When choosing the proper system for a specific application, several points must be considered: Puller Reach Puller reach is the available distance between the pulling surface of the jaw and the jaw head of the puller. This distance varies and decreases as jaws are opened. When choosing a puller, make certain the reach is sufficient …

CRV STEEL also named Chromium-vanadium steel, is a group of steel alloys incorporating carbon (0.50%), manganese (0.70-0.90%), silicon (0.30%), chromium (0.80-1.10%), and vanadium (0.18%).Some forms can be used as high-speed steel.Chromium and vanadium both make the steel more hardenable.Chromium also helps resist abrasion, oxidation, and corrosion.Chromium and carbon can both improve elasticity.

Hydraulic power is one of the safest methods for applying force when used correctly. Below we have provided several precautions which pertain to hydraulic puller systems: DO NOT touch or handle hydraulic hoses or fittings with pressure in the system. DO NOT make any electrical adjustments with electrical power active in the system. DO NOT …
