The EC 20

The Light Duty / Low Maintenance Box-Boom for Unmanned single caisson structures

Energy Cranes EC20 is a proven machine developed from the popular Titan 5B.

Designed to withstand arduous service on substantial manned offshore installations and drilling rigs, in a typical 30ft (9.1m) boom configuration, the EC20 delivers 12,200 lbs (5.5 tonnes) on-board and 8,100 lbs (3.7 tonnes) off-board load capability at 10ft (3m) radius.

Designed and manufactured under API 2C-6th edition, the EC20 can be configured to optimize the on-board and off-board capacity by utilizing the established methods within API 2C.

Rotating Structure
The reinforced base plate, to which the bearing, gearbox, and luffing cylinders are bolted, virtually eliminates shock-load and, in consequence, extends bearing life. The symmetrical superstructure avoids localised stress.  Continuous 360° swing control is delivered through two heavy duty hydraulic planetary drives, with static and dynamic brakes, mounted to the ball ring so as to facilitate ease of inspection/maintenance of all retaining bolts.

Boom & Load Control
Box Booms are available from 20 to 40 ft (6.1-12.2m) in length. A jib extension accommodates the auxiliary hoist line/sheave. A boom luffing cylinder, equipped with a counter-balance valve is utilized to control the boom position. Main and auxiliary hoist control comes from hydraulic planetary hoists equipped with counter-balance valves for power load-lowering. Automatic spring-applied hydraulic release brakes and ratchet/pawls are fitted.  Safety kick-outs such as Anti-2-Block are standard.

Operator’s Station
An operator’s station can be mounted on the body (walk-around) or remote based on the project requirements.  Hydraulic controls have dead-man failsafe and there are pressure gauges for each pump. The control panel includes prime mover controls/gauges.
