I am selling two used Omis overhead cranes. The overhead cranes are of the double girder type and have a lowered hoist trolley. This allows the used overhead crane to be used on extremely low warehouse heights. If the space you have between the runways and the ceiling is very low, this is the used overhead crane for you. Between rail and ceiling it occupies only 680 mm. One overhead crane has a gauge of 18.5 m, the other 18.7 m. They are currently not working even if they are periodically inspected. They are equipped with a double speed Donati hoist. They are like new. ### Operating Principle of an OMIS 20 ton DOUBLE GIRDER overhead crane The overhead crane is a type of industrial crane mounted on rails above a work area. The OMIS 20 ton BIBEAM 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 phases: **1. Overhead 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. - **Cart:** The cart slides along the beam and can move horizontally to place the load over the desired work area. - **Lifting Hook or Bucket:** The lifting hook or bucket is used to grab 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 the entire work area to be covered. - **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 an 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 can be remote or on-board control, depending on the design. **4. Safety:** - **Protection Systems:** The overhead cranes are equipped with safety systems such as overload sensors, automatic brakes, and height limiters to ensure correct operation and prevent accidents. ### How to Use 1. **Preliminary Inspection:** Before use, perform a complete inspection 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 lifting hook or bucket. Make sure the load is well balanced and safe. 3. **Movement Control:** - **Longitudinal Motion:** Use the control to slide the beam along the rails to position the load over the desired area. - **Transversal Movement:** Move the trolley along the beam to place the load in the exact position. - **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 the overhead crane operates safely and reliably. ### When It Is Best to Buy an OMIS 20 ton BIGISTER Overhead Crane 1. **Management of Heavy Loads:** If your company needs to lift and move heavy loads, such as construction materials, heavy equipment or large industrial components, a 20 ton overhead crane tons is essential. 2. **Large Work Spaces:** If you work in an industrial or warehouse environment with large spaces and need equipment that can cover large areas, the overhead crane is the ideal solution thanks to its ability to move along the 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 It Is Worth Buying a Used Overhead Crane 1. **Economic Savings:** Buying a used overhead crane is often much cheaper than buying a new one. This is especially beneficial if your budget is limited but you need reliable, high-capacity equipment. 2. **Durability and Quality:** The overhead cranes are designed to last over time 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 you to start operations without long waits for the production and delivery of a new model. 4. **Assessment and Overhauling:** Used overhead cranes sold through specialist retailers are often tested and overhauled to ensure they are in good operating condition, offering additional safety. 5. **Assistance and Spare Parts:** Brand overhead cranes such as BITRAVI OMIS have a good availability of spare parts and assistance, even for used models. This ensures that any repairs and maintenance can be handled without difficulty. In summary, purchasing a used BITRAVI OMIS 20 ton overhead crane can be an advantageous choice for companies that need to lift and move heavy loads safely and efficiently, offering significant cost savings without compromising quality and reliability of the equipment.
