Techcrane for Vane

Bunkering Barges

Techcrane installed two API mono- grammed model F10-60 cranes for the handling of petroleum product for Vane

Bunkering barges. Installed port and starboard, the cranes were customized for Vane to include a line payout system that is activated only under gross over- load to prevent damage to the crane.

Special brackets were mounted under- neath the boom to handle product pipe, which prevents the product hose from chaffing. The barges were built at

Trinity Marine shipyard in Tennessee.

Markey Debuts New

Electric Mooring Winches

Markey Machinery introduced a new line of low-cost Electric Mooring

Winches. Its new DESM-series of moor- ing winches is designed specifically for the next generation of coastal and ocean-class general-purpose barges,

ATB's, and short-haul barges, and include features which simplify installa- tion and long-term maintenance. Two models are available within the DESM- series, including: • DESM-18 single-drum mooring winch with hp electric-motor with a drum-capacity of 400 ft. of 1.125-in. line and a 60,000 lb. brake-capacity. DESMG-18R single-drum mooring winch featuring a warping-head, drum- clutch, and band-brake, with 20 hp elec- tric-motor, available in both right-hand and left-hand configurations. This model also has a drum-capacity of 400 ft. of 1.125-in. line and a 60,000 lb. brake-capacity.

Direct Hydraulic Drives for Deck Equipment

Hydraulic systems for deck equipment such as provided by Hagglunds elimi- nate gearboxes, and are designed for simplicity and better performance, as well as improved tension control and response. Weight and space is saved so the winches can be positioned better to suit the function and the safety of the crew. The power pack can be positioned anywhere, including below decks on smaller vessels, freeing up more space for deck operations. Lower noise levels are also evident and brakes are DNV approved. Power levels are optimized because a common pump can supply several functions and flow is directed to needed equipment only. A second pump provides standby facilities.
