Design of Multipurpose Scissor Lift

Abstract

A scissor lift is mechanical device used for various application to lift load to certain height, raise or lower, transfer material one place to desired place. In this project design to reduce work time and increase productivity in market single design format is available in this design multi tool has attached to single scissor design to complete multi work to reduce error and increase productivity.

Introduction

1. I. INTRODUCTION

Scissor lift design used for reduce work, easy movable and reduce damage of goods. In this project scissor lift design model is multipurpose method it can easily alter and inter change structure to easy movable, reduce time, damages in goods. We can reduce cost of scissor lift to buy in individual design structure. Normally in market scissor lift design scissor lift design lift or move upward prefer height it has tilt or rotating object in prefer position to place. In this project single scissor lift model, we can extend height, rotation table or slide extend table can be used work has been done by use of hydraulic energy force. The frame is very durable and strong sufficient with structural design.

II. CONSTRUCTION AND WORKING OF SCISSOR LIFT

Scissor elevator device work with help of hydraulic cylinder inside hydraulic oil to move inside object to lift in vertical plane. Mechanism allows to vertical movement of load support in cross section ‘x’ pattern upward motion is applying force by actuator with help of pneumatic, hydraulic, mechanical support to move object vertically 

A. Hydralic Actuator

The lubricant oil is used to operate fluid pressure to lift load hydraulic cylinder pressurizes hydraulic oil speed variation is possible to temperature fluctuation that can alter viscosity of hydraulic oil.

B. Pneunamtic Actuator

The pneumatic method air pressure is compressing form atmosphere in cylinder. the pressurized air in move to cylinder to object. the pressure has to be maintained if it not any damage or leakage in air pressure object can’t be move or lifted.

C. Mechanical Actuator

The mechanical method rack and pinion or gear method to used object to lift or move or rotation. Benefit in mechanical method slipper or loss in pressure has reduce. This method easy and effective. 

III. MATERIAL SELECTION

Material selection is designing the component in performs in any damage in product and also to avoid accident occur the proper selection material selection is must. Different part of mechanism applies different material used mostly selection based on load apply in area and cost depend on it. normal force is applied in shear force cause bending properties such as strength, hardness and stiffness are should be consider. Main component of material selection is used mild steel it applies in base, frame, arm hence hardness and stiffness are required.

A large group of alloying components improves the compound physical/synthetic application. Compound might be added chromium (Cr), cobalt (Co), phosphorus(P), sulphur(S) manganese (Mn) chromium will reduce corrosion and increase steel hardness. Chromium oxide reduce corrosion and increase life of material.  different component is added to reduce wear and tear, rigidity, durable end goal is to be when force apply in components it should withstand and transfer goods in certain position. Force apply in the area segment are

1. Scissor arm.
2. Hydraulic cylinder.
3. Top platform.
4. Base platform.
5. Supporting arm.
6. Wheels.

A. Scope Of Project

1. Raise and lower lifting object.
2. To reduce time wastage.
3. To reduce damage in object.
4. Scissor lift accident can be control.
5. Safe work area.

B. Market Research

In market availability of scissor lift is single purpose only because of easy and depends on space and load factor of product moving or fixed base is set in area. Here project is chosen on four different type of scissor lift in design

1. Movable base with extended platform.
2. Vertical moving scissor lift.
3. Rotating platform base.
4. Removable with roller platform.
5. Support arm to reduce damage of load.

Conclusion

The hydraulic scissor lift is vertical movement of object design on the purpose reduce time and material handling process multifunction method is used in this method of design. Load transfer and material handling methos can be easily done by this scissor lift design is easy to understand the process of working how to reduce damage and increase productivity cost wise scissor lift is buying reduce because of multipurpose function.
