PROJECT TITLE : UNIVERSAL DRUM HANDLER

INTRODUCTION

DRUM HANDLERs

Only thoroughly trained and competent persons are permitted to operate DRUM

HANDLERs. Operators should know what they are lifting and what it weighs. The rated

capacity of mobile DRUM HANDLERs varies with the length of the boom and the boom

radius. When a DRUM HANDLER has a telescoping boom, a load may be safe to lift at a

short boom length and/or a short boom radius, but may overload the DRUM HANDLER

when the boom is extended and the radius increases.

All movable DRUM HANDLERs must be equipped with a boom angle indicator; those

DRUM HANDLERs with telescoping booms must be equipped with some means to

determine the boom length, unless the load rating is independent of the boom length. Load

rating charts must be posted in the cab of cab-operated DRUM HANDLERs. All mobile

DRUM HANDLERs do not have uniform capacities for the same boom length and radius

in all directions around the chassis of the vehicle.

Always check the DRUM HANDLER's load chart to ensure that the DRUM HANDLER is

not going to be overloaded for the conditions under which it will operate. Plan lifts before

starting them to ensure that they are safe. Take additional precautions and exercise extra

care when operating around power lines.

Some mobile DRUM HANDLERs cannot operate with outriggers in the traveling position.

When used, the outriggers must rest on firm ground, on timbers, or be sufficiently cribbed

to spread the weight of the DRUM HANDLER and the load over a large enough area. This

will prevent the DRUM HANDLER from tipping during use. Hoisting chains and ropes

must always be free of kinks or twists and must never be wrapped around a load. Loads

should be attached to the load hook by slings, fixtures, or other devices that have the

capacity to support the load on the hook. Sharp edges of loads should be padded to prevent

cutting slings. Proper sling angles shall be maintained so that slings are not loaded in

excess of their capacity.

All DRUM HANDLERs must be inspected frequently by persons thoroughly familiar withthe DRUM HANDLER, the methods of inspecting the DRUM HANDLER, and what can

make the DRUM HANDLER unserviceable. DRUM HANDLER activity, the severity of

use, and environmental conditions should determine inspection schedules. Critical parts,

such as DRUM HANDLER operating mechanisms, hooks, air or hydraulic system

components and other load-carrying components, should be inspected daily for any

maladjustment, deterioration, leakage, deformation, or other damage.

PROBLEM DEFINITION :

In the present age of industrialization material handling using modern material handling

equipment has become an absolute necessity.but in some cases the conventional methods of

material handling such as the fork lift cannot be used for example unloading of a drum or barrelfilled with liquid.

Drum handling is necessarily a tedious activity if considered individually by using manual

methods or the DRUM HANDLER, because tilting a drum filled with oil/liquid without spilling is

difficult . This needs a specialized equipment which can do the emptying of the drum easily and

fast without any wastage.

SOLUTION:

The universal DRUM HANDLER is an ideal solution to the above problem where in one

can do the following functions:

a) Holding the drumb) Tilting the drumc) Transporting the drumd) Rotating the drum (Sometimes necessary for mixing purpose)This present unit is an prototype model of the actual system only reduced in capacity (drum

weight and size)rest functionality is duplicated. .due to economic considerations.

CONSTRUCTION OF UNIVERSAL DRUM HANDLER


3/6

THE UNIVERSAL DRUM HANDLER comprises of the following parts :


4/6

a) Base Frame : The Primary base frame is the base element provided withcastor wheels, The primary base is made of mild steel square tube and mild

steel plate. It supports the entire assembly of the DRUM HANDLER system

b) Vertical motion system: The vertical motion system comprises of the screwand nut , lifter screw held in two ball bearings and nut connected to the

carrier. Rotation of screw is converted to translation of the drum tilter unit

up or down

c) Drum Gripper arrangement :The drum gripper arrangement is in the formof two LH and RH clamp heads , Rh head is fixed andf the Lh clamp head

moves to and fro to achieve the clamping and de-clamping arrangement.

The clamp screw is translated to and fro by rotating the clamp nut using

clamp motor.

Specifications of the motor and gear box are as follows

Motor : 12 Volt DC , 50 watt

Gear box : worm gear box 1:55 ratio

d) Drum tilting / rotation mechanism : This system is used to enable the tiltingor rotation of the drum . this is achieved by means of a spur gear ring

driven by a pinion on the tilting motor. Rotation of the drum can be done

keeping the tilting motor running.

e) Power to the system is given by 12 V DC battery /12 v DC sourcef) Direction control is achieved by using a 2-Pole 2-way (DP/DT) switch.

WORKING

The Working of the UNIVERSAL DRUM HANDLER is best explained using

following procedural steps:

1. DRUM LIFTING / TRASPORTATION:The drum to be lifted is approached by moving the DRUM HANDLER

using wheel castors , the gripper motor is started to bring the gripper

jaws inwards to clamp the barrel.

The rack arrangement is actuated using pinion and handle

arrangement to lift the drum.

The drum is moved to the desired location by moving the DRUM

HANDLER using castor wheels.

2. DRUM TILTING :The drum to emptied is approached by moving the DRUM HANDLER

using the castor wheels. The gripper motor is started to bring the

gripper jaws inwards to clamp the barrel. After the drum is securely

gripped the tilting motor is started to tilt the drum to desired angle to

facilitate the drum poring activity.

3. DRUM ROTATION:The drum to be rotated is approached by moving the DRUM HANDLER

using the castor wheels. The gripper motor is started to bring the

gripper jaws inwards to clamp the barrel. After the drum is securely

gripped the tilting motor is started to rotate the drum to desired no. oftimes.

ADVANTAGES :

1. Conventional lifting is possible.2. Tilt to right hand side possible.3. Tilt to left hand side possible.4. Drum rotation to 360 degrees is possible5. Tilt angle is lockable as self locking worm gear box is used for tilting and

gripping

6. Low cost automation.

APPLICATIONS:

1. Liquid material transport.2. Industrial fluids transport3. Agriculture fluids transport4. Garbage Trucks ..etc.
