1500hp Basic Drilling Rig - 152ft x 25ft 770,000lbs

One (1) Full Circle-on-the-floor cantilever beam leg drilling mast with a maximum clear height of 152’-0” x 25’-0” wide base and a rated static hook load of 770,000# on ten (10) lines strung to the traveling block per API 4F specifications.  Mast is designed for 80 mph wind load with a full rack of pipe and 105 mph on a bare mast.  Mast stem portal truss designed affording excellent driller’s view and is complete with raising sheaves and A-frames.  Mast has full height straight ladder drill floor to crown and includes the following additional equipment:
One (1) slingline equalizer unit
One (1) set each front and rear shoes.
One (1) set of four (4) standpipe clamps for double 5” standpipe.
One (1) Full Circle flat-running crown block with six (6) 50” minimum diameter cluster sheaves and one (1) 60” minimum diameter fastline assembly, all with tapered roller bearings and grooved for 1-3/8” diameter wireline.   Cluster sheaves are mounted on a crown frame so flat face of traveling block faces derrickman.  Crown frame includes wireline guards, bumper blocks and pad eyes for hanging, catline and air hoist sheaves.  Includes crown safety platform for crown service with 3’-6” high with zerks located handrails and expanded metal flooring.  Each sheave is lubricated by individual grease channels on one end of the shaft.
One (1) Full Circle heavy-duty racking platform with a capacity for 15,000 ft. of 5” drill pipe, four (4) stands of 10” drill collars and ten (10) stands of 8” drill collars.  Platform is complete with folding diving board, access catwalk and fold-up floor slab for driller’s side.  Platform is adjustable from 82’-0” to 87’-0” above drill floor and includes 3’-6” high handrails.
Two (2) air hoist sheave units – 14” OD steel sheave grooved for 5/8” diameter wireline and mounted on roller bearings.
Two (2) counterweight systems with buckets, guides, tracks, load lines and 8” snatch block

One (1) hydraulically raised substructure configured to support the above on floor mast, with a nominal base dimension at the mast shoes of 25’-0” and a static hook load of 770,000#.
The substructure is designed to allow for installing of the mast on the drill floor while the substructure is in the low position and raising the mast to its working position prior to raising the substructure.
Includes a parallelogram type, raising system powered by two (2) hydraulic winches operating two(2) sets of six (6) part raising lines, one (1) hydraulic power unit complete with remote control panel, gauges, hoses and fittings and two (2) hydraulic break-over rams.
All critical load-carrying members are fabricated form hi-strength steel (w/min. yield strength of 50 ksi).
All fabrication procedures/welding is performed in accordance with API 4F specifications incorporating AWS and AISC recommendations.
Nominal Dimensions:
Width: 31’ - 2 1/2 “
Height: 30’
Length: 54’
