Seatrax Hoist Inspection Requirements Disassembly and internal inspection of the gear reducer components during Annual Inspections or other routine inspection intervals is NOT REQUIRED and is NOT RECOMMENDED. Disassembly and internal inspection of the gear reducer components is only required if any of the following conditions are encountered during operation:

Why Seatrax Doesn't Use "Braden"-Type Winches Seatrax does not use "Braden"-type hoists or other hoists of the "works in the drum" design. Instead, we make our own hoists, which are superior to the "Braden"-type hoists in this application. Our reasons for this are as follows:

Closed vs. Open Loop Configurations for Hoisting Applications Seatrax uses an open loop configuration for all of its variable displacement hydraulic systems, which are used for hoisting applications. These systems utilize the same type of variable displacement, high pressure, piston pumps that are used on the more familiar European closed loop systems. Seatrax's open loop configuration for this same type of equipment provides equal or better infinitely variable speed control in both directions of movement and addresses well-known safety and maintenance concerns that continue to be a problem with the closed loop system configuration...more.
