1. Applicable to large interval between gate blocks, saving cost of civil construction.
2. Generally it takes the Gate less than 2min to raise or to lower, while it usually
takes the rubber dam 2-3h to finish the same operations.
3. Commonly the service life of the product can reach 50-60 years; while it is easier
for the rubber dam to get aged, especially in northern regions it is easier for ice
blocks to tear the rubber dam in chill winter.
4. Compared with the rubber dam, operation of the Gate can be done more
automatically.
5. Machine lock is adopted to make it locked at any angles when the dam is raised or
lowered, or when water level is adjusted. While it is necessary for the rubber dam
to charge air to keep the function of the dam normally,
6. Save resource. For a steel dam of 100m long, only four driving device is needed,
and the power is 60kW per hour, and the operation time is 2-3min only; while for
rubber dam of the same length, the power climbs to 100 kW per hour, and operation
time increases to 2-3 hours.
