This operating manual covers the complete Liebherr CBB 450(250)/17(30) crane from initial commissioning through to routine maintenance. The safety chapter alone spans nearly 25 pages of detailed guidance on danger symbols, machine-specific hazards, personal protective equipment, and safe working practices for offshore lifting operations. The control and operating elements chapter walks through every joystick, push button, switch, and monitor page, making it an essential reference for anyone unfamiliar with the Litronic control system or SYCRATRONIC synchronised lifting mode. The crane operation chapter details daily start-up, parking procedures, preselection of hoist gear, and the dynamic anti-collision system (DACS), while the emergency operation chapter provides step-by-step procedures for lowering loads, releasing slewing brakes, and lowering the boom using the emergency hand pump when the crane has lost power or a power pack has failed. The maintenance chapter provides the full schedule of lubrication points, oil specifications, rope inspection criteria, and condition monitoring guidance.

What This Manual Enables You To Do

With this Liebherr CBB 450(250)/17(30) operating manual, you can confidently operate the crane through its full working range, from daily start-up checks and hook operation to SYCRATRONIC tandem lifting with a second crane. It gives you the correct procedures for selecting main or auxiliary hoist, setting the load moment limitation, and working within the permissible wind speed and heel/trim limits. For maintenance teams, the manual provides the complete schedule of greasing points, gearbox oil specifications, rope discard criteria, and hydraulic filter replacement instructions. The emergency operation chapter is particularly valuable for offshore work, giving clear procedures for lowering a suspended load, releasing slewing brakes, and lowering the boom using the emergency hand pump when normal power is unavailable. The safety chapter equips operators with the knowledge to identify hazards, use the correct personal protective gear, and understand the meaning of every safety sign on the machine.

Why Correct Procedures and Specifications Matter

The Liebherr CBB 450(250)/17(30) is a 450-tonne SWL offshore crane with a 35-tonne auxiliary hoist, a 30-metre maximum main hoist radius, and a 360-degree slewing range. It is fixed on a ship and designed for loading and unloading operations in demanding marine conditions. Operating outside the load chart, using incorrect reeving, or ignoring the wind speed limits can lead to structural damage, load loss, or serious injury. The maintenance intervals, lubricant specifications, and rope discard criteria in this manual are not generic recommendations — they are the manufacturer’s requirements for keeping this specific crane safe and operational. Having the correct operating manual for your serial number ensures you are working from the right load charts, the right emergency procedures, and the right maintenance schedule.
