Name That Crane

We often get inquiries along the lines of, "We need a 100-ton crane." So, what exactly is a "100-ton" crane? This can mean many different things to many different people, which is why we need a common term of reference. To define this term, we need to look at a little background.

The Offshore Oil & Gas industry was established in 1954 with the first fixed platform installed near Morgan City, Louisiana in the Gulf of Mexico. The only cranes available for use on these early platforms were existing land-based construction machines, such as crawler cranes. The designation system the offshore industry used was the same one as used to identify construction equipment in the United States. That designation system was developed by the American Power Crane and Shovel Association prior to WWII and has been used to classify or "name" mobile construction cranes since that time. This system uses a naming convention based on tonnage....more.

Redundant Boom High Angle Limit System

Redundant Boom High Angle Limit System

The electric boom angle limit system is simply designed to use a solenoid valve to redirect the joystick "up" signal from the control valve to the tank. This system incorporates sensors on the boom base to override the boom hoist hydraulics.

When the boom comes within two inches of the boom stops, the sensors send an electrical signal to a solenoid valve. The solenoid valve is installed in the hydraulic signal line between the standard boom kick-out and the boom hoist control valve...more.

Wave Follower

Constant Tension Device-"Wave Follower"

Seatrax offers a constant tension device appropriately called a Wave Follower. The Wave Follower allows an operator to attach large loads in heavy seas by reducing of risk of damage to the crane, load or supply vessel. The Wave Follower accomplishes this goal by allowing the hoist line to "yo-yo" at a low back tension prior to liftoff from the supply boat deck...more.
