SIPMA OS 7531 MAJA bale wrapper is fully automated selfloading machine, attached to the tractor. Full automation of the process is provided by an advanced control system which allows pre-programming a wrapping cycle.
- „Front-back” technological system allows work in the same direction as press works. Such solution ensure fast bale loading and foil-wrapping during ride to the next bale. Coupling with press, ensuring simultaneously baling and wrapping during one ride.
- Universal foil film feeder (SIPMA OS 7530 MAJA and SIPMA OS 7531 MAJA) allows the use of 0.50 and 0.75 m wide films.
- Aluminium milled foil film feeder rollers ensure the initial foil stretching, tightness and proper adhesion during the wrapping process.
- Bale elevator allows for putting bales on their bottom or rolling them on their side surface into the field and also protects the wrapped bale from possible damage during unloading.
- Wide tyres provide the opportunity to work on wetlands and peat fields.
- Hydraulic film catcher-cutter works automatically after each bale wrapping process. It provides a considerable acceleration of the wrapping process and its efficiency.
- Adjustable drawbar the working and transport position enables efficient collection of bales. It also facilitates moving the machine and its transport on access roads (including public roads) to the field.
- Autonomous hydraulic power system (additional equipment):
- separates the hydraulic system of the wrapper from the hydraulic system of the cooperating tractor;
- ensures constant and optimal demand of oil supplying the hydraulic block of the wrapper;
- maintains a constant level of oil purity in the system.
- Functions of the electronic controller:
- manual or fully automatic operation of the wrapper;
- graphic visualization of current wrapping process;
- counting the number of wrapped bales;
- programming the number of foil layers (depending on the kind of film used), when reached, the machine passages automatically to next work stage;
- displaying the status of sensors (evaluation of efficiency or inefficiency of their operation) allows to replace damaged sensor, without the need to call the service;
- displaying the sum of wrapped bales since the installation of the electronic control on the wrapper;
- automatic machine setting for work and transport;
- number of table revolutions can be corrected without interrupting the wrapping process;
- possibility of pausing the automatic table wrapping mode and resuming it at the storage location;
- foreign language support.
