WEI’s Hydraulic Elevator model

is a patented product designed and made by WEI, composed by external body with inside tapered surface with expandable die tongs and centering pipe ring, rotating device mounted on bearing with lubrication system.

Scope of work

It is very useful during tripping operation to avoid to screw/unscrew the DP and CSG for every connections.
This operation is done by two hydraulic cylinders that in closing position move inner inserts to the pipe already in the Elevator and catch it.
By opening the two cylinders, the DP or CSG is released.
It is safe and it saves time.
A light in the Elevator Control Panel advises the operator if the Elevator has caught or not the pipe.
Moreover it can be used also for mud circulation thanks to the installation of Packers.

Application

WEI Elevator is not only for WEI Drilling Rig.
It can easily be connected with other Top Drive brand only by a connection with saver sub API style.
