Product introduction :
The Scissor Grab: An Essential Component for Bulk Cargo Handling
Components Overview:
The scissor grab comprises a meticulous assembly of components, including two jaw plates, rope-operated force arms, a central hinge point, pulley blocks, steel wire ropes, and support ropes. The jaw plates are extended at their hinged ends to form the rope-operated force arms, which share a common central hinge point. Through the orchestrated movement of steel wire ropes and pulley blocks, the grab effortlessly performs opening and closing actions.
1. Operating Principle
Opening Mechanism: To initiate the opening process, the wire ropes at the pulley blocks attached to the scissor arms are slackened, while the support ropes are simultaneously tightened. This coordinated action gradually separates the two jaw plates, enabling the grab to open wide.
Closing Mechanism: For closure, the wire ropes of the pulley blocks are tightened, harnessing the lever principle to amplify force. This results in the gradual closing of the jaw plates, effectively grasping the material. The closing torque progressively increases throughout the closure process, ensuring a clean and thorough pick-up of materials without spillage.
2. Features & Advantages
High-Efficiency Grasping: As the scissor grab closes, its digging force gradually intensifies, aligning perfectly with the force required to engage the cargo. This results in significantly enhanced grabbing efficiency. Additionally, its compact opening and closing cycle saves valuable time.
Superior Grab-to-Weight Ratio: Compared to traditional grabs, the scissor grab boasts a higher capacity-to-weight ratio, enabling it to lift more cargo with the same self-weight, thereby enhancing equipment utilization.
Versatile Application: The scissor grab's compatibility with various crane configurations, including bridge-type ship unloaders and four-rope portal cranes, makes it ideal for handling bulk materials like ore and coal across diverse industries.
Facilitated Cleaning: Thanks to its extensive opening width and enhanced grabbing area, the scissor grab efficiently clears the hold without the need for additional excavation or raking machinery.
Low Maintenance & High Reliability: With fewer pulleys and pins, the scissor grab experiences reduced wear and tear, translating into fewer breakdowns and extended service life.
3. Application Scenarios
Predominantly employed on large-scale bridge-type ship unloaders, the scissor grab excels in the swift and efficient handling of bulk commodities such as ore and coal. Its compact design and agile operation also render it suitable for other scenarios demanding efficient bulk cargo handling.
