Trimming grabs are a new type of bulk grab, which is suitable for double-drum cranes for loading and unloading iron ore, coal, bulk fertilizer and other materials.
Trimming Grabs are characterized by novel structure, easy operation, light weight and high loading ratio. When the trimming grabs are loaded with iron ore, the ratio can reach 1:2.5.
The opening and closing strokes of the trimming grabs are short.
Advantages of Trimming Grabs
1.High grab ratio
2.High efficiency: Not only does improving the gripping ratio greatly improve production efficiency, but the gripping force of the scissor grab is small when it is fully opened and starts to grab the goods. With the closing of the grab, the digging force continues to increase, which is just the same as the digging force required to grab the goods, so the gripping efficiency is greatly improved. Only a smaller opening and closing stroke is required to complete the closure, saving closing and opening time and improving efficiency.；
3.Conducive to clearance: due to the large opening of the scissor grab, the grabbing area of each bucket is 60% higher than that of the long strut grab, and no excavator or stacker is required to complete the clearance work.
4.Low failure rate: Due to the small number of shear grab pulleys and fewer pins, this reduces the failure rate of some wearing parts.Due to these advantages of scissor grab, many large bulk cargo grabbers in foreign ports have adopted scissor grab.

Bagaimana untuk memilih grab yang betul
- Jelaskan tujuan anda:
Sebelum mendalami pilihan, sila jelaskan keperluan khusus anda. Tanya diri anda：
- Apakah bahan yang anda ingin berurusan? (Balak, besi buruk, batu, dll.)
- Apakah tugas yang akan dilakukan oleh grab? (Memuatkan, menyusun, membongkar, dsb.)
- Apakah jenis peranti yang akan disambungkan? (Kren gantri, kren atas)
- Apakah graviti tentu bahan yang anda ambil? Bilangan kiub rampasan?
Berapakah tonase kren anda yang dilengkapi dengan grab?
Mengikut ciri-ciri bahan yang direbut, rebut biasanya dibahagikan kepada empat jenis asas: ringan, sederhana, berat dan super berat.
| Jenis bahan untuk direbut | Ambil bahan | Berat kapasiti(t/m³) |
| Cahaya | Coke, slag, bijirin, kentang, kapur antrasit berkualiti sederhana, simen, tanah, kerikil, tanah liat, bata pecah, dsb. | 0.5~1.2 |
| Sederhana | Gambut, kepingan besar arang batu antrasit, arang batu padat, tanah liat, batu kapur, kerikil, garam, kerikil, batu bata, bauksit, kepingan oksida besi, simen, pasir dan batu bata dalam air, dsb. | 1.2~2.0 |
| berat | Batu kapur, tanah liat berat, bijih kecil dan sederhana, batu keras, oksida besi berbentuk rod, bijih besi, serbuk pekat plumbum, dsb. | 2.0~2.6 |
| Berat badan berlebihan | Bijih besar, bijih mangan besar, serbuk bijih plumbum terkumpul sedimen, dsb. | 2.6~3.3 |
- Keserasian aksesori: Pastikan grab serasi dengan peralatan sedia ada.
- Pertimbangan belanjawan: Julat harga grab adalah berbeza. Imbangkan bajet anda berdasarkan fungsi dan ketahanan grab.
- Komen dan cadangan: Penyelidikan dalam talian, baca ulasan pengguna dan dapatkan cadangan daripada rakan industri.
- Pergi ke pengilang kren untuk pemeriksaan dan ujian di tapak sebelum membeli: uji rampasan dalam keadaan sebenar sebanyak mungkin. Nilai prestasinya, kemudahan penggunaan dan kefungsian keseluruhannya.
Perlu diingat bahawa memilih rampasan yang betul memerlukan keseimbangan antara kefungsian, keselamatan dan kos. Dengan mengambil kira faktor-faktor ini, anda akan menemui rampasan sempurna yang boleh meningkatkan produktiviti dan memastikan operasi lancar.
