Система климатизации и полива

Need a professional engineer to calculate and design a modular trailer platform with a load capacity of 60 tons for a ready-made chassis. There are factory drawings. Changes need to be made.

It is necessary to integrate the NCS with the automatic launch system (catapult with a microcontroller) to transmit a signal to the microcontroller, which will initiate the operation of the catapult 500 meters away from it.

I am looking for a designer to prepare working drawings for exhibition stands. I need a person with experience working with composite materials, who understands their capabilities and limitations, and knows how to properly design parts for milling and production. The task is to create technical drawings, including visualizations: assemblies, sections, dimensions, fastenings, specifications, and other data necessary for the construction manufacturing. It is preferable that the candidate already has experience in exhibition stands, advertising, or decorative constructions and can offer practical, technological solutions for production. Here are some examples of the direction to move in: https://www.instagram.com/market_tablo https://www.instagram.com/crealle/ https://www.instagram.com/artefinal_brasil/ https://www.instagram.com/rahbardesign/ https://www.instagram.com/kiancogroup.cnc/ Attached photos also include samples. In the PDF - the design that needs to be tested currently. It is not guaranteed that this project will be confirmed and go into production, but I need to understand the designer's approach. In any case, the test will be paid. The working area of the milling machine is 2100*4100 (vacuum table and automatic tool change with 7 positions).

It is necessary to manufacture an aviation wing, I will provide the drawing or 3D model. I am considering materials such as: aluminum - extrusion or covered frame, carbon fiber composite materials your option.

It is necessary to design a mechanism for the remote opening of hopper lids (railway grain car) at an operating elevator. The unloading area has a roof and allows for unloading on 2 tracks simultaneously. The system must move from both sides of each track and have dimensions of 60 cm in width (there is a separation system that does not allow exceeding the specified dimensions). The system must be installed and move exclusively along the floor along the track and the movement of the cars (a suspended system cannot be implemented). The power supply is electric 380-220V, and the actuators can be either electric or hydraulic; pneumatics are not considered. The mechanisms for opening the lids have 2 types depending on the type of car, and also different locations for the locks themselves. The system must open and close the locks and have a video surveillance system for positioning the working organ that will open the hatch and move back and forth. The operator is located at a distance of 150-250 m and there is also the possibility of manual control next to the mechanism or from a remote control. I am attaching a diagram of the hangar, drawings of the aspiration layout, and analogs of the mechanism from an American manufacturer.
