Bulldozer as machinery equipment
A bulldozer is a tracked tractor equipped with a substantial metal plate called a blade used to push large quantities of material like soil, sand, and rubble during construction. It consists of a tractor with a front-mounted blade controlled hydraulically to cut and level land. Bulldozers are classified based on their mounting (crawler or wheel tractor) and blade type (front casting or angled). They are used for tasks like clearing sites, leveling land, excavating, and backfilling. Productivity depends on factors like the operator's efficiency, soil type, and topography. Larger bulldozers have greater operating ranges and capacities than smaller ones.
Bulldozer
Bulldozers are large, tracked heavy equipment vehicles equipped with a metal blade used to push soil, sand, rubble and debris. They have excellent mobility over rough terrain thanks to their continuous tracks. The primary tools of a bulldozer are the blade, used to push material, and the ripper, a claw-like device used to break up compacted materials. Bulldozers are commonly used in construction, mining, forestry and other industries for earthmoving tasks.
GRADERS
A grader is a construction machine that uses a long blade to create flat surfaces. Early graders were pulled by animals or engines, but the first self-propelled grader was created in 1920. Graders are now commonly used to prepare surfaces for roads, clear snow, and create tracks on large farms and ranches. They can shape surfaces and add camber to roads using their adjustable blades.

Under earth-moving equipment, it describes common machinery such as excavators, bull dozers, motor graders, scrapers, and trenching machines. It also discusses dozers in more depth, outlining their applications, components, and different types including crawler and wheel models. The document aims to inform readers about heavy machinery commonly used at construction sites.
Modern construction equipment raaj2
The power shovel is a large, electrically-powered excavating machine used for digging and loading earth or fragmented rock. It consists of a revolving deck, counterweight, boom, dipper stick, and bucket. The basic operations are hoisting the bucket, crowding it in and out, swinging the deck, and propelling the machine. Power shovels are suitable for large lifts, excavating blasted rock, tough soils, and projects requiring high hourly output. They excavate trenches and remove boulders faster than other methods, but use more fuel and are harder to transport between sites. Maintenance and operation require technical skill.
Mine Power & Drainage System
The document provides information on various mining equipment used for both surface and underground mining. It describes the bucket wheel excavator (BWE) which is a large continuous mining machine that excavates and loads material using a rotating wheel with buckets. It also discusses power shovels which operate cyclically to load and haul material. For underground mining, it outlines the shearer, a cutting machine used in longwall mining, and load-haul-dump trucks (LHDs) which are used to transport excavated material cyclically within the mine.

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Design and optimization of ion propulsion drone
Electric propulsion technology is widely used in many kinds of vehicles in recent years, and aircrafts are no exception. Technically, UAVs are electrically propelled but tend to produce a significant amount of noise and vibrations. Ion propulsion technology for drones is a potential solution to this problem. Ion propulsion technology is proven to be feasible in the earth’s atmosphere. The study presented in this article shows the design of EHD thrusters and power supply for ion propulsion drones along with performance optimization of high-voltage power supply for endurance in earth’s atmosphere.

BACKHOE CONSTRUCTION EQUIPMENT
- 1. BACKHOE PREPARED BY VIKAS K. VERMA Roll no- 46
- 2. INTRODUCTION A backhoe, also called a rear actor or back actor, is a piece of excavating equipment or larger consisting of a digging bucket on the end of a two-part articulated arm. They are typically mounted on the back of a tractor or front loader, the latter forming a 'backhoe loader'
- 3. OPERATIONS 1. Digging action result from the drag or pull of bucket towards the machine. 2. The boom is set at desired angle 3. The hoist cable is pulled in and the drag cable is released thus moving the bucket to required position. 4. By pulling the cable the bucket is filled. 5. The bucket is lifted by raising the boom and then swinging to dumping position.
- 6. APPLICATION OF BACKHOE 1. Suitable for digging below machine level. 2. Can be efficiently used to trim or dress the surface avoiding manual effort. 3.A backhoe is designed primarily for excavation below ground and it is especially employed for trench excavation works. 4.It posses the positive digging action and accurate lateral control.
- 7. ADVANTAGE OF BACKHOE 1. It can be used for a wide variety of tasks: construction, small demolitions, light transportation of building materials, powering building equipment, digging holes/excavation, landscaping, breaking asphalt, and paving roads. 2. the backhoe bucket can also be replaced with powered the achievement such as a breaker, grapple, auger, or a stump grinder.
- 8. THANK YOU
