Eldro thruster

Types of ELDRO Thruster

The Eldro thruster is a powerful tool in the world of logistics, transportation, and material handling, and it is developed by Schneider Electric. Eldro thrusters are used in cranes, lifts, hoists, and other overhead handling equipment to provide reliable and accurate control of load movements. The Eldro thruster controls the electromagnetic brake of the motor. When the thrust is applied to the brake, it slows down the load, and when pressure is released, the load can be moved, and the braking is fully applied. There are different types of Eldro thrusters, and they include:

• ELDRO D:

  The Eldro D thruster is a simple and straightforward brake control. It applies and releases brake control with a direct mechanical connection. The control circuit is open when the brake is applied, and it is closed when the brake must be released. This type of Eldro brake control is widely used in applications where simple and reliable control is required, such as in cranes and lifts.

• ELDRO F:

  The Eldro F is a brake control with a fail-safe function. In case of a power failure, the brake is automatically applied to stop the load movement. This makes the Eldro F suitable for applications in which safety is paramount, such as in emergency situations or in dealing with hazardous materials. The fail-safe function is achieved through a spring mechanism that applies the brake when there is no power supply.

• ELDRO C:

  The Eldro C is a complex brake control with a control and monitoring system. It allows for precise control of brake application and release, as well as monitoring of brake status. This makes the Eldro C suitable for applications that require high precision and reliability, such as in high-speed cranes or in processes where precise positioning is essential. The control and monitoring system can be integrated with other control systems for synchronized operation.

• ELDRO H:

  The Eldro H is a hybrid brake control that combines electrical and electronic control with mechanical actuation. This allows for remote control of brake application and release, as well as integration with other control systems. The Eldro H is suitable for applications where remote control and automation are required, such as in automated material handling systems or in lifts with multiple landing points. The hybrid design ensures reliable and accurate brake control under various operating conditions.

  The casing, cover, and thrust block of the Eldro thruster are all constructed of cast iron. The electrical motor is enclosed in a cast iron housing. The electrical motor also has a thrust bearing, which minimizes the axial load on the motor.

  The propeller and other hydraulic components of the thruster are made from bronze. The Eldro thruster also utilizes a set of cast iron construction valves, piping, and fittings.

• Power supply:

  Eldro Thrusters are available in voltage options of 400, 440, 480, 660, and 690. The frequency option is 50/60 Hz.

• Motor design:

  The motors used in Eldro thrusters come with IP54 and IP68 ratings. The thrust generated by the thruster ranges between 30 to 2500 kN. The motor power of the thruster ranges between 10 to 2000 kW. These motors are also designed with cooling systems such as IC 07, IC 41W, or IC 61W.

• Propeller design:

  The propellers used in Eldro thrusters have a diameter range of 180 to 1,800 mm. The number of blades on the propeller ranges from 3 to 5. These propellers are also designed with soft, hard, or hybrid blade configurations.

Below are some general maintenance tips for the Eldro thruster:

• Seal inspection and replacement: The seals used in Eldro thrusters should be inspected regularly for any signs of wear and damage. Any damaged seals should be replaced immediately to prevent leakage.
• Bearing inspection and lubrication: The bearings of the Eldro thruster should be inspected regularly to ensure they are in good condition. These bearings should be lubricated to reduce friction and wear and tear during operation.
• Electrical system inspection: The electrical system of the Eldro thruster should be inspected regularly to ensure it is working properly. Loose connections and damaged cables should be tightened or replaced to prevent electrical failures.
• Cleaning: The Eldro thruster should be kept clean by removing any debris, marine growth, and sediment buildup. This can be done by washing or inspecting the thruster regularly.
• Regular inspection: The Eldro thruster should be inspected regularly before and after use. Any signs of wear, damage, or abnormalities should be addressed immediately to prevent further damage.

How to Choose ELDRO Thruster

Choosing the right ELDRO thruster for a specific application involves considering several factors to ensure optimal performance and reliability. Here are some tips to select the right Eldro Thruster:
