer saved time, reduced labor costs and resources with a fully automated system while being able to safely harvest much more productively than hand picking alone.

“Our client harvested 1,000 boxes of squash per day with a crew of 8, rather than 1 box per man-hour with traditional hand-picking method,” said Wayne Vogel. “They were quite happy with the results.”

 

 


Grout Pump – EZG Manufacturing

Efficiency meets easy operation on the job site.

When it comes to grout pumping, having the right equipment can make the job easier and more efficient. Unsatisfied with inferior commercial pumpers, EZ Grout decided to create their own pump to get the job done better and faster with less manpower. As a result, the Hog Pumper was born.

Challenge

A masonry customer was looking for a more efficient way to fill block walls with grout. They were using a dated pumping system with a pressure compensated pump, on/off directional valves, and mechanical switching. Flow was not variable and the pump operated with strong pulsation. Two people were required to safely operate the equipment.

Solution

Kraft Fluid Systems developed a high performance system utilizing a Danfoss variable displacement Series 45 pump with load-sensing control, Danfoss PVG proportional directional valves, custom cylinders with linear position sensors, Danfoss CAN based Plus+1 microcontroller, Danfoss Plus+1 programmable display and HBC-radiomatic wireless controls.

Results

The value-added system now delivers stability even at low flow rates. This improved performance makes holding the concrete discharge hose effortless. Smooth operation and wireless control let a single operator manage a job. The max output flow is now higher strengthening the competitive position in the market. The new display shows how much material has been pumped enabling accurate invoicing. A diagnostics page programmed in the display improves troubleshooting and offers access to service tools without connecting a computer.
