The mast is normally used on land drilling rig types requiring a good deal of mobility; they are rarely used on offshore rigs. The racking board is in a cantilever position and lengths of drill pipeare racked on a floor, called the setback, that is separate from the mast structure. Most masts have one side open (window side),. .
There are different types of masts for land drilling and service rigs: 1. Folding Type 2. Telescopic Masts 3. Bootstrap Type 4. Portable/Cantilivered masts (Non-Guy line) .
Figure 8 shows a telescopic mast. Telescopic masts with their drawworks and engines are usually mounted on trucks or trailers. The load should be borne by hydraulic or. .
Each structure shall be rated for the following applicable loading conditions. The following ratings do not include any allowance for impact. Acceleration, impact, setback, and wind loads will reduce the rated static hook load capacity. Technical specifications are identical to those for derricks: 1. Maximum hook load given the reeving system, 2. F. .
For conventional Mast (Land rig), the below pictures show the erection sequence of rigging up For rigging up the vertical mast, the below pictures show the bootstrap sequence of rigging up.
[pdf] The ultra-short mast drill rig is a version of our machines with “reversed” kinematics, allowing the contractor to drill under 20ft of over headroom to a depth of 60ft, with a 10ft tool in front of the mast. A unique machine that can't be matched in the market.
