1.0 INTRODUCTION

Founded by engineer George M. Pfundt in 1936, GMP started operations in a
downtown Philadelphia building as a specialty machine shop doing work for the
local Bell Telephone company and for the electric utility company. GMP expanded
to a production shop after landing a contract
with Western Electric Company and,

subsequently, forming a close relationship
with Bell Telephone Laboratories in Murray Hill, N.J., which enabled
it to manufacture prototypes of products for experimental use within
the Bell System.

Having outgrown the original factory building, the company built a
100,000 square foot plant in Trevose, PA (a Philadelphia suburb)
and moved there in 1957. Today GMP is recognized as a premier
worldwide supplier of specialty tools and equipment for the outside
plant marketplace. The company's products are known for their
robust design and durability to withstand many years of frequent use.

following precautions to avoid hydraulic hazards:-

1. Tighten, secure all connections before applying pressure. Relieve pressure when connecting or

disconnecting hoses when servicing the unit.

2. Check for leaks with a piece of cardboard. Do not use your hands!

3. Do not exceed working pressure of hydraulic hoses.

4. Visually inspect hoses regularly and replace if damaged.

3.0 GENERAL DESCRIPTION

C-1350 CABLE PUSHER

The machine comprises of an hydraulically driven cable pusher unit designed to provide an effective and
safe method of installing 1 1/4 - 6” (30 –150mm) Dia. cable up to a speed of 33 ft/min (10 m/min).
The pusher unit is mounted on a sturdy anti corrosion treated tubular steel frame and is powered by a
hydraulic supply system operating from a recommended supply of 870 psi (60 bar) x 4.75 gpm (18 litres/
min).

The cable pusher is fitted with adjustable vertical rollers at each end to guide the cable through the
machine.

2 x hydraulic hoses x 23’ (7m) long can be supplied as an optional extra.

FEATURES
CABLE FEEDER

• Manufactured from fabricated and machined steel

• Hydraulically powered

• Unit lifts and splits to allow insertion of cable between drive chain and roller.

• Drive chain has, optimised profile and moulded to chain drive unit ensuring long life between

replacement..

• Belt tension can be set by means of adjustable chain drive tensioner fitted to side of unit.

5.0 OPERATING PROCEDURE

IT IS IMPERATIVE THAT ALL PERSONS USING, OPERATING OR MAINTAINING THIS
WINCH BE FULLY TRAINED AND COMPETENT TO DO SO, AND HAVE READ THE
ENTIRE OPERATING MANUAL.

GENERAL MACHINE PRODUCTS CANNOT BE HELD RESPONSIBLE FOR MIS-USE
OF THIS EQUIPMENT.

• Position the cable pusher at the desired angle for entry into the joint box, ideally this should be on
firm level ground.

• Ensure that the cable pusher is adequately anchored down / restrained.

• Raise the upper roller assembly by removing 2 retaining pins from one side and pivot roller

assembly out of the way.

• For large diameter cables it may be advantageous to remove 2 vertical end rollers from the same
side as of the machine as the removed retaining pins.

• Cable can now be laid onto drive chain.

• Replace vertical end rollers, (if removed to allow easy access to insert the cable) and adjust to give a

5mm clearance each side of the cable.

• Ensure the upper rollers are positioned at the top position of their travel.

• Pivot the upper roller assembly back to the operating position, ensure that the best hole position to

suit the size of the cable is selected and refit the 2 retaining pins.

• Lower the two sets of rollers in conjunction by tightening the main jacking screws until contact
is made with the cable, then turn the jacking screw a further 1½ turns.

• Connect the hydraulic hoses from the hydraulic power pack and suitable control valve via the quick
release couplings..

• Start the power pack and operate the hydraulic control lever to commence the cable feed
operation, NOTE the power pack operator must be competent and fully trained in the use of
the power pack.

6.0 MAINTENANCE

To ensure reliable service from the Cable Pusher, GMP recommends the unit to be completely serviced at
6 monthly intervals.

TRACTOR DRIVE

Inspect the chain drive blocks for wear. Clean all drive blocks after each operation or as required. (it may
be necessary to remove the upper roller frame assembly to clean thoroughly). Check the chain tension
weekly and adjust if necessary with the two external adjustment screws. (Do not over tension – the chain
should just slightly lift of the chain guides when pulled at the centre by finger).

GENERAL

The machine should be wiped clean after use and stored under cover.
Oil the frame pivot points monthly and apply grease to the jacking screw thread. After each use clean off

any dirt/debris from the cable guide rollers and upper frame rollers.
The chain should be lubricated every week by application of Metaflux Spray Grease 70-07. This is achieved

by running the unit (without any cable.
Do not over lubricate as this may lead to contamination of the drive belts. Should contamination of the belts
occur, wipe the belts thoroughly clean before attempting any cable pushing operation.

Check the condition of the hydraulic hoses each time and replace if worn or damaged.

6.1 MAINTENANCE SCHEDULE

PROCEDURE DAILY WEEKLY MONTHLY

Clean all assemblies and components thoroughly
Inspect hydraulic hoses for leaks and cracks
Inspect fasteners, screws and retaining pins/wires
Check/Adjust chain tension
Check tractor drive pads for wear/damage
Clean cable entry bracket
il the frame pivot points
Grease jacking screw thread
Oil oilite bearings with light machine oil
