Scientific Press-in Operation
Press-in Quality Control System for Precise Execution
Using the Press-in Quality Control System, any valuable information for quality assurance, such as press-in force, skin friction, toe resistance, penetration depth and performance time, is available from an on-board computer in real time. All measurements are useful to recognize abnormal factors underground and certify the quality of the completed structure. Load tests which are normally carried out after piling is completed, are being executed during pile installation without extra equipment. The Press-in Quality Control System makes the performance related design of structures possible.

Automatic Press-in Operation System for the Most Efficient Performance
In the Press-in Method, use of the down-stroke / up-stroke procedure is the essential way of press-in operation. By the Automatic Press-in Operation System, an operator inputs the best variables of press-in force, press-in stroke and extraction stroke to the Silent Piler. The system enables the machine to maintain the most efficient press-in performance. Press-in piling work has been shifted from a physically trained experience field to a logically progressed scientific field. The difference between manual operation and automatic operation is illustrated in the press-in data to the right.
GRB System (GIKEN Reaction Base System)
Utilizing the principle of reaction force, all necessary equipment for the piling operation can be supplied on the pile line and the press-in work progresses along the pile line from the start to finish without the need for external staging. Specialized machinery was designed, developed and systemized into the integrated GRB System, which enables the piling operation to be carried out with ease over water, on embankment slopes and along very confined or restricted sites where normal piling rigs or service cranes can not gain access.
