Mounting Rail Mounting

(Fig. Q2)

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

half, 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 and the hex head attachment bolts

can be installed to complete the assembly.

)

A primary feature of the Metric Clamp system is its ability to

accommodate 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.

Introduction

TheParkerMetricClamp system is designed for restraining tube,

pipe and hose assemblies against unwanted, and potentially

harmful effects 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 systemdesign.Failure to properly restrain the fluid

conducting system can result in leakage, downtime and system

malfunction, as well as significantly reduced life of tube, pipe

and hose assemblies.With the Parker Metric Clamp 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, the plastic clamp halves are interchangeable with the

ParKlamp system. The primary difference between these two

clamping systems is the utilization of inch thread hardware in

the Parklamp system, while the Metric Clamp system utilizes

metric hardware.

For convenience, the Metric Clamp 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 mounted on the same

mounted rail.

How It Works

The Metric Clamp system has two primary methods for mount-

ing: weld plates and mounting rails. Clamps may be mounted

to secure a single layer of tube or stacked for securing multiple

layers.

Clamps should be mounted 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 support.

Proper design of a clamping system requires that the clamps be

positioned appropriately on the tube, pipe or hose assemblies.

Weld Plate Mounting

(Fig. Q1)

Theweldplatemountingsystemallows theuser toattachasingle

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 half can be placed onto the

weld plate, followed by the tube, pipe or hose assembly. Next,

the second plastic clamp half can be placed on the tube, pipe

or hose assembly, followed by the cover plate. To complete the

assembly, the Hex Head attachment bolts are inserted into the

assembly and tightened.
