CAN in a landfill compactor and shredder

Source: CAN Newsletter June 2010

Tana’s Shark 440DT on tracks is a hydraulic driven, diesel engine powered, single shaft, low speed mobile shredder. Its diesel engine and hydrostatic transmission are controlled by a CAN-based control system from Epec. It also helps to protect the machine from overloading, overheating and damage caused by non-crushable material. Tracks ensure good on site mobility in challenging conditions. The machine is suitable for the shredding of most reusable, recyclable and recoverable materials. The purpose may be volume reduction, renewable energy fuel production or recyclable material production. It is able to handle materials from domestic waste to waste wood, from plastics to cardboard and it can be used either as pre-shredder or making the required particle size in one phase. The Tana Gx Series landfill compactors range from 26 to 52 tons featuring  full-width front and rear drums with a large number of wear-resistant steel crushing teeth that penetrate every fresh layer thus minimizing the number of compaction passes. The dozer blade construction enables accurate cutting and breaking of the load giving improved control over the spreading work. The Epec system controls and monitors almost all functions on the landfill compactor. The features of the machine can be changed by updating the application program. Through the CAN-based Epec 2040 color display remote management, alarm and service logging, diagnostics and monitoring functions are also featured on the display. The Epec 2024 unit controls the engine, hydraulic drive, gearboxes, brakes, steering, dozer blade and bucket as well as the sensor diagnostics. The Epec 2038 mini control unit controls buttons, joystick and sensor diagnostics. Epec 2040 display also loads and manages the parameters of the program. The electronic engine (power train) management system of the landfill compactors is connected to the Tana computer diagnostics system. The Pro Track remote management system allows to reach the machine’s control system via Internet through a wireless connection e.g. for immediate trouble-shooting. The system also automatically produces operation reports.
