Tong Grab Paina

1.High Efficiency & Full Capacity

The Paina grab bucket delivers consistent high performance with a filling rate of 95%–100%. It maximizes the amount of material captured in each cycle and increases overall handling efficiency.

2.Long Service Life

The design uses bearing-grade steel bushings and wear-resistant alloy blade plates. These components extend the service life to four to five times longer than traditional grab buckets and reduce long-term maintenance needs.

3.Versatile Working Conditions

The pulleys use a multi-layer sealing system that protects against dust and water. This structure supports stable operation in both land-based and underwater environments and ensures reliable performance in demanding conditions.

4.Clean & Stable Operation

The blade plate gap is controlled within 0.3 mm–1 mm. This tight tolerance prevents material leakage, keeps the work area clean and maintains steady operation during continuous loading tasks.

The Paina grab bucket combines high efficiency, extended durability and wide adaptability. It provides a reliable and cost-effective solution for handling bulk materials across various industries while keeping performance stable and maintenance simple.

Ciri-ciri dan Aplikasi Produk

Features：

1.The grab adopts a well-engineered structural design that shortens the lower load-bearing beam while ensuring high strength and reduced weight.

2.The ratio of material grabbing weight to grab self-weight reaches 1.5–1.92. The filling rate is as high as 95%–100%. It provides strong grabbing performance and supports highly efficient material handling.

3.The struts use a closed welded structure with independent force transmission, offering excellent stability and strong lateral bending resistance.

4.Wear-resistant and durable components are applied, including bearing-steel bushings and 40Cr pins, extending service life by 3–4 times..

5.The grab features excellent sealing performance and can operate underwater.

Applications​

Paina grab buckets are widely used in ports, terminals, freight yards, and power plants. They are suitable for handling various loose materials such as coal, grain, slag, and ore.

Butiran Produk

In terms of structure, the Paina grab bucket uses a closed welded strut design with independent force transmission. This structure keeps the grab stable and gives it strong resistance to lateral bending. It also provides a solid base for consistent performance in daily operation.

The key hinge points use bearing-steel bushings and 40Cr pins. These parts offer high wear resistance and strong load capacity. They help the grab handle long working hours while keeping the joints tight and reliable.

The cutting edges are made of special wear-resistant alloy steel and receive hardfacing treatment. This process increases impact resistance and improves wear performance. It also makes welding repair simple and fast when maintenance is needed.

The sheaves use high-temperature-resistant bearings and double rubber seals. This creates a multi-layer sealing system that blocks dust and moisture. It also reduces the chance of contamination and extends the service life of the rotating parts.

The overall structure is designed to resist deformation and misalignment. It stays stable even in harsh working environments and ensures long-term reliable operation. This stability supports consistent performance and reduces downtime.

How to choose the appropriate specification of the Paina Grab Bucket according to operational requirements?
The selection should consider material density, required single-load capacity, the rated lifting capacity of the matching crane, and the working environment (land/underwater). Based on these working conditions, a customized solution can be provided..
It is mainly suitable for small granular loose materials such as coal, grain, slag, and ore. It can also be adapted for handling certain powdery materials according to specific requirements..
Focus on inspecting the bearing steel bushings at critical hinges, checking wear on the 40Cr pins, regularly cleaning the pulleys, and checking the sealing performance. Lubricate all moving parts with grease as required..
The key lies in the use of bearing steel bushings, 40Cr pins, and special wear-resistant alloy steel blades. The blades are reinforced with overlay welding, greatly improving wear resistance and impact resistance of the components.
