Laura Gate, wired drum type and rack type.

This is a roller gate that supports the water pressure load on the gate body with rollers, reducing resistance during opening and closing. 【Features】 ○ The opening and closing of the gate body is done by lifting it from both ends with wire ropes and winding it with a winch. ○ A manual operation device is installed to allow for manual control of the opening and closing mechanism. ○ The brake system is equipped with an electromagnetic brake directly connected to the motor and a hydraulic lift-type mu-lift brake. ○ A high-torque motor designed for sluice gates is used, along with a silo-type reduction gear. ○ The structure of the gate body is designed to be safe against water pressure loads, and the upper or lower structure of the gate body is carefully considered to prevent vibrations caused by water flow. ○ A design that uses valve control is also available to simplify the structure of the motor and reduction gear of the opening and closing mechanism.
