DESIGN FEATURES

• Improved ergonomics:
• Hinges reduce the physical effort by 50%.
• Hinges allow operator to move in a straight line, thereby avoiding damaging spinal rotation.
• Hinges minimize the duration of the lift; the hinge also retains the cover in a safe and controlled way during and after the lift.
• Lifting points in the cover are designed for use with standard tools (pickaxe/hook/bar).
• Hinge incorporates a 90º blocking feature to prevent accidental closure.
• Self-centering design of the gasket eliminates the need to guide the cover into position when closing.
• Design of apertures ensures easy insertion and removal of tools.
• Lifting loops in the frame facilitate safe offloading and installation with the proper equipment.
