Safe Working Load Rating:
500,000 lbs (250 Tons) 450,000lbs below hook
1. Built to API Spec 4F Specification for Drilling and Well Servicing Structures
2. Canadian Drill Rig Standard
Stabilization:
1. Two struts between the Derrick and the trailer are the safety supports on the
back side of the Derrick.
2. Trailer has 4 jacks – 2 at the rear of the trailer and 2 toward the gooseneck
transition. There are 4 non-hydraulic screw jacks permanently welded into the
trailer – 2 at the tilt cylinder attachment point and 2 at the rear of the trailer to
handle half of the drilling forces. 2 additional screw jacks are on the substructure
beam that carries the other half of the drilling forces.
3. Drill Rig mounted on Triple-axle trailer, air ride suspension. Comes with a Tandem Stinger axle for
Transportation on roads.
4. 10’Max Overall Transport Width
5. The trailer jacks raise the rig enough to provide about 8’ of clearance below the drilling floor.
Derrick:
1. Space Frame construction made mostly of plate having triangulated lightening
holes where possible. The design will not require a truss for stiffness.
2. Removable 15ft rear section allows shorter transport length.
3. Designed to operate only in the vertical position
4. Range III drill pipe compatible length
5. 50’ of total carriage travel.
6. Ladder – full length with harness attachments.
7. 2 Telescopic cylinders are used to raise the Derrick. Load check valves are
integrated into the cylinders. A third cylinder (single stage) has a cable attached to
the rod end and controls the Derrick when it is nearly vertical. It will prevent
the telescopic cylinders from undergoing an overrunning load.
8. 2 winches are provided at the top of the Derrick
Drill Pipe Handling System:
1. Swing arm type of handling apparatus with opposed jaw grippers that roll 180 degrees.
2. Alignment is by patent pending American Augers floating assembly which ensures reliable
alignment of pipe.
3. The pipe handler is powered by the rig.
4. The controls are electric over hydraulic with sufficient cabling to operate from the driller’s cabin
5. Suitable for 2 7/8” drill pipe to 8” collars & 9 5/8 casing – max load 3500lbs.
Drilling Floor and Support Beam:
1. Drilling structure has a steel floor covered in Hi-Vis Anti Skid plastic Trac Mat
A slip bowl attaches to floor
2. The rear of the trailer and drilling floor is supported by a deep beam that attaches
to the back of the trailer structure. The beam has screw jacks at each end which
conduct the load against 6’ x 6’ ground platforms.
3. (14’) of approximate vertical clearance from the ground to the bottom of the drilling floor.
4. The drilling floor is 1⁄4” diamond plate and is supported by tubular braces that are pinned in place.
5. The slip assembly is hydraulically powered and is controlled from the cabin.
Carriage:
1. Rack and pinion carriage drive - Six (6) pinion
2. 500,000 lbs. @ 44 FPM in max pull mode
