Hydraulic Roundnose Grabs
The hydraulic roundnose grab is specially designed for heavy duty dredging and digging purposes. For very hard soil mixed with rocks. The turning points are equipped with heavy duty bearings.The bearings are double sealed to prevent entering dirt into the bearings. The grabs are manufactured of high wear resistant steel.
The inner side of the scales is smooth, without any abrupt transitions. This minimises the resistance during the digging in to the bottom and also makes it easier to unload sticky materials, like clay.
The knives are manufactured in a round shape with interchangeable teeth for more strength and more impact into the very hard soil.
The grabs can be executed with:
- Mechanical rotator for 270˚ rotation (The mechanical rotator will standard be executed with 200mm height compensation)
- Hydraulic rotator for 360˚ hydraulic rotation
- Hydraulic 360˚ rotation by means of slewing ring and hydro Motor
- Without rotation (fitted with plate and lifting eye(s)
Optional the shells can be executed with a clay ejector to push out clay and other sticky materials.
The grabs can be manufactured in any execution weight and capacity you require.
A suspension link for connection of the grab to the crane can be manufactured according to your requirements.
