Detailed Product Description
This kind of workover rig is a newly-developed double drum rig with windload guylines installed on the rig. Without the need to install external windload guylines,the workover operation efficiency is highly boosted, and installation area needed is decreased.
main features:
Suitable for narrow wellsite. Rig footprint is reduced.
Loads are evenly distributed based on mechanical analysis.
All the guylines are fixed on the rig, and the cost and work for anchors will be saved.
Equipped with inclination warning device to boost the safety of operation.
To maintain the operation stability under maximum hook load, full setback 60- knot wind load and empty setback 90-knot wind load, the rig is fitted with a series of self-tightening guyline device. They include guylines from crown block to deck frame, from mast lower sectiuon to deck frame, crown block to mast base, mast lower section to mast base, crown block to drill floor and racking platform to drill floor. To prevent overturning of the rig, deck frame is connected with a mud boat through pull rod, and a 10 cubic meters water tank counterweight is provided, and deadline anchor is removed from the deck frame to the mast lower section.
