CHAPTER I
THE PROBLEM AND ITS BACKGROUND AND REVIEW OF RELATED
LITERATURE
Introduction
In our generation, many people are continuously constructing houses and
buildings. But construction is a high hazard industry, workers are exposed on
activities that might put their lives in danger, such as lifting and transporting of
materials on a construction field. It has been one of the hardest works that gives
so much problem to the workers. So, what product should the researcher can
provide in order to help workers? Is it more convenient and safer tool?
The most conspicuous utilization of pressed wood is in primary
applications. Compressed wood can normally withstand a ton of stress and full
climate openness. Underlying compressed wood is best utilized for shafts and
hoardings, however it is generally utilized in cases, canisters, interior designs,
open air furniture, and boxes. In order to lift a plywood for a building construction
we utilize our exposed hands with the goal that it takes a ton of laborers to lift a
pressed wood. When holding an object with an extremely small mass applying
precision grip, the grip load examination was scrutinized healthy adults (N=17)
grip a portable apparatus, further measurement of grip force dependent finger
surface contact location and finger skin indentation as well as the discrimination
of test of weight. The parallel relationship was change when the object is smaller
than 30 g. safety margin in the static grip force and normalized to moment were
2
also elevated towards the lower end of the object and both surfaces. The result
indicated that the strategy of grip force with extremely small mass differs with a
mass above 30 g. skin indentation and weight discrimination decrease the level
of cutaneous feedback signal from the finger pads might have played some role
in efficient grip force to control low mass objects, the signal dependent, internal
noises and anticipated inertial forces on the object due to acceleration of arm and
hand also contributed to the cost function. (Hiramatsu et al. 2015).
According to Stefan R. (2017), the common practices in industries is
manual lifting to move or transport an object to desire place. Nowadays,
mechanized equipment is popularly available as an essential way of manual
lifting which is still considered to perform material handling task. It is important for
construction, which require numerous materials, and people that directly affects
the value and time of construction.
The Bachelor of Technical Teacher Education Major in Civil Technology
Students of Valenzuela City Polytechnic College is building research about an
Four-wheeled trolley rack to transport and store plywood and lumber. First,

Foreign Literature
This project aims to develop a cart-trolley that can support the physical
distribution of goods. Currently, this process is carried out using manual tools
and equipment. This system consists of three components, namely, a cart, a fork,
and a flat plate. When stretched, the system turns into a cart, while when tilted, it
elevates the cart. It then turns into a trolley when folded. The system is controlled
by a pair of wiper motors. The circuit board is composed of a wireless module,
relays, and wires. The microcontroller (ESP8266EX) is used to control the cart's
operation. The cart-trolley was tested and showed that it could handle the weight
of various objects with high efficiency and throughput. (Oluwayomi J. et al., 2020)
Manual handling and repetitive tasks involving the use of manual props
and pull forces are very common in factories and industrial settings. Doing these
activities can become dangerous and cause injuries if done improperly. The
study involved the evaluation of the pull strength of an apparel cart/trolley puller
and the muscular activity of upper limbs. The data was collected through an
electronic data acquisition system (IDSA). Electromyographical data was
collected on the muscles involved in the pull tasks. The subjects were observed
to perform pull tasks while seated. The results indicated that the isometric value
of torso pull while seated is higher than that of arm lift. Time study is a process
utilized for measuring the times required for various tasks in a repetitive
manufacturing process. This technique is commonly used in garment production

8
lines. The factory was producing work wears for men and women. The study
analyzed the existing set up and its effects on the production line. The findings
revealed that the existing set up could be improved through a series of activities
and line balancing. A time study was carried out to analyze the productivity of a
machine before and after implementing various changes. The results indicated
that the productivity boost was significant. The study revealed that by using a
process that is optimized for material flow and production line, it can reduce work
in process and make the finished products more attractive to customers. (Savino
M. et al., 2019)
Foreign Study
The studies highlight the intelligent trolley has provided more
convenience, besides convenience it has save time there is no need for the
consumer to stand and wait in the long queues to pay for they purchases which
the customers have been complaining about before. My research conducted over
the intelligent trolley highlights the impact it had over the supermarkets and the
retail store. this research revealed that the introduction of this technology would
require some finance and the stores would have to bare some cost in order to
upgrade the IT systems. The introduction of intelligent trolley would provide
competitive edge to the stores as they would be offering extra services to the
customers. The price that the store are offer are almost the same these new
9
features offered in the form of intelligent trolley would attract more customers.

