GENERAL DESCRIPTION
The Gullco "Kamel", power turning rolls are electrically powered units that use wheels to rotate (roll)
pipe. They are designed to be used in conjunction with a non-powered idler roll / rolls. Each of the
wheels of the turning, and idler, rolls have a moulded rubber tread and rotate on anti-friction roller
bearings. The turning roll uses these wheels to provide friction drive and uniformly smooth pipe
rotation, while the idler roll / rolls use these wheels to support the pipe.
The powered turning roll imparts tractive effort to the wheels by having a knurled drive wheel press
against each of the rubber wheels. This knurled drive wheel is directly attached to the output shaft
of a 24 VDC, permanent magnet motor and gear head power unit assembly. The microprocessor
motor control offers operator interface of forward, stop, reverse and infinitely variable control of the
speed, within the range of the model. Safety is greatly enhanced by the use of Gullco’s low voltage
(24 V), control and power supply system that is available in one of the following three line voltage
inputs: 42, 115 and 230 VAC, single phase, 50/60 Hz, or any unregulated 24 VDC power supply at
220 watts of power. The motor control offers operator interface of run/stop, clockwise, neutral and
counter-clockwise rotation as well as speed regulation. A power supply on/off isolation switch is
also provided. The rotation speed is electronically controlled using an optical tachometer located
on the back of the gear-motor and is infinitely variable in both clockwise and counter-clockwise
directions, within the range of the model, by a rotary speed adjustment potentiometer located on the
faceplate of the "Kamel" power roll. The powered turning roll is also equipped with a 7-1/2 foot [2.3
mtr.] long power cable and a remote foot switch on 10 feet [3 mtr.] of cable. A lifting handle is also
provided for portability.
INTENDED / FORESEEN USAGE
Gullco "Kamel" turning rolls are widely applied to reduce the cost of welding and cutting pipes,
flanges and fittings. They are compact, portable and provide fast positioning and smooth rotation.
The power turning roll requires at least one or more idler rolls to support the work piece. Both the
power and idler roll are designed to support 750 Lbs. [340 Kg.]. Therefore, by using one powered
turning roll and one idler roll a maximum weight of 1500 Lbs. [680 Kg.] is capable of being
supported.
Through automation / semi automation, the quality, efficiency and repeatability of the weld or cut
produced is greatly improved. Detrimental factors such as poor or awkward accessibility, operator
fatigue, or inconsistent workmanship are eliminated. Required quality levels are consistently
attained and productivity and profitability increased.
