Budget: 10000 UAH Deadline: 10 days
The first thing I will do is calculate hardness and strength. That it did not disappear.”
Check out the outbreak:
the downward direction;
Block of rollers;
The load is 80 kg.
Transfer of loads to the wave of the reductor.
If 80 kg is the mass to raise, the dynamic coefficient should be taken into account at least 1.5. A minimum load of 120 should be accepted. (When the elevator starts, we become a bit harder.)
When you see slides and tensions, you can do a 3-D model.
If you don’t make a calculation, then you’ll publish another project because something is going to go somewhere.
Or if you exaggerate with strength - you’ll bear excessive losses because of the fact that you could have taken smaller profiles.
Budget: 16000 UAH Deadline: 28 days
Good evening . I have a great experience in modernizing non-standard equipment. ( see profile ) I will create a new model, replace the load, release a new set of drawings. Nuances of the design in the process of ordering.
Budget: 10000 UAH Deadline: 14 days
The link is broken (incomplete) assembly / there is no fixation, broken links to details/.
Repeat the model for its review.
The deadlines and amounts will be specified after possible opening the collection.
Budget: 10000 UAH Deadline: 12 days
Price indicated for the introduction of directions, the preparation of the CD (PDF+DXF), 4-5 render, schemes in composite/disclosed state

Добрий вечір. Так підйомник такий самий, у попередньому проекті не мав змоги обрати виконавця

Kostyantin Nazarenko 6 January 2024Перше, що зроблю – це розрахунок на жорсткість та міцність. «Щоб не прогиналося.»
Перевірю прогини:
-направляючої нижньої;
- блок роликів;
- площадки від навантаження 80 кг.
- передача навантажень на вал редуктора.
Якщо 80 кг це маса, яку треба підняти, - треба врахувати коефіцієнт динаміки як мінімум 1,5. Тобто розрахункове навантаження мінімум 120 треба прийняти. (коли ліфт стартує, ми стаємо трохи важчими).
Коли побачите прогини, і напруги, можна робити 3-д модель.
Якщо не зробите розрахунок, то будете публікувати ще один проект, бо десь щось гнеться.
Або якщо перебільшите з міцністю – будете нести зайві трати, через те, що можна було прийняти менші профілі.

Good day! I need to develop a project for a wardrobe for the hallway with complete preparation for ordering in ViyarPro. The following needs to be done: a project for import into ViyarPro (detailing, drilling); assembly drawing; specification. I want to independently order the manufacturing of parts from Viyara, and then find a master for assembly, so a complete set of "turnkey" documentation is needed. The design of the wardrobe should closely match the attached image. We are only making the wardrobe itself, without the niche (the niche will be made separately). Diagram with dimensions: https://docs.google.com/spreadsheets/d/1OAfscDTmeiH_2wUBwiIZkJQoxkZhV594/edit?usp=sharing&ouid=100288758852339750364&rtpof=true&sd=true If you have already completed similar projects, I would be happy to collaborate!
Welcome! We are looking for an experienced company, design bureau, or high-class specialist (architect/structural engineer) to develop a complete design project and set of working documentation (drawings) for our new attractions. We need not just a beautiful visual, but a ready technical solution that builders and installers can use to implement the project from start to finish. What will be included in the tasks (Scope of work): Concept and visualization Planning solution Working documentation (for builders) Our requirements for the contractor: Availability of a portfolio Ability to work in professional software Understanding of construction technologies, materials We look forward to your responses! Let's create an awesome project together!
Good day! We are the pharmacy network Med-service. For the premises for a pharmacy in Irpin, we need to carry out work on preparing the initial data for the development of architectural and computer design sections (AutoCAD), namely: Creating a measurement drawing of the facade and entrance group (porch) with photo documentation; Conducting measurements of the premises indicating: marks and differences in ceiling heights; marks and differences in floor levels; dimensions of window and door openings; thickness of reveals, walls, and partitions; Marking all engineering communications on the plan with references, including: electrical panels; electricity and water meters; sewer risers; water supply pipes; inspection hatches; air conditioners and other equipment; Preparing a detailed photo report. Examples of work are attached. We are ready to consider proposals for cooperation.
Need experience with SolidWorks metal doors We will discuss the terms of reference in private ................................................................
Development of a technical plan for sockets and switches based on the ready-made furniture drawing (Rivne / remotely). Hello! I am looking for a design engineer or technical draftsman to develop an electrical scheme for builders. What is available: An accurate drawing of the rooms with wall dimensions. Approved furniture and plumbing layout plan (where everything is placed). No 3D visualizations. What specifically needs to be done (Technical requirements): Socket and switch plan: Place points in relation to the dimensions of furniture and appliances. Specification by type (moisture protection): Clearly indicate the type of sockets for wet areas (for example, moisture-proof with grounding and IP44 covers for the bathroom). Calculation of power lines (cables): Highlight and specify power points that require a separate cable of increased cross-section (for example, for the cooktop, oven, powerful boiler) and separate lines for appliances like the extractor fan. Switch scheme: Consider convenient light control (three-way switches, linking to lighting groups). Result: A finished drawing in PDF format with accurate dimensions, clearances from walls/furniture, and technical notes for installers. Please indicate the cost of your work (for the entire project or per sq.m) and estimated completion time? 120 kV. Thank you!
