| We are producers of all kind of grabs with volumes up from
0,1 m3 to 50 m3 and up to 30 tons dead weight.
The pre-sorting of the various types is as follows:
|
|
Rope Grab
A rope grab works by means of a pull of the rope over a pulley (closing ropes are reeved in several times in the grab rope pulleys). Hereby is a distinction between single-line, double-rope or four-rope grabs (depending on the numbers of closing and holding ropes existing at the crane).

Motor Grab
A motor grab has its own drive unit consisting of motor, pump and hydraulic control elements. The power supply comes from the crane via an electrical power feeding. The grab only has to be connected with the crane hook and the electrical power feeding and than it is ready for operation.

|
Hydraulic Grab
A hydraulic grab does not have an own drive unit, the power comes direct from the hydraulic dredger or from the hydraulic crane via the hydraulic hoses. |
