BAG HANDLER

DISPOSITIF DE MANIPULATION DE SACS

English Abstract

The bag handler is a attachment used to grip jute bags or other items that can
be penetrated, it
uses 2 pneumatic or hydraulic cylinders to rotate via a linkage 2 sets of
protruding spikes at
either end of a rectangular frame to hold on to the parcel to be lifted,
To operate the bag handler it is lowered onto the item to be lifted via hoist
and is activated
with a switch forcing 2 pneumatic or hydraulic cylinders connected to the
shaft lever/rotating
shaft linkage to rotate the spikes towards themselves producing the gripping
pressure required
to hold the parcel to be lifted. The parcel then may be lifted with the
assistance of the hoist
and positioned where the operator dictates. To release the parcel the operator
releases the
cylinder pressure by deactivating the switch in turn rotating the spikes and
releasing the grip.

Bag Handler
By Michael Douglas Milton
The conception of this device is to reduce the risk of personal injury,
increase
productivity and lower costs for the handling of jute type bags in open or
restricted areas
ie:"cargo containers"
It is a 4 component apparatus consisting of (1) the base (2) the adjustable
swing arm (3)
the hoisting winch and (4) the grippes. Note the grippes is the key element in
the device
One person operates the device. Its primary functions to assist in the lifting
of heavy bags
for the palletizing or other lifting needs. Once the apparatus is positioned
near the bags to
be moved, the compressed air line is connected and the adjustable swing arm is
leveled, .
The operator, holding the hoist/gripper control handle positions the grippes
to latch onto
the desired bag. helshe then engages the grippes by activating a toggle switch
located on
the control handle, the hoist, grippes and bag are then raised into the air
supported by the
swing arm and manually positioned over the receptacle, pallet or bin that is
on or near the
swing arms platform, at such time the hoist is lowered or the grippes is
simply disengaged
to release the bag at the desired location.
