**Product 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 with two or four drums and is widely used in locations like ports, vessels, and yards. The scissor grab stands out due to its simple structure, easy operation, wide opening span, high grabbing ratio, and strong cabin cleaning capabilities.
Compared to traditional grabs, the scissor grab offers several unique advantages:
1. Combines speed, lightweight, and stability on sloping surfaces, maximizing productivity and reducing the need for additional trimming equipment.
2. Excellent cleaning capabilities significantly reduce unloading time and labor costs, leading to lower costs per ton of material.
3. Efficient design ensures favorable force distribution and ease of operation.
4. Offers superior digging and filling performance, short cycle times, long service life, and low maintenance costs.
5. Designed to withstand extreme working conditions and high usage levels.
6. Provides high productivity and stability on slopes.
7. Features excellent cleaning, digging, and filling capabilities.
8. Long service life—often twice as long as other grabs in its class.
9. Fast closing speed allows for shorter cycle times.
10. Stable and reliable operation.
11. Can open near horizontal level, allowing it to get closer to the delivery chute, minimizing material loss and environmental pollution.
12. Lighter weight and higher efficiency than traditional long-rod-type grabs.
When dealing with large volumes of coal or ore, the scissor grab is an ideal choice due to its fast and efficient operation, minimal downtime, and low maintenance requirements.

**Painting Details:**
1. **Surface Preparation:** Sand-blasted to Sa2.5 grade
2. **Coating Thickness:** 80μm primer + 80μm top coat
3. **Top Paint Color:** As per customer request
**Working Principle:**
- **Closing Cycle:** When the grab opens, the moving board connects with the top roof beam and separates from the lower one. The hydraulic system opens, pulling the piston. As the crane hook lowers, the grab closes once the stroke switch triggers the valve.
- **Opening Cycle:** Pressing the remote control sends a signal to the receiver, activating the valve. The hydraulic cylinder extends, separating the lower beam and allowing the grab to open for the next cycle.
**Other Technical Parameters:**
1. **Working Voltage:** 24V DC
2. **Remote-Control Distance:** >100m (line-of-sight)
