§4 Structure of components
4-1
Base
The base is made of flat steel to enable a specimen to touch the base horizontally. Its main column
is mounted on the upper face and its lifter and control unit are mounted. The base is perforated at
its corners so that it can be fixed to the floor by grip anchoring (or anchor bolts).
4-2
Main column
The main column is fixed to the base vertically and a height setting scale is mounted at the front
center.
4-3
Drop releasing device
The drop releasing device is equipped with the electromagnetic holder for coupling the specimen
supporting base, height setting pointer, and the fixing knob for position holding. Power is supplied
to the electromagnetic holder to drop the specimen according to a signal from the control unit.
4-4
Specimen supporting base
The specimen supporting base is provided with two pneumatic pen cylinders for fixing and releasing
a specimen. The drop height is set to the center axis of these pneumatic pen cylinders.
4-5
Height setting pointer
The height setting pointer is mounted on the drop releasing device side.
4-6
Pneumatic pen cylinders (for fixing and releasing a specimen)
The pneumatic pen cylinders for fixing and releasing a specimen are operated by an air pressure as
the drive source.
If the power supply is turned off while fixing a specimen, the pneumatic cylinders hold their position
so that the specimen does not drop to ensure safe operation.
4-7
Contacts
Two kinds of contacts shown below are attached as accessories.
Even if a specimen is light, it cannot always be held depending upon its profile and its gravity center
position. If you desire the other contacts satisfying your profile requirement, we will manufacture
them within a possible range. Please contact us in such a case.
