For workers on large stainless storage tanks, moving equipment around the top of the tank was very difficult. The tanks were built from the top down on hydraulic jacks, and used cranes and MEWP’s (Mobile Elevation Work Platforms) to move equipment at great cost to the build project.
Harken’s 46RWA Rewind Radial electric winch allows workers to easily hoist/lower an equipment cage using a rope. The rope leads through three 57 mm ESP pulleys installed at the top of the tank and down to the winch for operation. The Access Rail System allows workers to move the cage around the tank without using a crane or MEWPs.
