The EC 1100

The high performer for heavier loads or deepwater operations

Energy Cranes EC 1100 is a proven design introduced in 2005 as a development of the earlier American Aero OM2200.

The EC 1100 meets the requirement for an offshore pedestal crane with 220 US tons (199 tonnes) close-radius performance balanced by a useful 58 US ton (53 tonnes) off-board lift capacity at nominal 50 ft (15.25 m)radius. The EC 1100 is in particular demand for large Tension Leg Platforms (TLPs), SPARs and lift boats.

Designed and manufactured under API 2C-0072 6th edition, the EC1100 can be configured to optimize the on-board and off-board capacity by utilizing the established methods within API 2C.

Performance load chart snapshot

Rotating Structure
The heavy-duty welded-steel base plate supports the swing bearing and gear box. A 109” (2.77m) three-row roller swing bearing is standard. Continuous 360° swing control is delivered through heavy duty hydraulic planetary drives, with static and dynamic brakes.

Boom & Load Control
74” x 74” (1.88 x 1.88m) cross-section lattice booms are available from 100ft - 200ft (30.5m - 61m) in length.

Boom Luffing
Boom Luffing and Load Hoisting are through hydraulic planetary hoists equipped with counter-balance valves for power load-lowering. Automatic spring-applied hydraulic release brake and ratchet/pawls are fitted. Boom suspension is of the pendant line/bridle type. Spring rubber boom backstops, high boom-angle kick-out and Anti-2-Block are standard.

Operator’s Cab
The standard ‘full vision’ cab is fully enclosed and fitted with shatter-resistant glass. Hydraulic controls have dead-man failsafe and there are pressure gauges for each pump. The cab control panel includes prime mover controls/gauges.
