With the continuous development of the construction industry, life will often use a lot of machinery and equipment, has brought a lot of convenience for the engineering and construction, including the use of the scope of grab is very broad, in many fields are used, and for the use of crane (grab), is mainly used in port, dock, the station yard, mine etc. to carry all kinds of bulk cargo, logs, minerals, therefore, compared with the traditional use of manual unloading of goods more convenient, so, what are the main characteristics of grab crane in use.
Grab bucket:
1 、 grab crane is mainly used for automatic extraction of a mechanical equipment, and in the crawl and unload material movements are operated by the ship unloader driver
Therefore, the heavy labor of the workers is avoided, the auxiliary working time is saved, and the loading and unloading efficiency is greatly improved
2. Grab crane is mainly operated by using grab bucket, so it is easy to operate, easy to use, simple to maintain, and also can improve production safety by using grab crane.
Choose the power form of grab according to the crane: first select the power form of grab according to the crane. According to the definition of grab bucket: grab bucket is the device under the crane, so even the most advanced grab, but also inseparable from the crane and independent work. On the other hand, the more advanced and larger tonnage ship unloader can not be separated from the grab bucket and has production efficiency. So what kind of crane should with what kind of grab, the wrong can not be used, with large overload can not be used. Grab
For example: crane hoisting drum is single, with mechanical grab, grab only with a single cable, if equipped with four rope grab, grab the work up again; for example: Crane rated lifting weight is 25t, to grab, grab hold only with weight and weight of =<25t, with the crane overload safety.
