The hammer grab is the most important tool in pile construction and it determines the drilling progress. The LEFFER hammer grab combines the advantages of a number of good hammer grabs and, due to its special characteristics, is a universial hammer grab of top class.These are essential advantages:The grab has no wear-prone cable pulleys.The closing force is produced by a scissor system which is insensitive to wear and dirt.There is no closing cable subject to frequent replacement inside the grab.Opening of the jaws is assisted by a pretensioned spring, so that adhesive soils are dumped by forcefully striking open the jaws.The body of the grab is streamlined, which ensures a high fall velocity under water.Additional side pockets on the grab's lower part increase the filling capacity of ...

LEFFER has developed an attachment for excavators which is connected to the piling guide. Qperation and hydraulic supply is effected normally from the excavator.Two vibrators attached to the device effect the necessary compaction of the concrete when pulling the driven-in tube. The clamping collar can be hydraulically unlocked and opened towards the front so that the piling unit can be pulled away from the driven-in tube.The open clamping collar enables efficient application of the piling unit, often working on two or three piles at the same time.
