APPLICATIONS

FEATURES

Excessive clamp force caused by too much hydraulic pressure
is one of the most common causes of damage to paper rolls.
Mechanical 3-position relief valves are under-utilized or
primarily left on the high setting. HFC (Hydraulic Force Control)
solves these issues by automatically adjusting clamp force.
HFC is a hydraulically controlled automatic clamp force system
that changes the clamp force proportional to the load weight. It
works by continually sensing the hydraulic pressure necessary
to lift the load and adjusts clamping pressure as the weight of
the load increases or decreases. The system operates without
any special actions on the part of the driver.

■

Conveniently sized hydraulic valves mount easily onto the
cowl of lift truck.

■

Innite adjustment of clamp force in the capacity range
of the attachment. The system adjusts clamp force
proportional to the roll weight.

■

When installed with the equalizing valve, the clamp
force remains constant between Freelift and Mainlift.
Accomplished with the use of a switch that determines if
the clamp is in Freelift or Mainlift.

■

HFC is exible, allowing easy adjustment for:
• All clamp force settings
• Maximum pressure
• Balancing clamp force between Freelift and Mainlift
• Balancing clamp force when the size of the truck and
clamp are not ideally matched.

■

Compatible with Split and Solid Arm Clamps.

BENEFITS
■

No need to change driver habits.

■

Driver can use normal operating procedure: Close clamp
arms on load and then hoist load off ground.

■

Hydraulics can be feathered to allow driver to control clamp
force on extremely small, light loads.

■

Quick Installation only requires tapping into the Hoist,
Clamp and Open lines.

■

Low maintenance system does not require an accumulator
to charge the system (which can lose charge).
