This document summarizes the design of a lifting table for power lithium-ion battery packs up to 1200mmx700mm and 1000kg. It includes the objectives of studying the device layout, structure analysis, design scheme, power calculations, and static and motion analyses. The lifting table can lift the battery packs to heights of 600mm, 650mm, and 700mm at speeds of 0.1-0.5m/s. The document reviews similar designs from literature and outlines the selection, calculation, design, and AutoCAD/Catia modeling of major lifting table parts like the lifting platform, hydraulics, and sensors. Force, stress, and motion analyses were performed on the scissor lift structure and hydraulic system

Structure design of lifting table for
power lithium-ion battery pack.

2. Objective of the Study
Layout of the device, structural analysis, overall design
scheme, power source calculation, static and motion
analysis.
The lifting platform can assemble battery packs up to
1200mm*700mm and 1000KG. The lifting speed is 0.1-
0.5m/s, and Height at 600mm, 650mm, and 700mm.
Structural analysis, calculation, selection, and 3D
modeling of major parts; AutoCAD assembly and part
drawings.

3. Literature Review
Utama Panwar, et al the design
of hydraulic scissor lift
components that lift up 300kg
of load with a raise of 3.5ft.
Gaffer G Momin, et al found
design and analysis of
mechanical, pneumatic, or
hydraulic type lift more
compact and suitable for
medium scale work.
N. Pandit, et al studied the
design, analysis, and safety
requirements of the scissor lift.
Safety of the worker operating it
and gives the guidelines for
handling the unit
Sandeep G. Thorat, et al
(2013) Scissor lift can lift a
load up to 4000 kg up to the
height of 7ft. The lift is easy
to use and daily maintenance
is not required,

13. Calculation of hydraulic system
• The Hydraulic scissor lift mechanism relies
on cylinders filled with a reservoir of
hydraulic fluid
• The flow of hydraulic fluid is controlled by
valves and causes the cylinder to push
outwards or retract inwards, with a
corresponding motion from the scissor legs
• Relatively easy to operate, hydraulic scissor
lifts are suitable for a range of applications at
different scales.
