With over 85 years of engineering experience, Tong has unrivalled experience in designing and building the most gentle, efficient and advanced mobile potato and vegetable grader on the market.
Tong has been manufacturing the market leading Caretaker grading machine since 1980. As they say, some things improve with age, and with our inherent drive to keep our Caretaker at the forefront of crop cleaning and grading technology, our market leading mobile grader really does just keep getting even better!
Designed using the latest technical advancements in inverter drives and user-interfaces, with high levels of efficiency, productivity, and gentle handling in mind, the Caretaker offers efficient handling of a wide variety of crops and is suitable for grading potatoes, onions, carrots, parsnips, beetroot and more. So, whether you’re looking for a mobile potato grader, or you’re grading carrots, onions, beet or bulbs straight from the field, the Caretaker is the complete solution to your mobile vegetable grading needs.
Tong’s market leading EasyClean separator offers truly unmatched crop cleaning performance and control. With Inverter Direct Drive motors on every shaft, the EasyClean has full electric Blue-Inverter technology control with a proven track record of exceptional crop cleaning results. The new Caretaker is fitted with an even more refined, cartridge-style model, the EasyClean II. With a new auto-reject function for removal of foreign objects and the capability to be even more finely tuned, our knowledge and experience allows us to offer the most effective separator on the market with the EasyClean II.
In 2006, Tong introduced a new generation of cleaning separator to the grading market, which revolutionised crop cleaning in all crop and soil conditions, and made the Caretaker the number one selling mobile grader on the market. Over the years we have gained invaluable experience in working with separators like the EasyClean we are proud to offer today. This has given us the knowledge to improve and refine the design and control of the EasyClean separator to provide unparalled cleaning results, ensuring the Caretaker continues to lead the way.
Auto-Touch HMI Control
When specified with an EasyClean separating system, the Caretaker is available with the option of the latest technology HMI touch screen controls. In order to achieve the very best control of crop cleaning in all conditions, touch screen control offers customers a simplified ‘touch of a button’ means of setting the machine to suit different crop cleaning requirements. Users can select crop conditions such as ‘Wet’ or ‘Dry’ and crop type from the display menu, setting the machine to automatically change the speed, position and direction of the cleaning rollers at the touch of a button. This makes setting the separator for different loads exceptionally quick and easy.
And now, Tong’s proven Auto-Touch HMI touch screen control is even more advanced than ever, with the added option of a unique and advanced Pro-Control Interface that facilitates a number of impressive and very useful features. These new Pro-Series features make the HMI control even more user friendly whilst offering enhanced control as well as reduced maintenance and downtime. The new Pro-Series features leave you feeling quite literally empowered at the touch of a button! With advanced diagnostic capabilities including a machine health status report plus fault detection and precise location information on inverter faults and E-Stop alerts, the Pro-Series advancements are leading the way in equipment control.
Blue Inverter Technology
All new Caretaker mobile grading machines are built with Tong’s Blue Inverter Technology, offering the very best energy efficiency, with all electric Inverter Variable Speed Drive, offering energy savings of over 50% when compared to similar machines with standard mechanical drive. When running at full capacity and tested with dry crop conditions, the latest models of the Caretaker run on just 18 amps, offering significant energy savings on previous models.
Heavy Duty Hopper
With heavy duty steel gauge design consisting of chain and lathe construction and heavy duty 4 inch pitch chains with a dual driven shaft, the Caretaker hopper offers the very best quality and reliability, with a total maximum strain of 64 ton. Built with the option of a heavy duty reinforced EP250 rubber chevron belt with vulcanised V cleats or a heavy duty PVC pocket belt, you can be sure that Tong hopper will stand up to demands for years to come.
Trailer Reversing Sensors
Quite literally your hopper loading co-pilot! The Caretaker’s version of parking sensors, make trailer reversing and hopper loading much quicker, safer, easier and more accurate than ever before.
The latest models of the Caretaker are now available with a suite of cameras positioned at different locations around the machine, for easy and instant ‘live’ viewing of multiple areas of the Caretaker from a central location. This allows operators to quickly check the running status of the machine, to check crop flow, blockages, load etc from one viewing screen.
LED Inspection Lighting
For enhanced visibility on the inspection table, the Caretaker is now fitted with energy efficient LED lighting, improving working conditions and picking-off capabilities.
Category 3 Safety System
The foundation of the new Caretaker is built around a computerised Category 3 safety system, for advanced diagnostics and safety settings at the touch of a button.
The introduction of an angle-adjust presentation conveyor in all new Caretaker graders allows easily adjustable feed to any choice of cleaning unit within the Caretaker.
Double Strength Conveyors
All Caretakers are built using the most heavy duty conveyors, with double strength 160B PVG side-tracked belts, ensuring smooth, straight and reliable running that meets the most demanding conditions.
Heavy Duty Canopy
All Caretakers are available with an option of a custom designed and manufactured canopy for full or part coverage of the grader, particularly popular when the machine is to be largely used in an outside location.
RESILIENT PAINT FINISH
Tong has partnered with Internationally-renowned PPG Industries to offer a specialist paint finish on all mild steel painted equipment, giving the Caretaker unrivalled corrosion resistance, excellent durability and outstanding appearance.
The innovative SPECTRACON® coating, which pairs a solvent-based epoxy primer with a high-performance finish layer, not only ensures surface durability; the resilient undercoat offers superior anti-corrosion protection should the top finished coating suffer chipping or damage, giving an additional layer to prevent rust, oxidation or steel tarnishing. The eco-friendly acrylic polyurethane paint has been designed with challenging exterior conditions in mind, and can also withstand direct sunlight, preventing appearance fade and ensuring a long-lasting glossy appearance. Tong’s specialist painted finish can be supplied in any colour, to match existing machinery, surroundings or site requirements.
Energy Efficient50% Less
The new Caretaker is exceptionally energy efficient, running on as little as just 18 amps*, an energy saving of over 50% (*dependent on crop and condition).
