Manually operated dock levellers
- The construction consists of a moving dock that balances in the upper terminal position with the help of two powerful springs. It locks with a special pedal.
- The operation of the bridge is done manually.
- There is possibility of moving horizontally the construction along the building bay using a guide beam with the help of special pre-stressed pillow-blocks that ensure this horizontal motion.
- The joints of the dock have sufficiently high strength and can withstand loads of over 6 tonnes.
