Various types of crane buckets and crane grabs , diverse of industrial grab crane solutions

Based on different standards, the crane buckets can be classified into different types. And the general classifications of crane buckets are as follow:

Generally speaking, there are various types of grab buckets and crane grabs based on different standards or classifications in terms of grab shape, power supply , and application, etc.

Grab bucket types in terms of grab shapes

Based on the shapes of grab bucket and crane bucket, there are mainly includes clamshell grab orange peel grab, and cactus grab bucket, etc.

• Clamshell grab is the most frequently used grab bucket,with leaking proof design, equipped on types of clamshell cranes, widely applied for grabbing and lifting silty, clayey and sandy loads and objects such as fertilizer and grains etc. ,Processed clamshell crane grab buckets are available.
• The orange peel grabs are designed with multiple jaws designs from 4 from to 8 tines, which can not be completely and are widely used for large irregular pieces loads handling such as of larger and irregular loads such as, steel scrap, big iron, and wastes, garbage, etc.
• Cactus grab buckets are suitable for both the coarse and fine loads or objects handling with 3 or 4 jaws which can be closed very well in the closed position.

Grab buckets classification in terms of bulk density

Based on bulk density of loading materials, crane buckets and grab bucket can be grouped in light, medium, heavy, and extra heavy crane grab basket.

• Light grab bucket is suitable for loads with bulk density of γ< 1.2t / m³, such as dry grain, little bricks, lime, fly ash, aluminum oxide, sodium carbonate, dry slag , etc.
• Medium grab bucket is suitable for loads with bulk density of γ=1.2t/ m³~2.0t/ m³, such as, gypsum, gravel, pebbles, cement, large blocks, etc.
• Heavy grab bucket is suitable for loads with bulk density of γ= 2.0t / m³ ~2.6 t / m³, such as, hard rock, small and medium-sized ore and scrap steel, etc.
• Extra heavy grab bucket suitable for loads with bulk density of γ>2.6t / m³,such as, heavy ore, scrap steel, etc. .

Crane bucket types in terms of mechanical principals

Based on the mechanical principal, the crane buckets, there are mechanical rope grabs, electric motor grab and hydraulic grab, etc.

• Ropes grab. The mechanical rope grabs can be grouped into single rope grab , double rope grab, and four rope grab,etc.
• Power self-supplied grab buckets are the grab bucket with electric motor, which is not allowed for underwater work.
• Non power self-supplied grab. The non-power self-supplied crane buckets are those electric hydraulic grab buckets and pneumatic type crane buckets,

Clamshell grab & clamshell grab bucket

Clamshell grab is mainly consisted of two integral buckets, which are mainly used on clamshell bucket cranes, such as overhead travelling bridge crane for loose deposits for loading, unloading, shifting, charging and other various operation, with advantages of Cost-effective price, Reasonable structure, Compact design, Favorable performance, Easy and precision control and load position high safety and reliability, etc.

Clamshell grabs can be used for handling loads of light duty, middle duty, heave duty and extra-heavy duty. According to the driving type, clamshell crane buckets can be grouped into hydraulic clamshell grab and mechanical clamshell grab.

Clamshell bucket grabs equipped on clamshell bucket cranes are widely for grabbing dry bulk cargo with efficiency and safety. Based on the type of handling loads, it can be divided into such as ore grab, coal grab, grain grab, wood grab,etc.

Based on the operation characteristics , the mechanical rope grabs can be divided into four rope grab , double rope grab and single rope grab. The mechanical crane buckets for sale with process designs based on the conditions of loads and objects and lifting requirements of clients.

• Mechanical grab with Single Rope Grab design- The opening and closing of the mechanical crane buckets are using the same rope, that is the single rope grab with simple winding mechanism and relatively low productivity.Single rope grab is unable to open during lifting in the open air, hand and remote control type can be realized to open in the air.The single rope grab is applicable for loads grabbing and moving in underwater and ground operations .
• Mechanical grab with Double Rope Grab design -Double rope grabs, equipped on bridge overhead cranes are widely used in ports ,docks ,power plants,chemical industry ,for lifting and transferring loose deposit ,such as ore ,coal ,slag,cereal,light reactor and other,etc.
• Mechanical grab with Four Rope Grab design- The four rope grab and four cable grab are equipped with two groups of lifting drums for loading and unloading various loose accumulation and irregular shape materials ,such as, scrap, refuse, gravel etc., suitable for steel mills refuse plants, port and railway and other industries, etc.
