  2. TXD Design Goals • Alternative to a “Big-Rig” • Shallow oil/gas and CBM applications • Handle range 3 casing • Quick and easy set-up and breakdown • High performance in compact package • Low axle weights • Automated pipe handling • Hands free breakout (hydraulic roughneck) • Powerful tophead rotation system

  3. Telemast Concept Innovative design offers 2:1 cylinder/head travel Head fully retracted for short transport length Mast fully extended as required for setting casing Construction locates cylinder rods out of harms way Mast slides so loads are transmitted to the ground Mast mounted hydraulic outriggers support loads High tophead travel speeds

  4. Basic Specifications Mounting: Custom tri-axle trailer with tag dolly Deck Engine: MTU 12V-2000, 760 hp, air starter Tophead: 4 3/4” ID (120.6 mm) spindle, 4 x two speed motors, 0-90 rpm @ 17,750 ft-lb, 0-180 rpm @ 7,670 ft-lbs Mast: 50’ top head travel, 30 1/4” table, power holding slips Fluid Lines: 3” ID, 3000 psi WP Feed System: 200,000 lb (actual) hoist, 32,000 lb. down Pipe Handling Winch: 9,600 lb with hydraulic jib boom Automated Pipe Handling System: Custom tandem axle trailer powered by rig hydraulics, up to 47’ long x 30” OD tubulars Power Breakout: Hands free, 4½” to 8” OD, 53,000 ft-lb

  5. Basic Dimensions • Minimum Overall Length: 50’ (15.2 m) • Front Overhang: negligible • Width: 9’ 6” (2.9 m) • Height: 13’ 6” (4.1 m) • Weight: 95,000 lb (43,181 kg) • Distribution: 20,000 lb/axle (9,072 kg), 17,000 lb/axle (7,711 kg) with tag dolly

  6. Tilt-out Top Head0-90 rpm @ 17,750 ft-lb, 0-180 rpm @ 7,670 ft-lb Single reduction spur gear drive Large tapered roller bearings, no pinion bearings required Four, 2 speed, high torque hydraulic motors 4 ¾” ID thru shaft Floating sub Casing lifting eyes
