Hydraulic Hatch Covers

Hydraulic Hatch Covers our large or heavy duty access covers can be hydraulically operated. Hydraulic cylinders provide a higher power-to-size ratio compared to electric actuators, meaning operating cylinders can fit into smaller installed spaces.

Surespan’s basic hydraulic system comprises of operating cylinders with a hand pump and operates from topside or underneath. A typical access cover panel would take approximately 60 seconds to open from a closed position. Closing is achieved by releasing the hydraulic oil from the cylinder; the weight of the cover is sufficient to push the cylinder closed.

Features

  • Integrated hydraulic cylinders
  • Hand pump as a standard
  • 60 seconds close/open cycle
  • Closing using self weight
