Introduction

The ParKlamp system is designed for restraining tube, pipe and

hose assemblies against unwanted and potentially harmful ef-

fects of mechanical shock and vibration forces that are common

in fluid power systems.

The clamping system is the most commonly overlooked aspect

of fluid power system design. Failure to properly restrain the

fluid conductors can result in leakage, downtime and system

malfunction, as well as significantly reduce the life of tube, pipe

and hose assemblies. With the ParKlamp system, the risk of

problems resulting from mechanical shock and vibration can

be significantly reduced.

Design and Construction

Designed to meet the basic envelope dimensions of DIN 3015,

Part 1, theParKlampplasticclamphalvesare interchangeablewith

theParker metric clamp system.The primary difference between

these two clamping systems is the utilization of inch, as opposed

to metric, thread hardware in the ParKlamp system. All plastic

clamp halves in the ParKlamp system are manufactured from

Polypropylene material. The hardware portion of the ParKlamp

system is available in plated steel and stainless steel.

For convenience, the ParKlamp system is divided into three

different series: Standard, Heavy and Twin. Each series has

correspondingcomponents, physical dimensionsandmechanical

properties. Within each series, there are a number of groups,

each with specific envelope dimensions. Components from

different series and/or groups can not be intermixed. However,

the standard and twin series can be mounting on the same

mounting rail.

How It Works

The ParKlamp system has two primary methods for mounting:

weld plates and mounting rails.

Clamps should bemounted to a rigid structure for optimum

performance. Clamping tube, pipe or hose assemblies

together without mounting them to a rigid structure, often

called “floating clamps,” does not provide adequate sup-

port.

Proper design of a clamping system requires that the

clamps be positioned appropriately on the tube, pipe or

hose assemblies. See th

Weld Plate Mountin

g

(Fig. P1)

The weld plate mounting system allows the user to attach a

single clamp assembly to a structure of similar material (steel

to steel, etc) by welding the components together. Once the

weld plate is attached to a structure, one clamp halve can be

placed onto the weld plate, followed by the tube, pipe or hose

assembly. Next, the second plastic clamp halve can be placed

on the tube, pipe or hose assembly, followed by the cover plate

(or Insert).To complete the assembly, the Hex Head attachment

bolts are inserted into the assembly and tightened to the torque

shown in the Assembly section of this catalog.

Mounting Rail Mounting

(Fig. P2)

Use of a mounting rail is another way to assemble the clamping

system components onto a support structure. Using a mounting

rail allowsmultipleclamps tobemountedside-by-side for restrain-

ing a group of tube, pipe, or hose assemblies.The mounting rail

also provides the ability to move the location of the clamps in

one direction for easier alignment. The rail can be attached to

a support structure by welding or bolting. Once the mounting

rail is in place, rail nuts can be slid into the rail. The first clamp

halve, followed by the tube, pipe or hose assembly, can then be

installed over the corresponding rail nuts. After this, the second

clamp half, the cover plate (or Insert) and the hex head attach-

ment bolts can be installed to complete the assembly.

Stackin

g

(

Fig. P3

)

A primary feature of the ParKlamp system is its ability to ac-

commodate stacking of a series of clamps to various heights,

thus requiring a smaller footprint for mounting.To do this, simply

use the stacking bolts to mount the first clamp assembly, then

install a stacking plate over the first clamp and stacking bolts.

The second clamp assembly can then be placed over the first

clamp assembly.Complete themounting by assembling a cover

plate and using the hex head bolts to tighten the upper clamp

assembly.

Note: When stacking, the clamps must be from

the same series and group.
