■Electrical motor is of non-under-oil structure,F grade insulation,
good heat enderance and long life.
■Both electrical motor shaft and thruster are hard chrome plated on the surface making life of sealing parts greatly prolonged.
■Balancing air house is arranged at one side of oil cylinder casing. Thruster can be installed at any direction within range of 0~180 °, thus enlarging its scope of usage.
■All sealing parts and bearing are of world known products.The sealing is reliable and performance life is long.
All thrusters can realize some additional functions after equipped with additional devices.
●Up limit switch can indicate such information as whether brake is open, whether the thruster is in theright position.
●Down limit switch can indicate whether the brake is properly close,whether the thruster return to right position. Upper and lower limit switchs can be arranged simultaneously.
●Add built-in brake spring or release spring (only for short stroke thruster), release spring can be decided by customers, but the force of built-in spring can not be exceeded (see parameter tables).
●Delay valve of lift and delay valve of fall or delay of lift/fall valves can infinitely delay lift and fall. Delay range is from rated action time to 30 seconds. Specific delay can be set as per customer's requirement.
