Financial Report

Below is the cost breakdown for the crane including profit and labour to create the crane:


The Cost to buy a Crane will be £1200.00

For Just the Joints the cost will be £600

To Rent the crane will cost £100 per week

Prices are excluding VAT because it is for humanitarian use.

The Cost is if the crane will be fabricated in the UK, when built abroad the cost will come down and when components are bought in bulk the price will also come down.

Patents will be taken out to protect the pulley system which will be our trade secret stopping people from copying our design.

Tender Proposal Intro

ECS is a company dedicated to helping the people and the environment. We specialise in making affordable, dependable products for you the customer. Our latest product is a crane created to help save many lives by clearing rubble in the event of a disaster such as an earthquake as seen in Haiti.

Our crane will allow the user to pick up and move rubble over a distance meaning that people trapped underneath can be rescued. It will also be easy to disassemble into small pieces which will allow it to be put into the back of a Land Rover for ease of transport into the crisis area.

The crane shall be made of a mixture of wood and metal. We have chosen to make the majority out of wood because of the overall reduced weight and cost of the material. By having a lighter material the crane will be easy to carry short distances without having to disassemble it first; being able to move faster means more people can be saved.

Due to the likely-hood that there will be a lack of power in the area the crane will use hand-powered pulleys and cranks in order to move the rubble. This again helps cut down on the complexity and ultimately the cost of the finished product and means that there is less to go wrong which in such a critical environment is a key factor.

The simple design of the crane means it can be produced both rapidly and at a low cost providing the best possible value for you. Furthermore it is quick to assemble and easy to use ensuring many people can be trained in its use as quickly and as easily as possible.

As an added bonus and to make up for the trees that are cut down we will plant 10 trees for every crane you buy which in turn will reflect well on you.

ECS, rebuilding your world.

2 TONNE CHAIN BLOCK

We have chosen the 2 Tonne Chain Block, because it is small lightweight and portable. We have chosen 2 tonne for the same reasons why we chose 3 tonne on the strap as its better to be on the safe side. The chain block also includes mechanical load breaks, hardened alloy steel chains.

Available from Metals4U at the price of £47.91 per unit

Double Thickness Duplex Sling 3 Tonne 4m

We have decided to use the double thickness sling 3 tonne 4m, This was chosen this because the design specification said the crane should be able to lift 1 tonne but just to be in the safe side, it was decided that we would rather be over than under.

The sling also has reinforced Becket eyes at each end which will give greater strength where the pulley is attached.

Final Concept Idea

For our final idea we have settled on a type of gantry crane. The problem with a tower crane is that the stresses involved would be very large which would lead to increasing costs and difficulties as we did more to ensure that the design would work.

A gantry crane on the other hand cane be made of far more lightweight material which decreases the cost and the stresses can be easily calculated and compensated for.

Idea Evaluation

Whilst evaluating the idea we noticed that the lifting arm wasn't long enough to lift the load without substantially more force. Without a longer arm the current idea would require more force with the crane than without. With a longer arm we can use the principles of leverage to the point where 1 or 2 people can lift the load without the need for weights. This would make the design cheaper and more effective.

Further Ideas

Expanding on ideas already put forward I drew up a sketch detailing both how the crane would work and how the crane would be disassembled in order to fit it into the back of a Land Rover.

This Crane is purely mechanical to prevent any problems should there be a lack of power, which in an earthquake devastated area is rather likely.
