A land drilling rig is used to drill oil, gas or geothermal wells. Modular systems can be completely packed together and moved to different locations.
Once it has arrived at the new location, the plant is assembled again to drill the next hole. Two parameters are decisive for the economic efficiency of the system: first, the installation space of the system, which should be kept as small as possible to enable a rig move with ease. Second, the time required for the rig move, as the system is not productive during this time.
Here, harnessed energy chains, readychain systems, are used. Since an e-chain runs through the trough system in a fixed installation space the mast can be made considerably smaller. To shorten the rig move time, the readychain system with Top Drive can remain in the mast during transport of the system.
A second solution is offered by the e-loop as a direct replacement for conventional service loops. This is also supplied as a readychain system and offers, compared to conventional loops, the advantages of an e-chain system in combination with a high-strength pull rope.
