APPLICATIONS
Offshore drilling operations
BENEFITS
■ Improved operational certainty and
efficiency with best-in-class performance
and reliability
■ Rig-time savings through simplified
maintenance
■ Enhanced range of applications through
modular design and ruggedized drilling
capabilities
FEATURES
■ Maintenance-friendly solutions
● Hydraulic valve blocks directly mounted
on rotation head
● Drip pans under all filters
● Access to all relevant maintenance
items if working platform mounted
between guiderails
● Swing-out blower design
● Docking pin that enables splitting
top drive body from main frame in
minimum time
● Lifting provisions on all items
● Disk brakes mounted inside coupling
bell housings
■ High-capacity thrust bearing
■ Helical-cut gear teeth (carburized and
grinded) that increase service life and
reduce noise level and maintenance
■ Gearbox lubrication for optimal
performance of gears and bearings under
all environmental conditions
■ Self-calibrating thread compensation
system that uses analog stroke sensor
to optimize performance
■ Onboard hydraulic system designed
to minimize the number of hoses and
fittings installed
■ Bell housings between AC motors
and gearbox that ensure perfect
alignment and protect the flexible
coupling between motor output shaft
and gearbox pinion shaft
The TD-500-AC-2M provides the highest level
of instrumentation, ensuring total control of
the drilling process while increasing uptime
and reliability through optimal system feedback
and redundancy.
Reliable automation
The TD-500-AC-2M top drive includes the
following features:
■ continuous high-accuracy monitoring
of weight on bit, motor temperatures,
lubrication oil temperature, and pressure
and bearing temperature
■ redundant motor and sensor configuration
■ flat gearbox design for optimal use of space
using extend-retract dolly and automated pipe
handling equipment
■ high-precision knuckle-link-type pipe handler
and link tilt with stop function
■ remote operation of all functions.
Simplified, safer operation
The top drive’s modular design ensures quick
and easy replacement of parts. All maintenance
and lubrication points are easily accessible
and protected from collision. Washpipe can
be replaced within 5 min. The pipe handling
systems include a high-capacity knuckle-link tilt
system that enables handling the latest-model
fail-safe elevator—from drilling to maximum
kickout mode.

TD-500-AC-2M
■ High-capacity stiff link tilt system for
handling the latest model of fail-safe
elevator—from drilling to maximum
kickout mode
■ Backup grabber that can handle tool
joint OD sizes from 4 in to 10 in without
changing die inserts
■ Washpipe that can be replaced
within minutes
■ Rotary head with 18 ports
