About Hydraulic Backstay Adjusters
Harken Adds Two Sizes to Double-Acting Hydraulic Backstay Adjuster
has added two larger sizes to its line of Integral Hydraulic Backstay Adjusters.
These additions to Harken's other two sizes have expanded the range to accommodate
boats with wires from 5.5 to 9.5 mm (7/32 to 3/8 in) approximately 9-18
m (30-60 ft). In an industry first, the cylinder features an integrated
double-acting pump that delivers oil when the handle is pushed and pulled,
reducing pumping time by nearly doubling the flow of single-acting pumps
standard on other integrals.
“Creative engineering and design allowed Harken to greatly improve
our integrals over other systems out there,”said Harken Hydraulics
Manager Robbie Young. “Our double-acting pumps deliver oil twice
as fast as single-acting pumps which are standard on other integrals.”
Other key concepts:
The pressure release has been reconfigured, making it impossible for crew
to over-tighten the screw by hand and damage the valve when closing it
for pumping-a common problem on other cylinders.
A gauge with an easy-to-read analog display mounts at the top-not the
bottom-of the cylinder for easy viewing from the cockpit. Pressure relief
is factory set to prevent crew from over-tensioning the backstay.
Cylinders come standard in four sizes with a clevis on both ends. Assemblies
include a hardcoat-anodized aluminum cylinder and pump, valve, gauge,
and stainless pump handle with three attachment options. All pins and
plugs are stainless steel. Clear-anodized aluminum cylinders are available
