Safe Load Calculator (Platform structure dimensions for steel beams)
Assumptions:
1.
Maximum floor width = 1200 mm
2.
The GMA sits, and is positioned so as to transfer load through 2 beams.
3.
All materials are Grade 300 Mpa or better (AS3678 & AS1163)
4.
Floor is fully loaded at 2.5 Kpa (typical design load) - Is equivalent to 255 kg per m^2
5.
Floor mesh and handrails considered to be approx 50 kg per square metre.
6.
A 1.25x factor has been applied to the loads, for error in estimations of operators.
7.
It’s assumed the beams are full restrained, buckling has not been considered.
8.
15kN fall arrest anchorage load has been used to one side. This means 2 anchorages can
be used on the same device on either side.
3.0 Installation
Gridmesh Anchor Installation:
A. GMA Assembly (GA03):
The Gridmesh Anchor assembly is intended to be used
on steel structure with 1.2m centres, however can be used on narrower structures by
re-orienting the device diagonally (e.g. 900mm or 750mm). The model GMA04 has
additional equipment as second lifting point, however the total haul load MUST NOT
EXCEED 1.2 tonnes.
B. System height/clearance:
The Gridmesh Anchor should be located on a structure
where the height above the surrounding work area is sufficient to enable a chain
block / block and tackle to be operated in accordance with user instructions. If there is
insufficient clearance, DO NOT use the device.
C. Evaluate System Location:
The location of the Gridmesh Anchor(s) must be
determined by the user. Do not place any potential users at risk during the installation
and operation a completely installed system. Utilise the chart on Page 7 to determine
that the structure is suitable for use.
D. Inspection:
Before installing the Gridmesh Anchor on the mesh, both the mesh and its
structure should be visually inspected to confirm that it will hold hauling loads. If there is
any doubt about the ability of the system to sustain the loads, the system should not be
installed. If necessary, a structural engineer should validate the structural integrity of the
component members.
E. Risk assessment:
Prior to any job being undertaken, it is recommended that the user
undertake a risk assessment and prepare a safe work method statement (SWMS) to
ensure the equipment use and operation is within the manufacturer guidelines and the
operating requirements of the site.
Steps for Installation:
1. Using the storage bag, carry the Gridmesh
Anchor kit to the desired location. Ideally there
will be a user at the top of the structure to set the
anchorage on the mesh and a user below the
mesh to arrange connection to the equipment
from below.
