Hydraulic
Safety Restraint Cylinder / Manifold System:
Model #: HRA-1000-AP (Allsteel & Piranha Brakes)
Hydraulic Safety Restraint Cylinder/Manifold System Description:
The HRA-1000-AP was designed and developed for the purpose of
bringing hydraulic presses equipped with one (1) cylinder to the
CSA-Z142-02 and ANSI standards for mechanical and hydraulic presses.
It incorporates a custom designed manifold that is attached to
a hydraulic cylinder and is equipped with two (2) monitored safety
valves that can lock and prevent the initiation of the press as
well as the free fall of the ram should the main cylinder fail.
One manifold assembly is potentially needed per side.
Detailed
Features
- Incorporates
valving required to safely support the Press Brake platen.
- Complies
to the Canadian Z142-02 code for Power Press Operation for hydraulic
presses and US ANSI/OSHA B11.2-1995(R2000)
- All ports
will be SAE O-ring ports, no NPT ports on manifold or cylinder.
- Attaches
directly to the hydraulic restraint cylinder's ports.
- Two (2)
HRA-1000-AP assemblies are required per Press Brake.
- The HRA-1000-AP
assembly is static and dynamically tested prior to installation.
- Smaller
single cylinder utility presses can be retrofitted with one
HRD-1000-AP

The Hydraulic
Safety Restraint Cylinder/Manifold (HRA-1000-AP) is an engineered
product, designed to work in conjunction with the BrakeMizer BMZ-1000-HRA
or it can be controlled by a safety PLC.
Key Benefits:
- Self-contained
manifolds with direct coupled cylinders.
- The manifold
is independent of the press.
- Easy installation
means minimized down-time and no extensive piping required.
- Meets or
exceeds the Z142-02 and Z432 04 requirements for ram arrest
on a hydraulic press.
- Restrains
ram under stop and fault conditions.
- Fewer manifolds
used than competive systems.
- Non-invasive
installation.
- Installs
within one (1) day on most presses (not including installation
of controls).
- A minimal
amount of hosing required for connection.
- Minimized
leak potential.
- Systems
can be easily removed and transferred should asset be sold.
- Systems
are factory pre-set and require no on-site calibrations.
- Built-in
control for ram drop prevention during upstroke via check valve.
Hydraulic
Safety / Manifold System: HRA-1000
Suitable
for Dual Cylinder Down-Acting and single or multiple cylinder
up-acting Brakes.
 Detailed
Features
- Incorporates
valving required to safely support the Press Brake platen.
- Complies
to the Canadian Z142-02 code for Power Press Operation for hydraulic
presses and US ANSI/OSHA B11.2-1995(R2000).
- Attaches
directly into the existing hydraulic system.
- One (1)
or Two (2) assemblies are required depending upon the machine's
design.
- The HRA-1000
assembly is static and dynamically tested prior to shipping.