The aim of this work is the non-linear study by the finite element method (FEM)
of the mechanical performance of timber joints’ systems for the beam elements
used in the construction of roofs, whenever they are bent at the same plane. A
full three-dimensional numerical analysis was carried out assuming an
orthotropic behavior model of the material with a failure criterion based on the
requirements of the Eurocode 5 rule. The non-linearity is because of the contact
between the joint's bolts and the wood's components and compressed wood's
components just as the huge removals in the framework. The investigation
likewise incorporates the full-scale exploratory trial of six whole brackets of 6 m
range and 1.0 m high, subject to bowing in four focuses as indicated by the
system set up in the UNE-EN 595:1996 standard. Three examples have the
association object of this investigation while the other three leftover ones have
the steel fitting utilized consistently in these wood structures. The purpose of this
work is to replace the joint pieces used regularly up to now, built with steel fitting,
with other pieces made with wood’s sections obtained from birch plywood board.
This aim is achieved comparing the resistant characteristics of both connection
methods and validating the developed numerical model. In order to know the
influence of the most important variables in the structural behavior of the plywood
board timber connection, a design of experiments (DOEs) is carried out. Finally,
the more meaningful conclusions from the models and analyses carried out are
10
exposed, showing a good agreement between the numerical results and
experimental tests, as well as a very similar performance between the connection
systems analyzed: steel fittings and birch plywood board. Diaz D. et al., (2012)
Local Literature
Storage rack systems are made up of columns, beams, and bracing made
out of cold-formed steel structural elements. The rack columns have unusual
design features in that they include perforations to aid in system assembly,
making them more challenging to evaluate using cold-formed steel structure
design rules. There are many design codes proposed by manufacturers
associations, such as the Rack Manufacturers Institute (RMI) specifications,
which are used in the United States alongside the American Iron and Steel
Institute specifications (AISI). For determining the resistance of stub columns,
these programmed suggest experimental stub column testing. The commercial
software ANSYS is used in this study to perform material and geometric non-
linear analysis of these columns, and the findings are compared to experimental
data obtained through stub column tests for a typical piece of racks built in Brazil.
(Khosrow G, Eduardo M. 2005)
Local Study
Manual material handling (MMH) task contributes to a large percentage of
musculoskeletal disorder cases and injuries in occupational settings.
Musculoskeletal disorders (MSD) often involve strains and sprains to the lower
back, shoulders, and upper limbs. They can bring about the openness of laborers
11
to hazard factors that at last transform into expensive wounds and lost
usefulness. A few examinations have shown that powerful ergonomic mediations
can diminish the actual requests of manual material dealing with undertakings in
this way bringing down the event and seriousness of MSD and word related
wounds. To control the nature and severity of these injuries in the MMH task, this
paper aims to design an ergonomic trolley to assist the tasks of workers. The
researchers were able to come up with a design of a 6-wheel trolley that has the
capacity to carry a load of 100-kg weight. It has a Tri-Star hub that rotates to
overcome uneven floors and stairs that will enable to single-handedly transport
load safely. Moreover, the handle stature and handle breadth of the streetcar
depended on anthropometric components of Filipino laborers to be specific
standing elbow stature furthermore, handgrip breadth to coordinate with the plan
of streetcar to the anthropometric necessities of Filipino clients. The 3D design of
the trolley was made using Fusion 360 software. After which, the trolley was
fabricated using a plasma cutter and lathe machine. It was then tested on three
different pushing positions (rough surface, elevated surface, and staircase) to
compute for its mechanical advantage. The researchers then analyzed and
computed for the actual force that must be applied comparing it to the load that
can be transported by six-wheeled trolley. The findings of the study have proved
that the newly designed trolley will be able to reduce the risks in manual pushing
and pulling operations involving whole-body effort as evidenced by the result
RAPP tool analysis. (Querubin M. et al., 2020)

CHAPTER II
METHODOLOGY
This chapter presents the research design, respondents, setting,
and research instrument, procedure of data gathering and statistical treatment of
data used in this study.
Research Design
The experimental and descriptive-evaluation method of research
employing a questionnaire and documentary analysis was used since this study
dealt only with the level of acceptability of four-wheeled trolley rack to transport
and store plywood and lumber. Copies of the questionnaire were issued to the
target respondents who are construction workers in the City of Valenzuela to
obtain a comprehensive data about their perception as to the claims of the
device. Analysis of the data was likewise undertaken to gather substantial
information of their perceptions.
Descriptive method is a research method that describes the features of
the population or subject under investigation. This methodology emphasizes the
"what" of the research subject rather than the "why" of the research subject.
Experimental method is research involves the manipulation of variables to
establish cause and effect relationships. The key features are controlled methods
and the random allocation of participants into controlled and experimental
groups.

Statistical Treatment
The research study
used the following statistical tools:
percentage, mean, weighted mean,
chi-square test, and Likert
scale.
Percentage- the use of percentage distribution was employed to find the answers
to the questionnaire checklist profile formula.
Formula:
P = f x 100
Where:
P= Percentage
f = frequency of respondents
21
n = total number of respondents
Mean – refers to the average that is used to derive the central tendency of data in
question
Formula:
Where:
X = mean
= total sum of the product of x and frequency
n = given sample data
Weighted Mean = weighted average is a mean calculated by giving values in a
data set more influence according to some attitude of the data.
Formula: WM = TWF/N
Where:
WM= Weighted Mean
TWF= total weighted frequency
N = Total number of respondents
Chi-Square Test = the Chi-Square statistic is commonly used for
testing relationships between categorical variables. The null hypothesis of

22
the Chi-Square test is that no relationship exists on the categorical variables in
the population; they are independent.
Formula:
Where:
Chi-square test
O = Grand total observed frequency
E = total product of frequency
Expected Frequency- are counts calculated using probability theory.
Formula: E = RT x CT
OT
Where:
RT = Row Total
CT = Column Total
OT = Overall Total
Degree of Freedom - Degrees of freedom are the number of independent values
that a statistical analysis can estimate. This is used to look the critical values for
an equation using a critical value table, which in turn determines the statistical
significance of the results.
Formula: df = (r-1) (c-1)
Where:
23
r = Number of Rows
c = Number of Columns

In our generation, many people are continuously constructing houses and

buildings. But construction is a high hazard industry, workers are exposed on

provide in order to help workers? Is it more convenient and safer tool?

The most conspicuous utilization of pressed wood is in primary

hoardings, however it is generally utilized in cases, canisters, interior designs,

grip a portable apparatus, further measurement of grip force dependent finger

hand also contributed to the cost function. (Hiramatsu et al. 2015).

According to Stefan R. (2017), the common practices in industries is

manual lifting to move or transport an object to desire place. Nowadays,

mechanized equipment is popularly available as an essential way of manual

the value and time of construction.
