A special grab bucket for underwater dredging operations matched with crane ships. According to the lifting form of the supporting crane, it is divided into four rope, double rope mechanical form and hydraulic transmission form. According to the different underwater working conditions, it is divided into:
1) Double flap grab for dredging, dredging or catching pebbles
2) Heavy-duty grab for excavating clay, gravel and slab soil
3) Giant fishing grab for fishing and grabbing large stones
The radio remote control grab is a bulk grab that applies radio remote control technology to a single rope grab. It is often used with single hook cranes. It solves the difficulty of single rope grabs with low work efficiency and high operating strength. It is especially suitable for single hooks. Model cranes and marine cranes are reliable and easy to operate. Using radio control, it can open a bucket to unload at any position in the air.
The container spreader utilizes ingenious mechanical mechanism to realize the automatic unlocking and locking of the container spreader without manual operation, which greatly improves the work efficiency and can conveniently lift standard 20-foot and 40-foot containers.
The rotary hydraulic spreader is specially designed for gantry cranes, bridge cranes, floating cranes and portal cranes. Suitable for ISO standard 20-foot and 40-foot container loading and unloading operations, with a rated lifting weight of 30.5 tons. The container spreader is driven by a hydraulic system. It is a kind of container spreader with high degree of automation and operation efficiency. It has the function of rotating the container position by itself. It is especially suitable for occasions that require high container rotation operations and high loading and unloading speeds.
When enterprises purchase grab cranes, they must choose the appropriate grab type and model. Welcome to consult us.
