A full-featured electric top drive for small-mast

applications.

The EMI 400 top drive system is the most versatile offering in

TESCO’s electric top drive line.

Designed for use on offshore and land based drilling rigs, the EMI

400 provides the performance and pipe handling features required

for drilling and workover applications.

The EMI 400 employs an AC induction motor and drive system.

The EMI 400 can be operated from a self-contained generator, or can

be connected directly to the rig’s AC Bus (600 VAC- 50 or 60 Hz).

The EMI 400 is capable of producing 298 kW (400 HP).
