- The head form support can be raised or lowered up to 10 inches (25.4cm).
The ECE-22 is operated by an air cylinder that moves the drop mass
device (10 Kgs) to the drop height desired of 0.6 meter ( 60 Cm ). It supports the use of different
sized head forms, helmet geometry, size's, and various lengths of webbings.
By having an adjustable supporting arm you can adapt all kinds of helmets to the ECE-22 and respect
drop heights requested by many different standards.
- The hook holder device of the helmet support can be moved forwards and backwards to position the alignment to
complete the helmet positioning before executing the test.
The red button is used to lock the hook system in place. To remove the hook, simply pull the red button towards you.
Pushing the button back will secure the hook helmet support back into place.
- The head form attachment device has a red button that is used to lock or unlock the device in place.
This gives the operator the ability of easily removing and replacing the complete head form with helmet from the machine.
- The handle command control's the pneumatic air cylinder in the back of the
machine. It has a UP, Neutral and Down position and is used to modify the height of the release mechanism.
- The release system sends the command that drops the mass
from the top to the down position in order to perform the impact test
on the helmet. The button must be pressed for a few seconds to give the machine time
to react to the drop command.
- The sensor device will read the real time displacement of the test sequence. It has a displacement
capability of 0 to 15 cm and needs to be connected to the power conditioning unit of the machine.
The sensor is the most sensitive and delicate part of the machine, which is why it was designed so close to the main frame.
This will help protect it and minimize the chance of an accident during testing.
The sensor comes with a calibration device that should be used to verify the accuracy of results.
- The air entry outlet for compressed air. The machine will need to be connected to a compressor to work properly.
The pressure should be between 80 PSI (min) and 150 PSI (max). That air entry device has a small container that accumulates water
that is separated to avoid any moisture getting into the air line system of the machine. The container needs to be emptied manually, so
it is important to keep track of the water level of the container. Simply press the release water button on the water receiver bottle
to have the water evacuate the device.
- Depth: 33 inches(83.82 cm)
- Width: 23 inches(58.42 cm)
- Height is adjustable:
- Min: 83 inches(210.8 cm) - as shipped
- Max:
***The weight of the machine without the head form: 50 Kgs and the machine
including the wood crate for overseas shipment is: 160 Kgs
- The drop mass weight(10 kg) is made out
of steel, covered with none corrosive plating to protect the device.
- The release mechanism of the machine is used to retain the drop mass of 10 kg in place before the test.
- The main frame of the drop assemble guiding system of the machine. This section includes the bottom stopper support,
long rod guide as well as head form attachment. The complete main guiding support with all the parts that represent the pre-load of the
helmet prior the test should be 15 kg (including the head form). To make sure that all head forms (regardless of size or weight) respect
the 15 Kg specification an additional ring that comes with each head form can be installed.
- The EN 960 full Urethane head form (sold separately).
This head form conforms to the ECE-22 requirements EN 960 and is available in various sizes.
All the head forms come in different weights and sizes. To meet the pre-load requisite of the ECE standards of 15 Kg
a dedicated ring is made for each size of head form. This ensures that they are all the same mass when attached to the machine main frame guiding system.
- The bottom pedal is used to move the guiding system UP. This makes it easier to remove or re-install the complete
head form with helmet from the machine. It is also recommended you remove the drop mass on the UP position with your pneumatic device (section 4, 11, 12)
so that you will have less weight to carry during this process.
- The power conditioning unit of the sensor
device. This unit needs to be connected to a 115 VAC/60Hz or 220VAC/50Hz power source. The
sensor and the electronic conditioner box connect to this device. A BNC
connector output is also required to connect to a computer system in order to measure the real time displacement.
Cadex Acquisition software has been developed to monitor this signal system.
- The pneumatic air cylinder allows the drop mass
to be moved up or down. The air cylinder will need a minimum air pressure as described in
section 7.
- This leaver allows you to lower or raise the head form support (section 1).
- The supporting legs are adjustable and should be used to make sure guiding system is level.
The guiding system is the most important part of the machine so it will be more important to make sure it is level, rather than the machine frame.
