Electro-hydraulic Thruster With Return Spring

  We are a factory to produce electro-hydraulic durm brakes, pneumatic drum brakes, electro magnetic drum brake, electro hydraulic disc brakes, air disc brakes, safety brakes etc. Choose from both fail-safe and active braking systems to meet the needs of your specific application.  Whether you need stopping, holding, e-stopping or tensioning, Hindon can accommodate your industrial disc brake needs.  For example, our brakes are used for main hoists, boom hoists, bridge crane drives as well as trolley travel drives.  In addition, they are used in various types of winches for mining, construction, drilling rigs, elevators and stage, speaker or scoreboard systems.  Other examples are uphill, downhill and overland conveyor applications.  We also have extensive references in steel mill rolling and coiler applications

1. Main Feature：

• The casing is made by casting aluminum alloy ,light and good-look.

• Electrical motor is of non-under-oil structure,B grade or F grade insulation (according to customer's requirements)durable and good heat resistance.

• Cover of junction box is tightly sealed.Cable stuffing box is adopted for inner wire,which is firm and reliable.Electrical protection of casing reaches IP55 grade.

• The surface of motor axle and pusher is handled specially to mark the sealing parts much more durable.

• Balancing air house is set at one side of oil cylinder casing which can make the thruster to be installed at any direction within rang of 0-180 degree and enlarge the using range.

• All sealing parts and bearing of Ed series are all world famous products.The sealing is reliable and durable.

• Fastening parts of Ed series are made of stainless steel,good-look and durable.

 2. Additional Option

• Up limit switch,which can indicate whether brake is open,or whether the thruster is at the right position.

• Down limit switch,which can indicate whether the brake is properly close,whether the thruster return to right position.Up and down limit switches can be set together.

• Build-in spring or release spring only for short thruster)Spring force can be decided by customers,but within the force limit of built-in spring (refer to parameter tables).

• Heater Customers can require heaters in the place where ambient temperature is below -25°c,Parameters of heater are attached (refer to Tab.1)

• Up delay valve,down delay valve,Up/down delay valve,can prolong the lifting and falling time without limit,delay range from rated action time to 30 second,specific delay valve can be set as customers' requirements.
