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, form-

ing 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 Phila-

delphia 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.

The Pulldog winch is a compact, transportable unit for any

number of outside plant activities that’s easily pulled behind

a small SUV or truck. The self-contained winch is powered

by an 11.7 hp gasoline engine and the precise control

required is provided by the hydraulic circuit.

The Honda GX390 engine drives a fixed displacement

pump, which in turn drives a fixed displacement high torque

motor. The circuit is controlled by a spring centered

hydraulic valve, which provides selective direction of drum

rotation. The lever acts as a dead mans handle in that letting

go stops everything in a safe mode. The circuit design also

includes the ability to provide inching or very slow speed control in both directions under tension, ideal

for overhead line use.

The sturdy steel construction chassis is equipped with manually operated stabilizing props to assist

when pulling.

The Pulldog Winch is designed to meet the needs of overhead line engineers. The various options permit

use on aerial bundle (ABC), Copper, Aluminum and ACSR Conductors.

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 (KT), LLC CANNOT BE HELD RESPONSIBLE FOR MIS-USE OF THIS

EQUIPMENT.

To enable safe and trouble free operation the following points should be followed.

Prior to employing the winch for any hauling applications it is important to ensure that the winch is suita-

bly anchored to a Vehicle.

5.1 Ensure that the ball coupling and the center of the drum width is

oriented with the line of pull. See Fig 5.1. This ensures that reeling

of the rope takes place without undue pressure on the layering de-

vice and extends rope life.

5.2 Vehicle Anchoring - Preferred method of anchoring

Align the winch as in 5.1 keeping the ball coupling securely attached

to the vehicle. Lower the rear prop legs and lift winch weight off

wheels onto legs and fix. Ensure winch is level from side to side.

5.3 Ground Rod Anchoring (if vehicle anchoring is not obtainable)

Lower the rear prop legs and front prop to the ground, such that the winch is level from side to side and

the weight is off the wheels. Drive a ground anchor through each chassis anchor bracket at the tow eye

end of the chassis, See Fig 5.3A, The quality of the ground needs to be assessed with regards suitability

for winch anchoring prior to winch operation.

5.4 Loading/Unloading drums

To load/unload a drum it is necessary to remove the rear spool guard. This

should be stored in a suitable place and re-fitted when the trailer is to be

used in transit again. Open the split bearing and slide the drum to the right.

Lift the drum vertically initially favoring the side with the split bearing. Re-

verse to install.

Remove pins and remove spool guard Open split bearing Slide drum out of coupling Remove drum

5.5 Pulling Out Winch Line

Place the drum free wheel mode by disengaging the coupling and the winch

line can be simply pulled out as required.

5.6 Starting Engine

The engine fuel tank should be filled with the correct grade of fuel before

commencing, refer to the Engine Operating Manual for details. Switch the ig-

nition, switch it ‘ON’. Turn on the choke, set the throttle to half and pull starting handle in a long steady

stroke to start. For further details refer to the Engine Operating Manual.

5.7 Driving Drum

Rotate the drum until the couplings on drum and motor align

and slide drum towards motor, and then rotate drum to ensure

the drum is engaged.

With engine running the control valve can now be engaged.

Pulling the handle back wards towards the towing eye will com-

mence drum rotation, pulling the rope in. The handle controls

direction and speed. Pushing handle toward reverses direction

of rotation.

5.8 Layering Device

The arrangement fits to the side arm with the motor mounted

on, and is secured with a ‘R’ clip. The layering device is used to assist layering of the winch line. Careful

setting of the equipment will prevent excessive forces on the layering device. Always wear protective

gloves when operating the layering arm.

The layering arm MUST NOT be used for conductor recovery.

5.9 Holding Ratchet

This device is fitted to the drum drive coupling and should be kept in the

open position (i.e. non operational). The holding ratchet should only be

used after pulling through heavy conductor when winching has stopped

and conductor is held ready for sagging.

To remove holding ratchet after engaging, it is necessary to start the winch

and pull further to remove load, prior to removal of ratchet.
