It is necessary to calculate the parameters of the hydraulic cylinders of the scissor lift
It is necessary to determine the force of the hydraulic cylinder, the working stroke, the length of the cylinder in the folded state, the distance for the placement of the cylinder. The rest is in the attachment.

Good afternoon. I will carry out the necessary calculations without considering the friction forces in the bearings and linear guides. These forces will depend on a number of factors that will be determined during the design process of the assembly. Although I assume that they are already known to the client...

Good afternoon. I will perform the calculation in Solid. I will show the acting force regarding the stages of the cylinder extension. I will provide the dimensions of the hydraulic cylinder - in the folded state and stroke.

Good morning! I want to work with you. Are you only interested in 1 calculation? If you are ready to work, message me privately, I am looking forward to it.
Develop a motor control system based on aCAN bus network, including: Selecting and specifying commercially available PLC hardware and related components. Developing the control software for operating the system from aPC and atablet (or adapting existing software to meet the system requirements). Preparing complete engineering and manufacturing documentation required for the production of the control system. A key requirement is that the maximum communication distance between the controller and the PC or tablet must beup to 100 meters. The main motor parameters, as well as the preferred/recommended hardware components, will be discussed and agreed upon during the project.
It is necessary to develop the design of an ergonomic chair/suspension for a worker who works standing for long periods during the repair of wooden pallets. The chair must be attached to the carriage of the ceiling rail system and move with the worker within the working area. The main goal is to partially relieve the load on the legs and back, while the worker's legs predominantly remain on the floor. Key requirements: designed for a user weighing approximately up to 100 kg with the necessary safety margin; adjustability of height and body support level; comfortable transition between standing, semi-sitting, and sitting positions; quick and safe release of the worker from the chair; ability to rotate around a vertical axis; the chair should not restrict the movement of arms and legs; the design should not interfere with a separate carriage with a winch for lifting pallets; provide an independent safety element or another solution against falling; parts must be available for manufacturing from steel, straps, and standard components. Expected results: Several options for the chair concept. Selection and refinement of the optimal option. 3D model of the design. Drawings of parts and assemblies with dimensions. Mounting scheme to the suspension system carriage. List of materials and ready-made components. Strength calculation of the main loaded elements. Files in STEP and PDF formats for further prototype manufacturing. I am looking for a specialist with experience in mechanical engineering, industrial design, ergonomics, or the development of suspension equipment. Preference will be given to a contractor who can not only create a visualization but also prepare a technically sound design for manufacturing and testing. Detailed dimensions of the rail system, photographs, and my developments will be provided to the selected contractor. The project is related to human safety, so the final design must undergo verification by an engineer and testing before use. Important condition regarding patents: There is a similar suspension system from the company Standing Ovation. Its product can only be used as an example of an already known solution, but its design, layout, and operating principle must not be copied. It is necessary to develop an independent technical solution that will have significant structural differences and will not replicate features protected by existing patents of Standing Ovation. I will provide the contractor with the found patent documents for review. During the development, it is necessary to: analyze the known product and propose another way to support the body; not copy the shape of the chair, frame, suspension, adjustment mechanism, and mounting scheme; prepare a brief description of the main technical differences; create a comparison table of the new solution with the Standing Ovation design; provide for the possibility of further patent verification and patenting of the own design. The contractor is expected to deliver a technically independent design; however, the final legal check for patent purity will be conducted by a separate patent specialist.
I have several ready-made samples of steam fireplaces, including a model that serves as a reference for quality, design, and functionality. The task is to develop a proprietary product under our own brand based on the analysis of existing solutions. Main tasks: complete technical analysis of existing samples; disassembly of the structure and components; determination of the operating principle of all units; preparation of technical documentation; creation of a bill of materials (BOM); selection of alternative suppliers for components; cost evaluation of production; development of the concept for our own product; preparation of a plan for transitioning from prototype to mass production.
Develop a control program (G-code) for a CNC milling machine for cutting parts from a solid blank using the nesting method (optimal packing). Initial data: — 3D models of parts in the format you need — Material of the blank: polystyrene — Size of the machine table and blank: 1200×1200×150 mm — Machine: three-axis milling (to be discussed) — Diameter of the cutter: to be discussed — Number of axes: 3 Requirements for the result: — Optimal placement of parts with minimal material waste — Correct allowances for tool diameter (radius compensation) — Technological bridges (tabs) to hold parts during cutting — Order of passes: rough pass → finishing — Post-processor for the specified machine controller — G-code file + screenshot of the trajectory simulation Experience that is mandatory: — Work in a CAM system (Fusion 360 CAM / Mastercam / SolidCAM / ArtCAM or similar) — Experience in nesting parts — Understanding of cutting modes and feeds for specific materials In your response, please specify: — The CAM system you are working in — Machine controllers for which you have written post-processors — An example of a completed similar work
Good evening! It is necessary to assemble a lamp using electronic components that are sold in the USA, specifically on specialized sites. If you can design the casing where these components will be inserted - great, if not, that’s fine too. The components need to be selected so that minimal effort is required for connection. Two options are needed: Option 1: A bedside lamp that can be charged via USB-C in 2-3 hours and the charge lasts for at least 100 hours of operation + battery discharge indicator + touch activation. Option 2: The same but with added Wi-Fi and connection to smart home systems like Google/Amazon Alexa and others + the ability to charge via wireless charging, so include wireless charging. Work stages: 1. Provide a list of components and connection instructions to assemble without designing the casing. 2. We assemble the model and check that it works. 3. We close the project.
