Hoist Drum Rotation Indicators

The system consists of three different components for each hoist: a transmitter, a driver and an indicator. The system is bi-directional and extremely precise. The system can be installed on any or all of the hoists on a crane...more.

Hoist Lowering Dynamic Braking and Speed Control

The dynamic brake valve is attached to the motor without the use of hoses as required by API Specification 2C for hydraulic cranes. Its primary purpose is as a safety device to prevent gravity from running away with vertically-suspended loads. This is accomplished by applying positive pressure in the downward direction to slightly pilot open the dynamic brake valve. (The dynamic brake valve requires positive pressure from the power source to release-also an API Specification 2C requirement)...more.

Seatrax "SB Series" Platform Utility Cranes

• Proven Safety Features


• API Type E kingpost design. No "Rotek"-type slew bearings or attachment bolts that can fail needed. The crane is permanently welded to the platform topsides.


• Integral anti-two-block feature. No hanging weights, boom-mounted valves or hoses required.


• Cable-suspended boom ensures smooth and safe lowering of the boom.


• External fail-safe drum brakes on Seatrax hoists. Geartrain failures need not result in loss of the load...more.

Seatrax Counter-Luffing Boom Kick-Out

With the growth of the oil and drilling industries moving toward deep water offshore operations, more supplies and larger equipment are stored on location. Many platforms and rigs continue to lose storage and working space. This lack of space combined with platforms' increasing size, requires cranes be equipped with longer booms that must work at closer radii to maximize the use of available deck space.

To solve these problems, Seatrax uses its patented boom stop. The hydraulic boom stop offers several advantages over conventional spring hard boom stops, which include...more.
