TXD

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

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
