I'm selling two used Omis overhead cranes. The overhead cranes are double-girder and have a low-profile hoist trolley. This allows the used overhead crane to be used on extremely low warehouse heights. If you have very low space between the runways and the ceiling, this is the used overhead crane for you. It only takes up 680 mm between the rails and the ceiling. One overhead crane has a gauge of 18.5 m, the other 18.7 m. They are currently not working, although they undergo periodic inspections. They are equipped with a Donati double-speed hoist. They are like new. ### Operating Principle of a 20-ton OMIS DOUBLE-GIRDER Overhead Crane An overhead crane is a type of industrial crane mounted on rails above a work area. The 20-ton OMIS DOUBLE-GIRDER model is designed to lift and move heavy loads within a defined area, such as a warehouse, factory, or workshop. The operating principle of an overhead crane includes the following components and stages: **1. Crane Structure:** - **I Beam:** The main beam is mounted on rails installed at a certain height above the work area. This beam supports the trolley and the lifting system. - **Trolley:** The trolley slides along the beam and can move horizontally to position the load above the desired work area. - **Hook or Lifting Bucket:** The hook or lifting bucket is used to grasp and lift the load. It is connected to the lifting mechanism via a chain or cable. **2. Movements:** - **Longitudinal Movement:** The overhead crane beam moves along the rails, allowing it to cover the entire work area. - **Transverse Movement:** The trolley moves horizontally along the beam, allowing the load to be moved from one side to the other. - **Vertical Movement:** The lifting mechanism, usually a winch or electric motor, raises and lowers the load. **3. Control:** - **Control Panel:** The overhead crane is equipped with a control panel that allows the operator to manage the movements of the carriage, trolley, and hook. This may be a remote or on-board control, depending on the design. **4. Safety:** - **Protection Systems:** Overhead cranes are equipped with safety systems such as overload sensors, automatic brakes, and height limiters to ensure proper operation and prevent accidents. ### How to Use 1. **Preliminary Inspection:** Before use, perform a complete check of the overhead crane to ensure that all parts are in good working order and that there are no signs of wear or damage. 2. **Load Positioning:** Load the load onto the hook or lifting bucket. Ensure that the load is well balanced and secure. 3. **Movement Control:** - **Longitudinal Movement:** Use the control to slide the beam along the rails to position the load over the desired area. - **Transverse Movement:** Move the trolley along the beam to position the load in the exact location. - **Vertical Movement:** Raise or lower the load using the lifting mechanism. 4. **Precision Maneuvers:** Use the control carefully to move the load and position it precisely. 5. **Inspection and Maintenance:** Perform regular inspections and preventative maintenance to ensure that the overhead crane operates safely and reliably. ### When to Buy a 20 Ton OMIS DOUBLE GIRDER OVERHEAD CRANE 1. **Heavy Load Handling:** If your business needs to lift and move heavy loads, such as building materials, heavy equipment, or large industrial components, a 20-ton overhead crane is essential. 2. **Large Workspaces:** If you work in an industrial or warehouse environment with large spaces and need equipment that can cover large areas, an overhead crane is the ideal solution thanks to its ability to move along rails. 3. **Efficiency and Safety:** An overhead crane increases operational efficiency and improves safety, reducing the need for manual lifting and minimizing the risk of injury. ### Why Buying a Used Overhead Crane Is Worth It 1. **Economic Savings:** Buying a used overhead crane is often much cheaper than buying a new one. This is especially advantageous if you have a limited budget but need reliable, high-capacity equipment. 2. **Durability and Quality:** Overhead cranes are designed to last and are made of sturdy materials. Even a used model can offer excellent performance if well maintained. 3. **Immediate Availability:** A used overhead crane can be available immediately, allowing operations to begin without long waits for the production and delivery of a new model. 4. **Evaluation and Inspection:** Used overhead cranes sold through specialized dealers are often tested and inspected to ensure they are in good operating condition, offering additional security. 5. **Service and Spare Parts:** Brand-name overhead cranes like BITRAVI OMIS have good availability of spare parts and service, even for used models. This ensures that any repairs and maintenance can be handled without difficulty. In summary, purchasing a used 20-ton BITRAVI OMIS overhead crane can be a beneficial choice for companies that need to lift and move heavy loads safely and efficiently, offering significant cost savings without compromising the quality and reliability of the equipment.
