Detailed Technical Data Sheet for Used Overhead Crane

1. General Overview

The overhead crane used for steel warehouses is designed to move heavy loads in industrial environments. This model is equipped with a double hook and has design specifications aimed at ensuring safe and efficient operation in the steel sector.

2. Technical Specifications

• Type : Double hook overhead crane
• Capacity per hook : 4 tons
• Maximum combined capacity : 8 tons
• Gauge (Distance between rails) : Approximately 16 metres
• Year of construction: 2004
• Weighing system : Load cells for real-time weight monitoring

3. Main Components

1. Load-bearing Structure : Made up of main and secondary beams, designed to support the weight of the load and distribute the forces evenly. Usually made of high-strength structural steel.

2. Hooks and Trolleys : Equipped with two hooks, each with a capacity of 4 tons. The hooks are mounted on trolleys that move along the main beam of the overhead crane.

3. Motors and Gearboxes : Motors are responsible for movement along the rails and vertical movement. The reducers allow you to adjust the speed and the force applied.

4. Command System : Includes control panels and user interfaces to manage the movements of the overhead crane and monitor operational data, including weights thanks to the load cells.

5. Load Cells : Integrated sensors to measure the weight of the lifted load and transmit the data to the control system.

6. Rails and Tracks : Support structures that allow the movement of the overhead crane along the warehouse.

4. Mechanical Characteristics

• Movement : The overhead crane moves horizontally along the rails and vertically by lifting the hooks.
• Lifting and Movement Speed : Variable, adjustable according to operational needs.
• Braking System : Includes electromagnetic or disc brakes to ensure safe stopping.

5. Calculations and Optimal Use Parameters

To ensure optimal use of the overhead crane, it is essential to consider:

• Lifting Capacity : The maximum capacity of 8 tons must be well distributed to avoid overloads. The formula to calculate the distributed load is:

  $$C$$

  Where CC $C$ is the load capacity per hook, FF $F$ is the total load, and nn $n$ is the number of hooks in use.

• Load Balancing : Make sure the load is balanced to avoid excessive stress on the hooks and structural components.

6. Workable Materials

The overhead crane is designed to handle heavy materials typical of the steel sector, such as:

• Steel rods
• Steel sheets
• Steel tubes and profiles
• Scrap metal

7. Maintenance and Control

1. Regular Inspections : Check the frame, hooks, and trolleys for signs of wear or damage. Check load cells for accuracy.

2. Lubrication : Keep moving mechanisms well lubricated to prevent wear and ensure smooth operation.

3. Control System Verification : Make sure the control system and load cells are functioning properly and providing accurate readings.

4. Brakes and Safety : Check and test your brakes regularly to ensure they are working properly and providing a safe stop.

8. Evaluation of a Used Overhead Crane

• Structural Conditions : Check the state of the supporting structure and main components. Look for signs of corrosion, cracks, or structural damage.

• Operation of Mechanisms : Make sure that motors, gearboxes, and hooks operate smoothly and efficiently.

• Maintenance Records : Check maintenance records to ensure the overhead crane has been maintained regularly.

9. Sectors of Use

This type of overhead crane is ideal for:

• Steel Industry : For moving and positioning steel and heavy materials.
• Industrial Sectors : Where high lifting capacities and heavy handling operations are required.
• Warehouses and Workshops : Which handle large volumes of heavy materials and require a high load capacity.

10. Advantages of Buying Used

• Lower Cost : Buying a used overhead crane is generally less expensive than buying a new one.
• Immediate Availability : Often available immediately for use.
• Minor Depreciation : Used equipment has already suffered significant initial depreciation.

Make sure you buy from a reputable dealer and do all the necessary checks before purchasing to ensure the overhead crane meets your needs and works properly.
