Our hydraulic driven LARS can be designed as portable systems, compact fixed

systems or as fully integrated winch and handling systems.

Docking mechanisms and turntable designs can be supplied in a range of

standard designs or tailor made to suit the requirements of the application and

the winch. The A-frame can be mounted on a single skid or as separate units as

preferred. If the winch is hydraulic driven, the power unit for the winch can also

be used to power the LARS.

All systems are designed and built according to DNV’s Standard

for Certification no. 2.22 - Lifting Appliances.

Portable A-frame handling systems

Our compact portable A-frame systems are designed to incorporate

our Cormac and oceanographic winches for efficient handling of

inspection ROVs, side scan sonar, survey equipment, oceano-

graphic instrumentation and a wide range of other equipment.

They are easy to control and provide the outreach needed

for safe launch and recovery. They can be supplied

with or without a power unit. We also offer other

basic over the side handling systems, including

J-frames and davits.
