4.1

Application

Outward opening manhole cover type HLSD-2 is used on top of pressurized tanks and containers where closeable means
of access to the interior of the vessel is required. HLSD-2 is approved and can be used on pressure vessels according to
PED 97/23/EC.

4.2

Working principle

HLSD-2 is secured in the closed position by swingbolts, which, together with the seal in the cover, ensure complete tightness.
The cover is attached to the frame by a rigid hinge, giving exact location of the cover in the closed position and designed to
stop the cover at an angle of 20-30° beyond the vertical position when opening.
