2. WHAT IS SCISSOR LIFT
A scissor lift with trolley is a device
used for lifting purposes, its
objective is to make the table
adjustable to desired height.

3. TYPES OF SCISSOR LIFTING
•Hydraulic lifting
•Electrical lifting
•Pneumatic

4. What Is Motorised Lifting
- 100 rpm
- 10 Volt DC
- High in torque in less rpm

5. Mechanism
• Extension is achieved by applying pressure
to the outside of a set of supports located at
one end of the mechanism, elongating the
crossing pattern.This can be achieved
through hydraulic, pneumatic, mechanical or
simply muscular means.
It may require no power to return to its
original position, but simply a release of the
original pressure.

Foam core or Foam board is a
very strong, lightweight, and
easily cut material used for
the mounting of photographic
prints, as backing in picture
framing.

11. ELECTRONIC COMPONENT

• RF RECIEVER

13. Wireless System
Adapters - 230 AC volt to 10 DC volt
DIP Bases - IC to translate the signal
Power Jack - Connector

14. APPLICATION OF SCISSOR LIFT
• Automobile Industry
• Construction Sites
• Railway And Aeronautical ind.

15. MAINTANENCE
IT WILL BE BASED UPON
1. Monthly maintenance
2.Semi annual maintenance

16. ADVANTAGE
1. Lift High load at less effort
2. Its Compact in size
3. It can wirelessly controllable
4. Highly efficient

17. Disadvantage
• Skilled Operator Needed.
• Lift raises too slowly with load.
• Motor heated after excessive use.

18. WARNING
• To avoid personal injury, never go under
the lift platform until the load is removed.
• Maintenance or servicing, electrical component
