Excavator Boom Design

Vacuum trucks are a gigantic suction machine. The negative pressure generated within the machine is enough to suck up anything that fits the size of the suction hose, regardless of whether the material is in a solid, liquid, or gaseous state. In a practical application, these trucks are commonly used for cleaning sewage and drainage lines and even for hydraulic excavation. Although the equipment can vacuum almost anything quickly, there are several things that an operator must learn in order to utilize such equipment efficiently and safely.

Calculations were performed to determine the effectiveness of the design of the platform. Allowing for a safety factor of 1.5 times the design weight of 10kg and considering the bridge must not be overdesigned; plans were made for the bridge to fail at 25kg, 2.5 times that of the design weight. According to the calculations, the bridge would hold a load of over 15kg and experience failure at 20kg in the members. These calculations were later disproven in the testing, breaking 8kg earlier than expected, due to unforseen errors. An analysis of the bridge design and calculations has been included at the end of this report.

Mini diggers or excavators are the ideal size and manoeuverability for small as well as large spaces. They can hoe the soil, dig trenches, create post holes, grind stumps, remove and move soil along with other tasks with various attachments. On top of this, they are easy to control going in forward or reverse and there is less of a risk with them turning over in comparison to larger excavators. To use one of these in a non-dangerous manner, you need to remember the following safety precautions.

Pneumatic (pg. 36): “One of them was leaning his chest on a pneumatic drill, pressing it hard into the gravel road, and it made a loud rut-ta-tutting that echoed in the stillness of the afternoon, spitting up dirt and sprays of gravel as it dug.”

The configuration of this machine allows the operators to sit high enough up to see where they are digging at all times just for one feature. A feature such as this is especially important when the

Failure Mode and Effects Analysis is used to prospectively review a process to determine the potential for errors and potential harm. This allows prospective analysis of the care process.

A total of 35 sources were used throughout the article. Of the 35 sources, 27 of them were written in the last 10 years, which

The decision maker of the project who is going to decide to implement the provided solution is Linda Metzler, production planning manager of MRL. Her objective is minimizing the cost while keeping the reputation of the company at high levels considering the future of the company. Her decision criteria and performance measures are in detail in the next part and environment related assumptions are described in assumptions.

Work Breakdown Structure (WBS) is a tool that is used to define the work elements of a project and identify its entire scope. It is the map of the project which identifies all elements of the project and allows managers to keep track and control of it. It is made of a hierarchy which facilitates the evaluation of cost, time and performance at all levels of the project life-cycle and organization. The structure illustrates the smaller units and allows for adaptation and quick communication if there a problems which need to be addressed. Definitions of each task should be clear and avoid overlapping in

This paper explores the construction aspects of arch bridges, specifically the New River Gorge Bridge near Fayetteville, West Virginia. Arch bridges are one of the oldest types of bridges and have been used for thousands of years across the world. These structures can be constructed of stone, brick, reinforced concrete or steel and can span thousands of feet across wide rivers or deep valleys. The construction of arch bridges relies on the concept of compression and begins with the load at the top of the arch, or keystone. The New River Gorge Bridge in West Virginia was completed in 1977 and is a true engineering marvel. Its construction and existence allows drivers and cargo to traverse the New River Gorge efficiently and safely, an otherwise impassable obstacle.

At first, identifying the potential problems. Though I will pay more attention to the top three classical problems, it is necessary to analyze other potential problems in specific project by investigating similar IT projects that is “Failure” or “Success” before kicking off project. The “similar” can be explained in many aspects, such as same goals, cost, scope, same industry, background and so on. I need to investigate how such similar project fails. For example, we assume that a company want to launch an ERP projects recently. In this area, there are many companies did it before. Failure of high-profile ERP projects is common. In order to avoid mistakes that usually occurs in such IT project, it can investigate many failure projects, such as Airforce, Saudi Telecom and so on. The project failure of Airforce due to the following reasons: weak teamwork & composition and lack of top management support. The Saudi Telecom’s failure attributes to lack of top management support, inadequate of company culture, and huge system customization (Aldammas & Al-Mudimigh, 2011). As you

A work breakdown structure (WBS) will develop for this project and the WBS is based on the project charter, scope statement, and other relevant information. Gantt chart and network diagram also will be well prepared for this project. While preceding the planning stage, the resource usage cash flow report will showing the hours each person is assigned to work on each task each week. Furthermore, the probability/ impact matrix and list of prioritized risks for the project will be included in the project

A maximum time variance allowance of ±15% on the project is to be allowed. Quality Audits by the Architectural Teams and engineers are to be performed at regular intervals, and all other important information must be communicated to all managers involved in progress meetings. Health and Safety must be given a considerable amount of weighting due to the fact that the process is very labour intensive and involves high powered tools and heavy machinery.
