ENSEMBLES D’ACCÈS À TRAPPE ARTICULÉE EN FONTE DUCTILE

Cette information est présentement disponible en anglais. Une traduction suivra sous peu.

Ductile iron access hatches have been designed for improved ergonomics. On a cover that can weigh as much as 550 lb, the lifting force required to open the cover is less than 35 lb due to the uniquely designed mechanical strut. The self-engaging safety bar provides added protection while the underground infrastructure is accessed, and safety grates can be specified for added fall through protection.

Simple and Reliable

The Ductile Iron Hinged Hatch incorporates safety and ease of access with EON LOCK® bolting and a self-engaging safety bar. The cavity and rubber plug in the EON LOCK bolt retain the nut when unbolted, eliminating the need to drill and tap the frame. The self-engaging safety bar provides added protection while the underground infrastructure is accessed, and a removable center beam provides a much greater clear opening access on several double hatch models. Removal/replacement of the safety bar is simple with 4 bolts securing the beam to the frame. To protect from worker injury, the cover opens to 105° but has a safety catch and removal at 90°.

Lift assist - Lift assist is a corrosion-resistant stainless steel mechanical spring strut. The rugged design is clean and maintenance free. The strut takes up less space in the clear opening than a traditional spring assist. It is fully self-contained, protecting coils from exposure to the elements. Made without internal gases or seals, the struts have an effective operating temperature range of -30°F to 400°F. The durability has been tested at over 150,000 cycles. This is a standard feature for airport rated models.

Safety Grate - An optional safety grate provides additional safety features. Doors cannot be closed unless the fall through protection has been put back in place (protecting the next operator). Visual inspections and limited maintenance can be done while safety grate is left in place. Orange safety grates create a visual barrier around the pit, which promotes awareness of the hazard. Safety grates can be locked independently of the hatch, adding another level of security when needed.

Forming Skirt - A forming skirt simplifies precasting the hatch in concrete – there is no need for added forming to protect the inner hatch. The leave-in-place aluminum skirt can be made to fit any concrete slab thickness.
