We are seeking an engineer to develop an automated lift system for a mobile shipping/storage container such that when the container is at rest, an automated lift system would raise nested walls to create a second story for the container, but when in motion, the expansion walls would rest within the unit, please see the illustration in the attachment. We specifically are looking for a designer who can aid with creating a mechanism that ensures stability, safety, and simplicity.
Specifications.
--Est. Size, in compact stage: 8’ x 8’ x 20’
--Est. Size, in lifted stage: 8’ x 16’ x 20’
--Weight: less than 4000 lbs
--Payload, Main Unit: no less than 15000 lbs
--Payload, Upper Unit: no less than 3500 lbs
--Material: steel frame with laminated sidings
--Power Supply, main: 110VAV
--Power Supply, alternative: 12VDC
--Durability: no less than 3000 times of operation
--Safety and stability:The whole unit should be hermetic, heat-insulated, and be able to withstand strong wind gusts. The units may be deployed on unpaved ground, the main and side units should be able to keep even when the terrain is slightly uneven.
Notes:
--This job can be broken down into four steps, and will progress if/when we are satisfied with the completion of each step:
1.Propose possible mechanisms to be used.

We are requesting interested candidates to present their idea by November 20. After we review all proposals, our team will vote for the winning submission. The result will be posted here, and the job will then be assigned to the winning designer.
Hello Sir, i have 9 year experience. i can do any kind of 3d graphics works. i have attached some of my best works in my profile kindly check it .if my work satisfy your needs then pay me and i am sure it will you can check my ratings, that will be a great if you give me a chance to provide you the best work in Freelance at affordable price......Thanks
I am a mechanical / mechatronic engineer, I have completely understand your requirements and I have the technical knowledge to make it happen. I will try my best to submit you proposal according to your requirements, please message me in order to get in touch. Thanks.
I'm going to use in my elaboration 4 hydraulic telescopic cylinders. This cylinders possess a large stock of stroke length. Flow Divider in hydraulic circuit of hydraulic pump unit will provide synchronous work of of cylinders. Hydraulic pump unit possible to equip with two drives – main and alternative.
Hello sir. I am an experienced engineering professional and I have designed and developed many heavy engineering equipment for various industries like mining, crushing, transport, processing etc.. For this project i can develop the complete system including the entire mechanical structure and mechanism, hydraulic power pack system and PLC/Relay logic board .
I have a very elegant solution for this problem and i can provide you with a very good quality work.
As specified i will make a preliminary proposal of my idea and you may review it and take a call to suit your interests.
I'm an experienced mechanical engineer. I've designed similar mechanisms in the past, like a perpetual machine, a portable escalator, and a water-based motor for boats.
If I'm selected to be the design engineer, I will include in my proposal different designs to let you have the option to select a design based on comparison of parameters.
Please feel free to message me, if you'd like to discuss further details.
