Protection Tube
The
Blocklift gas spring operates in the same principle as the Lift gas spring.
Due to an integrated valve the cylinder of the gas spring is seperated into
two different pressure chambers. The valve works as an transfer channel of
the gas and/or oil. When the valve is closed the transfer channel is closed
either and the relevant medium cannot pass into the other pressure chamber
thus the gas spring locks. By pressing the release pin the integrated valf
will open and and the medium passes through the valve and floods to the other
chamber thus the gas spring unit can be moved into any desired position. When
your desired position is reached just leave the release pin and the gas spring
will lock immediately because the valve is closed. In this manner a Lift becomes
a Blocklift.
Blocklift gas springs are available in 3 different Locking Type variations
a)
Spring Blocking
b) Rigid Blocking in Extension
c) Rigid Blocking on Compression
The table below shows standard dimensions which ensure optimum function and
service life. We welcome the opportunity to produce custom products.
