Scissor Grab Scissor Grappler Scissor Grab Bucket for Scraping Coal

Product Description Description: The Scissor Grab is a highly efficient material handling equipment designed for loading and unloading granular, small-block bulk cargo such as coal, ore, sand, mineral powder, and fertilizer. It can be attached to cranes equipped with two or four drums, making it ideal for use in ports, vessels, yards, and other industrial sites. The scissor grab features a simple structure, easy operation, wide opening span, high grabbing ratio, and strong cabin cleaning capabilities. Advantages of the Scissor Grab: 1. Combines speed, lightweight, and stability on slopes to maximize productivity, reducing the need for additional trimming equipment like bulldozers. 2. Offers excellent cleaning performance, significantly cutting down unloading time and labor costs, resulting in lower per-ton costs. 3. Designed with an efficient force distribution system, ensuring ease of operation and durability. 4. Provides superior digging and filling capabilities, short cycle times, long service life, and low maintenance. 5. Engineered to withstand extreme working conditions and high usage levels. 6. Known for high productivity and stability on sloped surfaces. 7. Excellent cleaning and digging performance. 8. Long service life—often twice that of similar grabs. 9. Fast closing speed allows for quick cycle times. 10. Stable and reliable operation. 11. Can open almost horizontally, allowing closer access to the delivery chute, reducing material loss and environmental pollution. 12. Lighter weight and higher efficiency compared to traditional long-rod grabs. When you need to transfer large volumes of coal or ore quickly and efficiently with minimal downtime and maintenance, the scissor grab is the ideal choice. 25T Remote-Control Bulk Grab Specification - Grab Type: 25/25T Remote-Control Bulk Grab - Model: YK25 [8-10-12]10B-00 Technical Parameters: - Fit to 25T Crane / Grab Size: Refer to Drawing - Empty Grab Opening Time: 12s - Cubage: 6–12 m³ - Empty Grab Closing Time: 18s - Rated Load: ~16t - Density: ~1.0–2.0t/m³ - Grab Dead Weight: ~9.2t Technical Standards: 1.

Painting: 1. Surface Preparation: Sa2.5 grade 2. Coating Thickness: 80μm (Primer) + 80μm (Topcoat) 3. Top Paint Color: As per Customer Preference Working Principle: - **Closing Cycle**: When the grab opens, the moving board connects with the top beam and separates from the lower beam. The hydraulic system opens, pulling the piston. As the crane hook lowers, the moving board follows, triggering the stroke switch to stop the hydraulic oil. The grab closes as the hook rises. - **Opening Cycle**: Press the remote control, signal is sent to the receiver, and the electromagnetic valve opens the hydraulic circuit. The grab opens as the cylinder extends, allowing the next cycle. Other Technical Parameters: 1. Working Voltage: 24/24V DC 2. Remote Control Distance: >100m (Line of Sight) 3. Frequency: 321MHz (Transmit), 331.7 MHz (Receive) 4. Charger: Input 110-220V, Output 2.2A 5. Battery: 120 hours continuous operation (DC12~24V, new batteries) Remarks: - A buffer device is installed on the hydraulic valve to reduce impact during opening, extending the life of the hydraulic system. - Free accessories included with each 2-4 grab: Hydraulic seals, tools, remote control and receiver, battery, charger, and grease nipples. Quality Assurance: We provide global sales service within 18 months from delivery or 12 months from commissioning, excluding exceptional cases. Imported parts like hydraulic valves and pipe adapters are covered by the supplier’s quality warranty. Documents Provided: - General drawing, wear parts images, part catalog, user manual, and maintenance manual. - One copy of the Product Qualification Certificate (CCS, BV, RINA upon request).
