Ram tonnage is the shopping ladder
VEVOR US porta-power kits on this site publish 4, 10, and 12 ton ram capacities for push, pull, lift, bend, and straighten setups with extensions. PortaTons picks the smallest class that covers your required tons on the ram path.
Why the spreader gate exists
The same kits often list a hydraulic spreader near half a ton. Using the 12 ton ram label for jaw spreading is unsafe shopping math — duty code 2 returns NO_MATCH above ~0.5 ton.
Capacity shrinks with geometry
Manufacturer manuals for multi-tube setups warn that stacked extensions and offset loads reduce usable force. Size with margin; confirm the live listing; keep clear of pinch points; never support a vehicle on the ram alone.
