They indeed allow to secure the load by simply operating a hydraulic function to lift them. They are then held into position by check valves. Human intervention is in this way limited. The use of straps and their regular tightening check are therefore no longer necessary.
The side ladders can be lowered on both sides. You can in this way load on the left or right side, as you want.
These hydraulic ladders are specially designed for use with bales with the most common dimensions: a double row of 3 piled up square bales of 90 cm high, 4 piled up square bales of 70 cm and 2 or 3 round bales with a diameter from 120 cm to 200 cm.
The main structure is made of round tubes to avoid damaging the bales.
Advantages:
- securing the whole load, both for the driver and during transportation;
- significant time saving when loading and unloading while limiting and making the human intervention easier by only activating the tractor distributor to lift or lower the side ladders (no need to use straps or control their tightening);
- versatility since all bales with common dimensions can be used.
