Castings strong enough to handle severe loads are inherently heavy. Lifting these heavy lids/gates to gain access to sub-ground utilities has been an issue for maintenance crews. Lifting these heavy covers requires multiple personnel and lifting equipment. With Neenah’s Spring-Assist Hatches, a single maintenance worker can quickly open the lid, and secure it in the upright position with Neenah’s hold open device and perform the necessary work.
FEATURES UNIQUE to the NEENAH R-3498 SERIES
