GMP G Lasher
Lashing wire magazines & capacities
The lasher has two magazines for loading of lashing wire;
each can hold a coil of .065 in. x 450 ft. (1.65 mm x 137 m)
wire. Note: .045 in. x 1200 ft. (1.1mm x 365 m) coils may
be used as an alternate. Each magazine has two rollers for
guiding and tensioning wire during lashing. The wire coils
are held stationary in the magazines, with the wire feeding
from the center of the coil eye through a throated hole and
over a guiding roller; it is then threaded around the rollers
and wound onto the cable/strand bundle.
Your lasher can use a single wire or two wires simultane-
ously (often called “double-lashing”) wherever extra
strength is desired. Unlike other machines, the balance of
a GMP lasher is not adversely affected by the amount of
wire loaded in either magazine.
There are two rubber strand drive wheels mounted in the
forward part of the machine in the drive housing and
geared directly to the rotatable drum. A smaller trailer
wheel located in the rear of the carriage supports the rear
end of the lasher on the strand. Maximum traction is pro-
vided by forcing the strand into the groove of the two rub-
ber drive wheels by means of a tensioning device actuated
through a system of levers. This feature provides uniform
traction regardless of the angle between the pulling line
and the strand.
Adjustable rear gates & cable lifter
The rear cable lifter rollers are adjustable vertically to
accommodate cables of various diameters and are held in
the open position by a spring catch on each side. To open
the rear cable lifter loosen the bottom knurled knob suffi-
ciently to swing free. Swing both gates open until the
spring catches are engaged. DO NOT force the gates open
past the point of engagement of the spring catches to
avoid deforming the springs.
To adjust the rear cable lifter, open the rear cable lifter,
and loosen the bottom knurled knob sufficiently to swing
free. Raise or lower the cable lifter rollers on each side by
turning the knurled knobs at the top of each vertical
adjusting screw until the desired height is obtained.
Observe that the rollers are in proper alignment and swing
the bottom knurled knob up into the closed position and
tighten securely.

Placing the lasher on the strand
1. Open the rear cable lifter, adjust it to its lowest
position and close it.
2. The strand tensioning roller assembly should be in the
open position, placed against the side of the aluminum
housing. This is done by depressing the lever projecting
up through top of cover of gear unit and turning it
clockwise to the open position.
3. Attach a handline to the strand and to the lasher
handle and raise the lasher to the strand by means
of the handline.
4. With the machine at the required height, open the rear
cable lifter past the spring lock and place the lasher on
the strand. Also, attach one of the snap hooks on the
lasher tow bridle (rope) to a pulling eye and the other
hook to the strand as a tether.
5. Engage the strand tension roller assembly by pressing
the lever all the way down and turning it counterclock-
wise, allowing it to rise. When the strand tension roller
assembly is in the engaged position, the end of its sup-
porting casting is engaged in the grooved guide on the
inside of the gear housing.
6. Raise the cable to the strand (by hand), close
rear cable lifter and let the cable rest on the rollers.
Estimate the amount the rollers should be raised
to elevate the cable to within 1⁄4 in. (6 mm) of the
strand. Lift the cable slightly (by hand), open the
cable lifter, lower the cable clear of the opening and
turn the adjusting knobs on top of the threaded posts
until the lifter is raised the desired amount. Raise the
cable (by hand) and close the lifter.
