Our digger SG Series Diaphragm Wall Grabs & Equipments
SG Series Diaphragm Wall Grabs & Equipments features advanced technology, excellent performance, reliable quality, and easy handling. It is a multifunctional foundation construction machine of high efficiency.
1. High construction efficiency, powerful shutting force The promotion speed of the grab is fast and it is able to make free fall. The opening and shutting time for the grab is 6 seconds on the average with powerful shutting force.
2. Good perpendicularity for the wall The grab design has used long guidance and low center of gravity, equipped with the vice-gear to balance the torque in working condition and to reduce the deviation.
The grab may also be installed with deviation corrector to maintain and repair the wall anytime during working.
3. Advanced electronic surveying system The advanced electronic surveying system can accurately demonstrate the depth and the position direction of the grab on the screen, as accurate as to 0.01 degree.
4. Safe and reliable protection system The cab is equipped with the security operating lever and central supervisory system with the alarm apparatus. The promotion and the release of the cab has the safekeeping security installment. When the grab releases to the bottom of the hole and the pulling force of hoist steel wire reduces to the certain weight, the hoist stops releasing under the control of hydraulic valve, therefore, the steel wire will not release excessively, which is advantageous for the verticality
