Product Introduction
Product Details
The wheel-type rotating 20ft container spreader is a special equipment for loading and unloading 20ft containers in ports, docks and other places. The following is a product introduction:
Structural Composition
Spreader frame: Made of high-strength steel, it has high strength and rigidity, and can withstand the weight of the container and various loads during the lifting process.
Pulley block: Composed of multiple pulleys and steel wire ropes, the configuration of the pulley block allows the spreader to effectively reduce the required lifting force during lifting and lowering, improve the working efficiency of the lifting mechanism, and ensure the smooth lifting and placement of the container.
Rotating mechanism: Driven by a deceleration motor, the small gear drives the slewing bearing to complete the rotation. Each spreader is equipped with two sets of drive mechanisms to make the spreader rotate. If any one of the deceleration drive mechanisms fails, the other can make the spreader rotate, ensuring the normal operation of the equipment.
Twist lock: Installed on the four corners of the spreader, it is used to connect and lock with the corner fittings of the container to ensure the safety and stability of the container during lifting. The twist lock adopts a floating pin type, allowing for a certain range of swing, and can accurately insert the lifting holes on the container.
Guiding device: Generally a guide plate type, when the spreader approaches the container, the guide plate can assist in positioning, so that the spreader and the container's corner fittings are accurately aligned, facilitating the insertion of the twist lock into the container's corner holes.
Technical Parameters
Rated lifting capacity: Usually around 35 to 41 tons, which can meet the lifting needs of 20ft containers.
Lifting speed: Generally around 0-30m/min, which can be adjusted according to the actual working conditions and crane configuration.
Rotation speed: Freely selectable within the range of 0.5～2r/min.
Extension time: Usually around 30 seconds, which can quickly complete the extension and retraction of the spreader, improving work efficiency.
Twist lock action time: Less than 1 second, fast action, improving work efficiency.
Self-weight: Generally around 5-8 tons, the specific weight varies depending on the specifications and configuration of the spreader.
Performance Characteristics
High-efficiency operation: The telescopic mechanism can quickly adjust the length of the spreader to adapt to different specifications of containers, reducing the time for changing spreaders and improving work efficiency.
Safe and reliable: The twist lock can firmly lock the container, ensuring safety during lifting. At the same time, the spreader is also equipped with various safety protection devices, such as overload protection and limit protection, to prevent safety accidents caused by misoperation.
Easy operation: It is usually equipped with an advanced control system, and the operator can conveniently control the extension, lifting, and lowering actions of the spreader through the control handle or buttons in the crane cab.
Flexible rotation: The rotating mechanism allows the spreader to achieve ±360° full rotation, making it easy to flexibly adjust the orientation of the container in a limited space, improving the flexibility and adaptability of the operation.
Anti-swing performance: Some wheel-type rotating 20ft container spreaders are also equipped with an anti-swing system, which can effectively reduce the swing of the container during lifting, improving the stability and safety of the operation.
Scope of Application
Mainly applicable to the loading and unloading and handling operations of 20ft containers in ports, docks, logistics warehouses, container yards, etc. It can be used with container gantry cranes, shore container cranes and other lifting equipment to achieve efficient lifting and stacking of containers.
