700 Horepower. Mechanical Drive : Two engines with torque converters
Electric Drive : one DC traction motor

The 750 Series Drilling Rig has proven itself to be fast moving reliable rig of simple
and rugged construction. It is available in the following forms: A self propelled mechanical 
drive rig; a split trailer mechanical drive rig; a split trailer electric drive rig.

As a self propelled mechanical drive rig, the Model 2042 drawworks, telescoping mast, 
oil bath chain case elevated ratary drive and two engine rig power are unitized into one 
self propelled rig load.

As a split trailer mechanical drive rig, the drawworks and two engine rig power are mounted 
on one trailer and the telescoping mast and oil bath chain case elevated rotary drive are
mounted on a second trailer. The two trailer design accomplishes package weight control 
where permit limits may cause problems.

As an electric rig, an electric drive drawworks group has been developed using one 700 HP 
traction motor for both single and double drum drawworks and for the rotary drive. 
The drawworks, motor and hydraulic power unit are mounted in one self propelled package.

Both of the rig arrangements above are combined with a rig base and selection of single 
piece or multiple piece substractions to complete the rig. This rig in conjuction with single
load mud pump pacakages with independent power results in an extremely flexible arrangement.

Mechanical Drive Arrangement

Power - Two engines (any make) totaling upto 700 HP at 2100 RPM. The side-by-side 
engines are high mounted for easy accessibility and maintenance. Either or both engines 
can be used for hoisting, rotary or roading operations.

Torque Converters  - Two torque converters individually matched to engines provide 
maximum output power for single or two engine operation at full load or part load. Lockup 
feature in each converter for maximum efficiency.

Transmissions - Allision HT 750 DR,unitized with torque converters. Five forward speeds. 
Finger tip selection at driller's console with full load shift capability allows maximum flexibility 
of power application to job at hand.

Compound - v-Type roller chain compound in pressure lubricated oil bath case. Each engine 
can be disconnected in compound. Integral gear tranfer chase for vehicle drive.

Drawworks - Model 2042 drawworks with 19 5/8" diameter drum barrel 40" long. 12" x 42" 
circulating water cooled brake rims with full Wrap, single point adjusted, fully equalized brake 
bands. The easy access outboard drum cluch generates 40,000# single line pull. 
Paramac 202 single rotor brake assist with positive action clutch.

Catworks - Hydraulic catworks, including breakout cylinder, spinning and make-up cylinder
and planeatary gear, self-locking handling winch for smooth, safer catheading operations.

Drawworks Drive - Heavy-duty propeller shaft through Model 600 right-angle gear box.

Rotary Drive - Propeller shaft via full air rotary clutch, heavy duty reverse gear box and oil bath 
roller chain elevated rotary drive unitized on back face of mast. Simple propeller shaft connection 
at rig-up and rig-down. Nominal max. rotary speed-300 RPM.
Nominal working table torque - 30,000 ft. lbs.

Carrier - Mechanical drive rig provided with six axle triple front, triple rear 134,000# capacity 
carrier. Designed to meet highway safety standards with necessary toughness for off highway 
operations.

Electric Drive Arrangement
The 750E Series rig is designed as an SCR electric powered rig. One GE 761 (or equivalent)
700HP traction motor provides power to both the drawworks and the rotary. The drawworks 
drive is a two speed high/low drum clutch arrangement. An optional sand drum assembly may 
be mounted in the drawworks group. The rotary drive is taken from the drawworks drive via a 
Model 600 right angle gear box. The full air rotary clutch is mounted on a right angle drive 
output shaft. A propeller shaft drive and oil bath roller chain elevated drive mounted on the 
back face of the mast complete the rotary drive.

Features common to both mechanical and electrical drive
Mast - 112'300,000# API-rated telescoping mast. Dual ram hydraulically raised and extended.
Tubular construcion offering maximum rigidity and capability to withstand abuse. Patented pawl
mechanism assuring positive transfer of load from upper to lower section. Deep mast sections 
for maximum torsional stability. Heavy-duty rigid racking board with side-mounted fingers provided
 with finger safety locks. Load guylines to engine end of carrier.

Trailer - The mechanical drive and electrical drive arrangement of the 750 Series rig are both 
available as trailer type rigs or split rig arrangement. 

Substructure - Choice of T-Type telescoping substructure with derrick base and rig base or 
stacked fixed height substructure with setback cross base and derrick cross base. 15' high structure. 
Either type provides wind guy anchorage eliminating external wind guy anchors.

Hydraulic Power - 35 GPM 2500 psi max. pressure system. Provided by either of two pumps,
 one belt driven from front of each engine.

Power Reserve Line Pool  - On split trailer versions only  of the 750 Series rig, a hydraulic 
powered reserve line spool is provided on the mast trailer.
