FIELD OF THE INVENTION
[001] The present invention relates generally to the field of a rotatable mobile
anchor. The present disclosure relates specifically to a rotatable mobile anchor for
providing protection to people working on the height from falling.
BACKGROUND
[002] As per Global safety standards and policy, any person working over a height
of 2 meters, needs to be protected or anchored with any arrangement which will
protect the fall of a person from that height. Research has shown that a maximum no.
of falls occurs when people are working at low heights and the fall can be fatal if a
person takes free fall for more than 2 meters.
[003] In order to use a conventional anchor known in the art, it is required to
excavate the area around the working plane and to make a foundation which together
made the anchoring base. This is time-consuming, costly, and disturbs the entire floor
and working area. Further, for placement of the anchors, breaking the existing
concrete also loosens the nearby concrete area.
[004] Conventional cantilever devices vibrate and slightly bend on the loading side
due to all weight concentration on the cantilever direction. Further, these cantilever
devices are cumbersome to assemble and time consuming in installation.
[005] Presently, there are many fall arrest and safety devices available in the market
to protect work at height. With such devices available, there is another permanent
arrangement available on site to install these devices and use when required. For
example – a person working on machinery or tank which has an overhead beam of
permanent anchor can connect this fall arrester to protect his fall.
[006] But under various conditions, such type of ideal arrangement where you get
an overhead or side permanent anchor beam or structure is not available. Also, there
are some conditional or working challenges, which restrict the arrangement of such
kind of permanent structures.
[007] A rotatable and mobile anchor is required when a person is working on a
machine or large fabrication unit where there is a movement of an overhead Electric
overhead travelling (EOT) crane. A person climbs over a chemical or oil tanker
outdoors to check the level or do an inspection. With the EOT crane on top, nothing
3
permanent below having an L shape for loading or unloading can be installed in the
line of action of the EOT crane. This might damage the crane or the anchor point.
There is limited or no space available for heavy devices. Where it is not possible to
excavate the ground to make a permanent foundation due to lack of space,
continuously working plant, cannot break existing concrete which will damage other
heavy materials, and need freedom of space and application. Multiple usages from
the same anchor point. A person working on airline blades for inspection in airline
industry and at various other applications across different industries.
[008] The mobile anchors known in the art are manual adjustable and very basic.
They use a separate self-standing ladder system for access to be used with mobile
protection device. Further, the mobile anchor devices known in the art are not having
any absorbing agent available to absorb dynamic and vibrational energy.
[009] There is, therefore, a need for a rotatable mobile anchor that does not require
excavating of ground area, is easy to assemble, install and dismantle in confined
spaces, is mobile and provides safety to the working person from falling.

[0056] The present disclosure described hereinabove has several technical
advantages including, but not limited to a rotatable mobile anchor. The technical
advancements are enumerated here. The rotatable mobile anchor is a mobile and
rotatable, which can be directly parked on any existing floor. The height of the
rotatable mobile anchor goes from 2 meters to up to 10 meters high neck anchor point.
Rotation assembly is fitted with a self-lubricating plates and bearing to allow the
entire top structure to rotate. Handle allows user to lock the rotation at its desired
location. Unique feature on the top anchor is the attached hydraulic cylinder. The
hydraulic cylinder has various important work to perform. They absorb vibration on
the device by distributing tension on the device. They support the additional load in
13
its opposite direction balances the entire device. They give additional strength to
device and add aesthetic value to the device. The hydraulic cylinder is used to adjust
the height of the anchor. The rotatable mobile anchor assembly is a unique device
which solves a major problem in the industry for providing a rotatable and mobile
anchor, with 2–10 meters of height and 0.5-2 meters of cantilever reach. This device
has anchor point which can be adjusted for various heights and reach.
[0057] The anchor assembly is telescopically slideable up and down for adjusting the
height and reach and be pinned at various angles to adjust the reach via the hydraulic
cylinder. The rotatable mobile anchor has a rotation assembly by which it can be
rotated with 360-degree coverage. The rotatable mobile anchor has provision for
multiple connections like rail system slider and trolley connection, and single anchor
point connection. Double folk anchor points are provided in the anchor assembly for
multi people attachment. The rotatable mobile anchor may has a connected foldable
ladder tray in ladder attachment, which has brackets to support ladder for access. The
ladder tray is designed to take counterweight support of system, rest completely on
ground, spikes to provide friction from ground, flat person standing area for
additional support. The rotatable mobile anchor is supported via counterweight of the
weight box to provide stability and strength in case of dynamic fall of person. The
rotatable mobile anchor is designed and tested for two people dynamic fall
simultaneously, which will lock the fall and not topple or twist. The counterweight
provided in weight box are in shape of cassettes, which can be added or removed, to
make the device light for long travels. Reducing the weight can allow easily towing
also. The rotatable mobile anchor has central storage in the weight box to keep all
important and necessary tools and PPEs inside the device itself, removing the need
to carry all separately. The wheels are hard rubber wheels with steering mechanism
to move the rotatable mobile anchor is in whichever direction needed. The outrigger
or breaking system is present to park the system in the desired working location. The
rotatable mobile anchor has a level controller which will help the user to identify
adjustments to its stability. It is painted bright yellow with zebra stripes for high
visibility.
14
[0058] Counter weight system of the weight box enables the rotatable mobile anchor
to make it free or self-standing. Further, the height of the anchor is adjustable via
hydraulic cylinder, inner and outer column to increase and reduce the height as per
requirement. The hydraulic adjustable cylinder also acts as an energy absorbing
system which absorbs the dynamic and vibrations energy coming at the time of fall
of person. Ladder tray to attach temporary ladder which make the ladder stable and
easy to install to use as a access to climb on other structures or machines. The rotation
assembly is designed such that the anchor assembly is moved at the point of usage
and also can be moved out when other works are going on.
[0059] While considerable emphasis has been placed herein on the specific features
of the preferred embodiment, it will be appreciated that many additional features can
be added and that many changes can be made in the preferred embodiment without
departing from the principles of the disclosure. These and other changes in the
preferred embodiment of the disclosure will be apparent to those skilled in the art
from the disclosure herein, whereby it is to be distinctly understood that the foregoing
descriptive matter is to be interpreted merely as illustrative of the disclosure and not
as a limitation.
