` Single acting, load return
` Mechanical lock ring feature allows for
load holding for extended periods
` Compact, low height design suitable for
vertical lifting applications only
` Threaded piston with tilting saddle otted as
standard to reduce the risk of side loading
` Nitrocarburised cylinder and piston
rod for corrosion resistance
` Low friction bearing surfaces
` Anti-extrusion seals for improved
performance at high pressures
` Overstroke restrictor port to prevent
over extension of piston
` Tommy bars for easy rotation of the load holding
lock ring are listed in the below table
` Saddle and piston rod details are
listed on pages 24 and 25
