Zusammenfassung:	A modular top drive (1) for construction of a wellbore includes a rail (2), a motor unit (1m) and a pipe handler (1h). The motor unit includes: a body (20), a drive motor (15), a trolley (22) connecting the body to the rail; and a first latch for selectively connecting either a drilling unit (1d) or a casing unit (1c) to the motor unit (1m). The pipe handler (1h) comprising a pair of bails (102b), a slide hinge (12) pivotally connecting the bails to the rail and a linear actuator (1a) for moving the slide hinge relative to the motor unit to a loading position. The top drive further includes a bracket (5, 6) for holding any one of a drilling (1d), casing (1c), and cementing unit (1s) and movable relative to the rail between a standby position and a connection position.
