Description of the caliper
1.1 Principle
The HW 165 FHM calipers are hydraulic fail-safe calipers; the braking force is applied by spring
washers and hydraulic pressure is necessary to hold the brake released. The stack of spring
washers is adjusted in factory. This adjustment, combined with adjustment of the pads gap,
determines the braking torque value.
There is a type plate on the brake with a 16-digit article number. The exact design of the brake is
defined by this article number only.
As well as these instructions, please also consider the catalogue data for the brake at
www.ringspann.com and the drawings in the individual sections.
The
Caliper is describe as “manually readjusted”. This means that the pad wear must be
compensated for by manual adjustment of the pad gap to avoid any loss of braking force.
The brakes have a manual release device mechanically holding the caliper open, without any
need for a hydraulic pressure. This release is useful for installation and maintenance work when
there is no hydraulic pressure available.
1.2 Delivery condition
The caliper is delivered in the following conditions:
- With two breaking pin Ø46g6,
- In manual release position, i.e. manually locked in open position,
- With pads installed,
- Adjusted with the nominal lining gap,
-
The holding force adjusted according to customer’s specifications,
- Mechanical contacts adjusted,
- With bleed screw in correct position.
- As well as these instructions, please also consider the catalogue data for the brake at
www.RINGSPANN.de and the drawings in the individual sections.
Important!
Be careful: Check the support thickness is E+ 30mm
