A single rope grab bucket uses the same wire rope to support and control the opening and closing of the bucket, with these actions managed alternately through a locking device. While the winding mechanism is straightforward, this design typically results in lower production efficiency.
The single rope grab consists of several precision components, including a hanging beam, wire rope, slide bar, upper and lower support beams, slide group, support rod, and bucket. It grasps and releases materials through the tension and friction of the rope.
During operation, the grab is positioned above the target material. The cooperation of the pulley and elastic elements enables the grab claws to close around the material as the slide descends, then lift to secure the load.
Single rope grabs are ideal for cranes with only one lifting drum and are suited for both underwater and land-based stacking operations. With its simple structure, lack of a power source, and ease of maintenance, the single rope grab is perfect for environmentally friendly loading and unloading in port operations. OUCO can also provide you with a single rope remote-controlled grab for even more convenience.
If you are simply using a grab to replace manpower and are looking for a more economical lifting alternative, the Single Rope Grab is the best choice for you.
A two-rope clamshell grab bucket is designed for handling materials like gravel, sand, and cement clinker, commonly used in ports, docks, and construction sites. This type of grab bucket is compatible with cranes equipped with two hoist drums, such as double-wire gantry cranes, floating cranes, port cranes, and double-hook overhead cranes.
In this setup, one wire rope group supports the balance frame, while the other passes through the pulleys on the upper and lower beams, forming a pulley block that controls the opening and closing of the grab bucket.
Compared to single-rope grab buckets, two-rope grab buckets offer greater capacity and faster material handling speed.
The 4-rope Orange peel grab is an efficient tool used for loading and unloading various bulk materials like pig iron, ore, coal, and garbage, especially in harsh environments. It features a simple structure with a four-point suspension system, which enhances stability and allows for high productivity in material handling tasks.
The grab is designed for use with cranes that have two hoisting drums, making it suitable for heavier loads and more challenging applications. Its versatility allows it to handle a wide range of materials, including scrap metal and wood chips, the lower bearing beam of the OUCO four-rope grab is shorter, stronger and lighter. and its optimized structure results in low maintenance costs.
The grab’s design enables precise opening and closing actions, making it highly reliable in ports, mining, metallurgy, and waste treatment plants.
While two-rope and four-rope grabs serve similar functions, they differ in construction and application.
Two-rope grabs are durable and straightforward, ideal for handling a variety of common materials. However, they may not operate as smoothly under heavier loads. In contrast, four-rope grabs offer greater stability and balance, thanks to the combined action of the cantilever rope and the main reel rope.
The choice between these grabs largely depends on the crane’s rated load capacity. Smaller cranes typically use two-rope grabs, while cranes with a load capacity of 10 tonnes or more often require four-rope grabs for better performance.
For cranes with a single hoisting drum, a single-rope mechanical grab is an appropriate choice, as four-rope grabs are not compatible.
If your crane is equipped with two hoisting reels, you have the option of using either a two-rope or four-rope grab. For heavy-duty tasks like dredging, a four-rope grab is recommended and can also be lifted by two cranes if necessary.
It’s crucial to ensure that the combined weight of the grab and the material being handled does not exceed the crane’s Safe Working Load (SWL). Exceeding the crane’s maximum load capacity can compromise safety.
