The trolley is provided with a reel for up to 50 metre of 8x17 hose
Both models have a side attachment for a second man, the bigger trolley is also provided with a container
for outfits and of an hook for holding the second hose.
ATTENTION:
If more than one cylinder is mounted on a trolley make sure that they all have same dimensions
•
and capacity in order to grant stability of the system
In case of separate purchasing of cylinder always check with Spasciani that the dimensions of the
•
cylinder you want to mount on the trolley is compatible with the fixing systems on the trolley
