Benefits of technology

The patent text describes a way to safely work around manholes and sewerage openings. A barricade is set up to create a barrier to protect the working environment. All workers are required to be attached to an anchor point to prevent falls from heights. This invention helps to keep workers safe while working in confined spaces.

Problems solved by technology

It is widely known in the industry that opening a manhole is a high risk and fatal activity that requires operators to erect approved safety equipment in order to adhere to current legislation.
It is impractical and inefficient to erect and remove, in typical situations, safety barricades each time a manhole is needed to be inspected or maintenance to be carried out.

Embodiment Construction

[0043]Any embodiment of the present invention is meant to be illustrative only and is not meant to be limiting the invention. It is to be understood that throughout the specification that the term “cover” and “grate”; “invention” and “innovation”, will be used interchangeably.

[0044]FIG. 2 shows the topside of the temporary manhole cover according to the circular embodiment of the present invention. The manhole cover (1) consists of a flat ventilated plate with a semicircular hinged aperture (2) formed there through.

[0045]It is preferable that the circular embodiment and temporary manhole grate (FIG. 1a) be formed of a lightweight material such as aluminium or even in some circumstances a suitably strong plastic or non-ferrous composite material.

[0046]Where the temporary manhole cover will be used in a situation where operators may walk over it then it may be necessary to stiffen the plate by forming the plate with stiffening ribs (3) on the underside (FIG. 3) of the temporary cover....

Abstract

The Safety Manhole Industrial Cover (SMIC) is a lightweight temporary safety manhole cover with a hinged access door made with aluminium or a strong nonferrous composite used when sewerage, storm water, water maintenance or inspections are required. It is a temporary self-ventilating design manhole grate to be used whenever the manhole cover is removed when operations are in progress around the manhole. The slots allow for natural light and airflow and it allows workers below ground to see through to the persons above; and vice versa. The safety manhole cover is designed to eliminate the risk of falling from heights regulations requirement whilst works are carried out near or over sewer openings by allowing the operators to walk freely above ground without having a harness to secure themselves.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to AU2014101337, filed Nov. 8, 2014, which is incorporated herein by reference in its entirety.TECHNICAL FIELD[0002]The present invention is designed to eliminate the possibility of a fall from heights when working around openings.BACKGROUND[0003]It is widely known in the industry that opening a manhole is a high risk and fatal activity that requires operators to erect approved safety equipment in order to adhere to current legislation. It is impractical and inefficient to erect and remove, in typical situations, safety barricades each time a manhole is needed to be inspected or maintenance to be carried out.[0004]Manhole covers are heavy, typically circular, plates used to close vertical shafts, i.e. manholes. Manholes provide access to underground areas such as water and storm water pipes, sewage ways and other underground utility areas.[0005]The following is a non-comprehensive list of the procedure to ...
