Read me
first!

This manual covers the care, operation and maintenance
of your GMP model G Cable Lasher, which you can use to
lash cables from about 2

1

⁄

2 in. up to 5 in. (125 mm) dia. to

suspension strand, or smaller cable sizes to an existing
lashed cable and strand (a process called “over-lashing”).

This machine is intended for use ONLY by properly trained
journey linespeople or other craftspeople under the DIRECT
supervision and responsibility of those individuals.

As such, this manual’s scope is specifically limited to
the machine’s functions, and no attempt is made to
describe the proper procedure for placing and lashing
aerial cable plant.

We cannot be held liable for any direct or indirect con­sequences arising from use of the product by any indi­viduals not already properly trained in its use.

If you would like information about professional training
programs, call us for details.

Important
precautions

The proposed cable run should be pre-surveyed to deter­mine the terrain and field conditions that will be encoun­tered in the lashing operation. Among those factors to be
considered (not by limitation) are:

(a) vehicle & pedestrian safety
(b) condition of poles, anchors, guys and strand
(c) proper bonding and grounding of strand

and attachments

(d) obstructions such as trees, limbs and

drop wires

(e) clearances and separations on poles shared by

other utilities

(f) clearances over roads, driveways, walkways

and crossings

Protect your work site with advance warning devices at
strategic points to warn traffic and pedestrians of the
obstruction in the area.

Check your machine first!

Prior to using the machine, check that it is in good repair,
that all of the parts and mechanical assemblies are intact
and in good working order. If the machine has not been
properly maintained it may well be unsafe to use and pose
unnecessary risk to the user. GMP Lashers can be profes­sionally repaired and/or overhauled at the factory with
quick turnaround and minimal downtime.

Use the proper safety equipment!

Before working aloft, inspect all your climbing and safety
equipment to make certain it is in good repair. And while
you are aloft, ALWAYS wear a body belt with a safety
strap securely attached to help prevent you from falling.

Also, you should always raise and lower your lasher only
with a proper aerial handline (such as our 68590 or

08192) or a truck lift.

Use the bridle assembly at pole transfers!

When transferring the lasher around a pole or other
obstruction, use the bridle assembly as a tether to prevent
damage to the machine in case it is dropped. This also
allows you to concentrate on your own safety first rather
than the safety of the machine.

About your
G Lasher

Look at your G Lasher for a moment. You will see it
consists of a rotating drum supported on a carriage; the
strand and cable pass through this carriage during the
lashing operation.

As you look at the carriage, you will see it also has a
forward direct gear drive mechanism, cable and strand
rollers, front and rear gates, various pulling eyes and an
anti-backroll brake.

The major components are made of heat-treated, high­strength aluminum alloy, bronze, stainless or zinc-plated
steel. Sealed aircraft-type, dust-proof ball bearings are on
all shafts and the drum, with other moving parts mounted
on Oilite bushings.

At about 71 lbs. (32 kgs) without wire, your machine’s
weight and features give it an optimal strength-to-weight
ratio for the heavy-duty work of lashing large telephone
cable(s) or electrical distribution cables.

Cable capacities

The G Cable Lasher can be used for securing aerial cable
from about 2

1

⁄

2

in. up to 5 in. (65 - 125 mm) diameter to

suspension strands from

3

⁄

8 in. to

3

⁄

4 in. (9 -19 mm) diame-

ter with a spiral lashing of .065 in. (1.65 mm) stainless
steel lashing wire. (A modification for .045 in. / 1.1 mm
stainless steel wire is also available.) The G Lasher has
the capability of lashing any number of cables to a single
suspension strand provided that the entire diameter of the
cable bundle not exceed 5 in. (125 mm).
