What buyers inspect
The details importers check first when they sample long ram jacks.
-
Safety overload valve on every unit
A factory-set bypass valve stops the ram when the rated load is exceeded – fewer warranty claims and no bent rams in the field.
-
Heavy-gauge base and cylinder
Bases are stamped from thick steel plate and cylinders are precision-honed, so seals last longer and oil stays where it belongs.
-
Chrome-plated ram and pump piston
Hard chrome resists rust and scoring in humid warehouses and workshops, keeping the lift smooth for years, not months.
-
Serrated saddle
Cross-hatched saddles grip the lifting point instead of sliding on greasy chassis rails – the first thing inspectors check.
-
Electrostatic powder coating in-house
Our own powder-coating line gives consistent colour batch after batch, and lets you order your brand colour without paying for outside finishing.
-
Clear rating labels in your language
Capacity, warnings and your logo are printed to your artwork – GS/CE or ASME PASE style label layouts available.
How to choose long ram jacks for your market
The questions our sales engineers ask before they quote.
-
Match the crane or press
Choose by stroke and closed length as well as capacity – all three are in each model table and on the engine crane pages.
-
Single or dual pump
Dual pump reaches the load faster; single pump is the economical replacement part.
