Drilling rig spare parts Mast

Major features of “K” type mast:

1 Section type: “ K ” type , i.e. front opening.

2 Lifting and lowering down mode: integral.

3 Low position installations. Generally it has 4 ~ 5 sections for the mast; flatly contacts between sections and bi-taper pin fixation are used for ensuring integral rigidness and stability of the mast.

4 Section connection structure of main body is good for convenient disassembling/installation and transportation.

5 There is a buffer cylinder at the left side and right side of mast separately, which can be used for buffering and pushing while lifting and lowering down the mast.

6 The space and height of the mast both can meet the requirements of related top drive installation.

7 When the mast is used to match with the cryogenic rig, it mee ts the requiremen ts of drilling operation at arctic, because i ts main componen ts are made of -40°C high strength structural steel.

 
The main features of “mast” type mast:

1 The mast is a forward tilted type, with guyline, extendable and bi-section matched installation one.

2 The main body is a rectangular truss structure, with good rigidity, light weight.

3 Put the mast flatly on the front bracket of trailer when it is required to move; it mee ts the requirement of quick rig movement.

4 When the mast is used to match with the cryogenic rig, it mee ts the requiremen ts of drilling operation at arctic area, because i ts main componen ts are made of -40°C high strength structural steel.
