Seatrax Remote Operated Emergency Power System

Seatrax, a crane manufacturer known for its superior products, has developed an emergency power system that easily solves problems caused in the event of a prime mover failure.

With this innovative system, crane operators can safely perform emergency load lowering, emergency boom lowering or emergency slewing with only the push of a button. Some of the features of Seatrax's system include...more.

Boom Hoist Kick-Out Overrides, Ramp Downs and Automatic Boom Locking Pawls

Often, we encounter crane specifications that go to great lengths to describe various schemes to hopefully prevent boom damage caused by abuse or unintentional use of the boom hoist kick-out override feature found on many cranes.

Seatrax cranes do not have an override on the boom hoist kick-out. We believe this lack of an override is a safety feature, which provides a great benefit to our customers.

We do not require overrides on our designs because our boom hoist-locking pawl is manually operated...more.

Emergency Hoist Brake Foot Button

The emergency hoist brake foot button is located on the left-hand side of the cab floor and is redundant to the fail-safe features of the Seatrax spring-applied, external contracting band drum brakes...more.

Seatrax Optional Boom Walkways

The Seatrax boom maintenance and work platform package includes a walkway down the side of the boom and is accessible from the engine deck side of the crane. Also included is a u-shaped maintenance platform at the boom tip from which servicing of all of the boom tip machinery, such as sheaves, main block, auxiliary hook, boom lights and SLI sensors, can take place. The walkway and platforms include bar grating, toe plates, mid rails and handrails...more.

Automatic Overload Protection System

An automatic overload protection system (AOPS) is a system fitted to an offshore crane intended to protect the crane from damage in situations where the hook is entangled with the supply boat, which subjects the crane to an unbounded gross overload outside the limits of any operational design condition. This system must be automatically activated and operational for all normal conditions including Hoisting, Lowering, Slewing, Luffing and at rest. This system must be operational for all reeving configurations and all operational hook radii...more.
