Гидравлические ангарные ворота

A fixture for welding parts needs to be developed!!! Project description! 1. The base must be solid!! It needs to hold 5 parts! 2. It must be mounted on a rotating table!!! The table size is 1200×600; there are holes on the table for fastening the fixture with M12 threading with a grid of 200×200. The distance between the parts must be sufficient for welding corner seams using a welding robot!!! 3. The chisels must be quickly secured and well positioned!! 4. One side stop should be completely rigid (main base), from which the robot starts the program reference. The opposite stop should be movable — it can be implemented as a quick clamp (Toggle Clamp), a screw bolt, or a folding plate.5. During welding, the parts heat up. This also needs to be taken into account!

Quantity Surveyor needed for detailed analysis of a construction project We are looking for a specialist to thoroughly analyze the project documentation of a construction site and prepare a detailed list of all materials, volumes, and types of work.Main Task Based on the project documentation, a complete quantity take-off of the project must be performed, and a transparent table of all construction materials and volumes must be prepared. The initial data may include: architectural drawings — AR; structural drawings — KJ / KM; specifications; PDF; DWG; Excel files; if available — BIM/Revit model. We need not just a general construction estimate, but a maximum detailed Quantity Take-Off and Material Breakdown.What needs to be done 1. Complete Quantity Take-Off Calculate the actual volumes according to the project: concrete by grades and structural elements; reinforcement broken down by diameters; metal structures; formwork; blocks and bricks; cement; sand; gravel; plaster; floor screed; waterproofing; roofing materials; facade materials; tiles and stone; ceiling materials; door and window structures; glass; wood; paint; fasteners; consumables; other materials present in the project. The list should be formed as detailed as possible, without combining different materials into general positions. For example: Reinforcement Ø8 — kg Reinforcement Ø10 — kg Reinforcement Ø12 — kg Reinforcement Ø16 — kg Concrete B25 — m³ Concrete B30 — m³ AAC Block 100 mm — m² / pcs. AAC Block 150 mm — m² / pcs. 2. Breakdown by project sections All volumes must be structured at least by the following categories: Foundation; Structural Frame; Slabs; Walls; Roofing; Facade; Flooring; Ceilings; Doors & Windows; Waterproofing; Finishing Works; External Works; other project sections. It is also desirable to separate materials by floors, buildings, villas, blocks, or zones of the site, if the project structure allows. 3. Material Breakdown A separate table of all materials needs to be prepared in the format:SectionMaterialSpecificationUnitQuantity The goal is to obtain a complete list of materials required for the construction of the site, with actual quantities. 4. BOQ — Bill of Quantities A structured BOQ needs to be prepared separately:SectionWork ItemMaterialUnitQuantity If possible, also separate: Materials; Labor; Machinery / Equipment; Transport; Waste Allowance. The main task is to ensure the ability to see the net cost of materials separately from the contractor's work cost. 5. Excel model The final work must be provided in Excel. Desired format:CodeBuildingFloorSectionMaterialSpecificationUnitDesign QuantityWaste %Purchase QuantityUnit PriceTotal Cost Additional Task It would be an advantage if the specialist can create a template system for future projects. Our goal is to use a unified structure Cost Database for analyzing different construction sites in the future. We want to be able to compare: concrete, kg of reinforcement, and materials per 1 m² of construction; cost of structures per 1 m²; materials for one room; materials for one villa; cost of individual construction elements; planned volumes against actual purchases; potential material overruns. Requirements for the Specialist We are looking for a person with practical experience: reading architectural and structural drawings; working with AR, KJ, and KM; Quantity Take-Off; BOQ; construction estimates; analysis of construction volumes; Excel. Important We do not need just a rough estimate of the total project cost. We need a specialist who can break down the project to the level of individual physical materials and quantities. The main result of the work: A complete and verifiable list of all construction materials and volumes of the site that can be used for procurement, tenders, cost control, and checking for overruns. When responding, please indicate: Your experience working with AR, KJ, and KM. Examples of completed BOQs or Quantity Take-Offs. Which programs you work with. Can you work with PDF, DWG, and Revit. How you verify the accuracy of calculations. What format of source files you need. Your cost for the project or cost per m². (Project 1000m²)

Project Description:I am looking for an electronics engineer for a paid technical consultation on repairing network equipment.Problem Summary:There is a 4-channel GSM-VoIP gateway GoIP4. The device has started to go into a cyclic reboot (the relays click every 2 minutes, it does not accept calls, and it resets authorization).What has already been checked:The power supply has been replaced with a known working one (12V/2A) — the problem persists.SIM cards have been removed and checked — the symptoms are the same without them.The problem is 99% likely to be in the hardware (internal power circuit on the board, degraded capacitors, or a burnt-out DC-DC converter).What is required from the contractor:Consult on typical issues with this board and suggest which power circuit elements should be checked first with such symptoms.Important: If you are located in Cherkasy (or are willing to accept the board via Nova Poshta), we can arrange for physical diagnostics and re-soldering of components as part of this project.Please respond if you have experience in component-level repair of motherboards, routers, or similar telecommunications equipment.

The type-C must match the hole on the step model : It should look impressive for the model + don't forget about the monitor output! Best on black textolite And to avoid the obvious impression that it is not working :) (for the average user) Show me the board in the case

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.
