DHG is a diaphragm wall grab which is rope suspended and operated hydraulically. The 80 / 120 t closing force and 6~10 second* shovel

opening / closing time are activated by a cylinder which is installed vertically inside of base body. High closing forces in combination with the

possibility of multiple grabbing at the trench bottom result in high excavation rates even in dense and very hard soil strata.

The new developing DHG/SF & DHG/CF, equipped with Flap Control System, which allowed operator reading the deviation for both X

and Y directions from excavation monitor in cabin, and adjust the grab position instantly through 8 or 12 numbers flaps to correct thedeviation.

Grab Control System GCS

Deviation on the excavation monitor

Flaps control system steering the excavation

The GCS grab surveying system continuously monitors the

verticality of diaphragm wall trenches during excavation.

An inclinometer for measuring the inclination of the

trench is built into the grab. Data transfer from the grab

to the operator's cabin is by heavy-duty electrical cable,

which is automatically reeled off and on by a hydraulicallyoperated cable recoil system. By using heavy-duty

electronic components for data collection, processing and

visualization, operation of grab is safeguarded even under

extreme conditions.

Data are visualized on a 10 inches touch-screen monitor

with a luminous intensity of 350 candelas. In order to

increase the measuring accuracy, it is recommended to

carry out a separate survey of trench after it's completion.

All result can be printed out on a printer. (The GCS system

is optional.)
