The grapple is a powerful double girder overhead crane equipped with a clamshell bucket that can be used frequently. According to the shape of the bucket, crane buckets can be divided into clamshell buckets, orange peel buckets and cactus buckets. Crane bucket is a tool used with material handling cranes, mainly designed to move fine powdery and bulk materials such as chemicals, fertilizers, grains, coal, coke, iron ore, sand, building materials in the form of particles and crushed stone. etc. The grab bucket crane has many types, our company equips the crane bucket with standard electric lock as the switching mechanism, the grab bucket crane can be considered that the closed drum moves into the bucket, due to its closing with huge gripping force, it is used to grab hard materials such as minerals, etc.
Grab bucket crane with Crane Bucket A bucket with a bucket consists of two or more bucket jaws that can be opened and closed together to form a material holding space. According to the performance, the mechanical bucket can be divided into single rope bucket and double rope bucket, which is the most common. The single rope grapple can be used for subsea and shore operations to grab and move material.
The single rope grip only applies to a crane with a rotating lifting drum. The double rope gripper is applied to cranes equipped with double hoist structure, which are mainly used in the construction of ports, docks and bridges.
The grab bucket crane is mainly used on cranes equipped with a patented maneuvering mechanism for loading and unloading material at any height. Increasing leverage force to bring the jaw closer to the material to be gripped, the closing force of which is increased when closing, and the scissor bucket can grip materials completely without loss, and can be used mainly on large deck ships with loading. Depending on the number of jaw plates, it also includes a single jaw grip and a dual jaw grip, which are used in the most popular ones. According to the improved experience of this example, in the future design of the double-drum grapple, the length of the balance beam of the bucket and the length of the intermediate drum rod should be in reasonable proportion. It is also possible to use 2 types of steel cables according to the direction of the coil helix (1 swivel cable on the left, 1 cable on the right). It can also prevent the cable from loosening and breaking during operation.
