What types of lotus grabs are there

- Classified by the number of grasping petals:

    - Four - petal lotus grab: It has four grasping petals and is suitable for grasping some regularly - shaped and relatively small materials. It is often used in some fine - operation scenarios, such as grasping regular metal products in small - scale waste recycling stations.

    - Five - petal lotus grab: This is a relatively common type. The grasping force is well - balanced, and it can adapt to a variety of materials and working conditions. For example, it is widely used in scenarios such as grasping construction waste on construction sites and grasping bulk ores in ports.

    - Six - petal lotus grab: With a relatively large number of grasping petals, it has a greater tip - grasping force and is suitable for grasping hard - textured and large - volume materials, such as grasping scrap steel in large - scale steel plants.

- Classified by the shape of grasping petals:

    - Semi - enclosed grasping petals: Shaped like a shell, it is suitable for grasping formed medium - to - large - sized materials, such as wood and used auto parts. When grasping such materials, the semi - enclosed grasping petals can better hold the objects and prevent them from slipping.

    - Fully - enclosed grasping petals: When the grasping petals are closed, they can form a relatively closed space, which is suitable for grasping trivial and small materials, such as domestic waste, grains, and sand. It can effectively prevent materials from falling during the grasping and handling process.

- Classified by the fixed form of the oil cylinder:

    - Built - in oil cylinder type: It has a relatively low overall height and a compact structure, which is suitable for places with limited indoor height. For example, when carrying out material - grasping operations in some factory buildings, it will not be limited by the space due to the excessive height of the equipment.

    - Exposed oil cylinder type: The overall height is relatively high, and the oil cylinder is exposed outside, which is convenient for maintenance and repair. It is suitable for outdoor open - space places where there are no strict restrictions on the equipment height, such as open - air ports, mines, and other working environments.

- Classified by working conditions:

    - Single - axis swing without rotation: It is suitable for some working conditions where the rotation function is not required, but the grab needs to swing flexibly within a certain angle range. For example, when grasping materials in narrow passages or corners, the single - axis swing can better adjust the grasping angle.

    - Double - axis swing without rotation: It can swing in two directions, increasing the flexibility and adaptability of grasping. It can be used in some places with complex terrains and irregular material distribution. For example, when grasping materials in mountainous areas or pitted areas, the double - axis swing can make the grab better approach the materials.

    - Single - axis swing with rotation: In addition to the single - axis swing function, it can also rotate 360 degrees. It is suitable for scenarios where materials need to be grasped and transported in different directions. For example, in large - scale warehouses, the grab can quickly and accurately grasp goods in different positions through rotation and swing.

    - Double - axis swing with rotation: It combines the functions of double - axis swing and rotation, offering the highest flexibility and adaptability. It can work under various complex working conditions and is widely used in places such as ports, railways, and waste treatment plants to meet the material - grasping requirements in different positions and directions.

    - Double - axis fixed: The two axes of the grab are fixed without swing and rotation functions. It has a simple structure and is suitable for some places where the working conditions are relatively fixed and the requirements for grasping positions and angles are not high. For example, it is used for material grasping in fixed positions in some automated production lines.
