Product Introduction of the mechanical two rope clamshell grabs
The mechanical two rope clamshell grabs is suitable for all kinds of cranes with double lifting device structure, and is mostly used in ports, docks, construction roads and bridges and other industries.
According to the material characteristics, it can be equipped with light, medium, heavy, and super heavy. Suitable for grabbing all kinds of loose accumulations.
Then various cranes. Equipped with two sets of motor reels (i.e. electric hoists), each set of reels leads to a wire rope, one of which serves as the support on the grab balance frame, and the other wire rope passes through the pulleys of the upper and lower beams to form a pulley block, which plays a role in the opening.
Mechanical two rope clamshell grabs are an effective tool for loading and unloading bulk cargo such as yellow sand, coal, ore powder, and bulk fertilizer in various harsh environments.
Mechanical two rope clamshell grabs has a simple structure, a novel opening and closing mechanism, easy to operate, and can accurately complete the opening and closing actions in various states.
Mechanical two rope clamshell grabs adopts a three-dimensional virtual design, and ANSYS software is used for strength analysis and verification. The weight distribution is more reasonable and the service life is longer.
The upper bearing beam of the mechanical two rope clamshell grabs are equipped with lugs, which can be directly connected to the lifting rope shackle of the crane.

如何选择合适的抓斗
- 明确你的目的：
在深入研究选项之前，请明确您的具体要求。问自己：
- 您想处理什么材料？（原木、废金属、石头等）
- 抓斗将执行哪些任务？（装载，分类，拆卸等）
- 它将连接到哪种类型的设备？（龙门起重机、桥式起重机）
- 你抓取的物料比重是多少？抓取的立方体数量是多少？
你的抓斗起重机的吨位是多少？
根据所抓取物料的特性，抓斗通常分为轻型、中型、重型、超重型四种基本型。
| 抓取材料的类型 | 抓取材料 | 容量重量(t/m³) |
| 光 | 焦炭、矿渣、谷物、土豆、中质无烟石灰、水泥、土壤、砾石、粘土、碎砖等。 | 0.5~1.2 |
| 中等的 | 泥炭、大块无烟煤、压实煤、粘土、石灰石、砾石、盐、碎石、砖块、铝土矿、氧化铁薄片、水泥、水中的沙子和砖块等。 | 1.2~2.0 |
| 重的 | 石灰石、重粘土、中小型矿石、硬质岩石、棒状氧化铁、铁矿石、铅精矿粉等。 | 2.0~2.6 |
| 超重 | 大块矿石、大块锰矿、沉积团聚铅矿粉等。 | 2.6~3.3 |
- 配件兼容性： 确保抓斗与现有设备兼容。
- 预算考虑： 抓斗的价格范围是不同的。请根据抓斗的功能和耐用性平衡您的预算。
