Taken together, this AC 140 operating manual walks a crane operator or service technician through every superstructure system on the machine, from the first pre-start checks in the operator’s cab through the IC-1 load-limit device, counterweight assembly, telescoping sequence, and the optional attachments used for extended reach and light-load work.

What This Terex Demag AC 140 Manual Helps You Do

With this AC 140 operating manual in hand, you can correctly configure and operate the crane’s superstructure for a given job: selecting and fitting the right counterweight combination, running the IC-1 crane control through operating mode selection and the TableViewer for lifting capacities, telescoping the main boom manually or automatically with the locking and pinning unit, reeving the hoist rope through the correct sheave counts, and fitting the 9.1/17/25/33 m main boom extension, head roller, or runner when the job calls for it. It also documents the safety instructions, hand signals, and wind-speed limits that govern day-to-day crane operation.

Why the Original Terex Demag AC 140 Procedures Matter

The IC-1 control system, load limit device, counterweight combinations, and telescoping sequences on the AC 140 are all interdependent – an incorrect counterweight setting or a skipped step in the telescoping or counterweight-fitting procedure can shut the crane down or, worse, create an unsafe lifting condition. This manual gives you the manufacturer’s own sequence and torque/pinning details for each of those procedures, rather than leaving you to guess at the correct order of operations.
