Equipment Manufacturing - Factory Floor

About Us

To build industrial equipment that is safe by design, serviceable by the people who own it and documented well enough to outlast the project team that delivered it.

Who We Are

About Our Company

JR Hydraulik AB is an industrial equipment manufacturer building process machinery, material handling systems and automated production cells for plants that cannot afford downtime. Our work starts with a detailed requirements review covering throughput, product characteristics, washdown or hazardous area needs, utilities and operator access. Engineers then develop solid models and fabrication drawings, our shop builds and assembles the machine, and our controls team wires, programs and tests it before it ships. We build to customer specifications, to our own proven designs, and to print for original equipment manufacturers who need a dependable second source with consistent quality records.

Operating from Katrineholm since before 's peak demand cycles, JR Hydraulik AB keeps design, welding, machining, painting and assembly under one roof. That integration shortens lead times, tightens tolerances and makes accountability simple, because the people who engineered the machine are a short walk from the people who built it. We maintain traceable material certifications, qualified welding procedures and documented inspection plans, and we keep a service group available after startup so your maintenance team always has a knowledgeable partner when a question comes up on the plant floor.

Equipment Manufacturing - Assembly Line

Core Capabilities

  • Equipment calibration and maintenance records are kept current and auditable.
  • Annual management review sets measurable objectives for the following year.
  • Public separation and traffic management are planned before equipment arrives.
  • Work is inspected against the written specification, not against habit.
  • Client complaints are treated as quality data and reviewed monthly.
  • Pre-task hazard assessments are completed on site, by the crew doing the work.

Our Mission

To be the manufacturing partner plant managers trust with their critical-path machines, through honest lead times, disciplined quality control and engineering that solves the actual production problem.

Our Advantages

Why Clients Choose Us

Witnessed Factory Testing

We run your machine with your product or a close substitute before it ships, so problems are found in our shop where fixing them is fast and inexpensive.

Safety Built In From Sketch

Guarding, lockout points, emergency stops and risk assessments follow recognized machinery safety practice from the first concept, which avoids expensive retrofits at your site.

Design And Build Under One Roof

Engineering, welding, machining, finishing and assembly share one facility, so design questions get answered at the machine rather than through a chain of emails and change orders.

Responsive Lifetime Support

Configuration records and a dedicated service group mean the machine we built a decade ago can still be supported with the right parts and the right advice.

Documentation You Can Use

Manuals, electrical schematics, pneumatic diagrams and spare parts lists are written for the maintenance technician who will read them at two in the morning, not just for the submittal binder.

Traceable Materials And Welds

Mill certificates, welder qualifications and weld maps are retained with each job. If an auditor or insurer asks how a structure was built, the answer is on file.

Technical Documentation

As-builts, manuals, inspection logs and condition reports are delivered as part of close-out, in a format your staff can actually use.

Safety As Operating Practice

Written work plans, hazard assessments and public separation measures are produced for every site, not pulled out when an inspector arrives.

Subcontractor Discipline

Where specialist trades are engaged, they work to our safety and documentation standards and we remain the single accountable party.

What We Do

Custom Machinery Design & Build
Step 01

Custom Machinery Design & Build

Engineered-to-order machines developed from your process requirements, including mechanical design, structural analysis, drive and motor selection, pneumatic and hydraulic circuits, and safety guarding. We deliver stamped drawings, bills of material and operating manuals, and we review the design with your operations and maintenance staff before any steel is cut.

Request a Quote
Pressure Vessels, Tanks & Skids
Step 02

Pressure Vessels, Tanks & Skids

Fabrication of process vessels, storage tanks and pre-piped equipment skids using qualified welders and written welding procedures. Skids ship with instruments mounted, piping pressure tested and wiring terminated to a junction box, which cuts field installation time and reduces the number of trades your site must coordinate.

Request a Quote
Machine Retrofit & Rebuild
Step 03

Machine Retrofit & Rebuild

Mechanical rebuilds and control upgrades for aging equipment that still has sound structure. We inspect frames, gearboxes and bearings, replace obsolete controls, add modern guarding, and return the machine to service with documented performance data that justifies the investment against the cost of a new unit.

Request a Quote
Controls, Automation & Panel Building
Step 04

Controls, Automation & Panel Building

Control panels built to UL 508A practices with PLC and HMI programming, motor control centers, safety relays and network integration. Our programmers document logic, simulate sequences before shipment and train your operators on the screens they will actually use, including alarm handling and recovery from a stopped cycle.

Request a Quote
Conveyor & Material Handling Systems
Step 05

Conveyor & Material Handling Systems

Belt, roller, chain and screw conveyors, transfer stations, accumulation tables and lifting equipment sized for your product weight, line speed and sanitation needs. We integrate sensors, variable frequency drives and safety interlocks, and we lay out systems so operators and forklifts can work around them without improvised workarounds.

Request a Quote
Build-To-Print Manufacturing
Step 06

Build-To-Print Manufacturing

Repeatable production of your machines and assemblies from customer drawings, with first article inspection, controlled revisions and lot traceability. We review prints for manufacturability, flag tolerance stack-up and material concerns early, and maintain documented work instructions so the fifth unit matches the first.

Request a Quote
Factory Acceptance Testing & Commissioning
Step 07

Factory Acceptance Testing & Commissioning

Witnessed factory acceptance tests run against an agreed protocol, followed by on-site installation support, startup and operator training. Punch list items are tracked to closure, performance is verified at rated throughput, and the final handover package includes as-built drawings, test records and recommended spare parts.

Request a Quote
Spare Parts & Field Service
Step 08

A factory acceptance test is a documented run of the finished machine in our shop against an agreed checklist, covering function, safety circuits and performance. Attendance is optional but strongly encouraged, because your operators and maintenance staff can raise issues while changes are still simple.

We keep configuration records for every machine we build, so we can identify exact components and supply wear parts, replacement assemblies and technician visits long after the warranty ends. Preventive maintenance agreements are available and can be scheduled around your planned shutdowns.

Yes. Many plants standardize on specific PLC platforms, drives, motors and sensors to simplify spare parts. Tell us your approved list during requirements review and we will design around it, noting any cases where another component would perform better.

We perform a risk assessment during design and apply recognized machinery safety standards for guarding, interlocks, emergency stops and safety-rated control circuits. Final requirements also depend on your site and insurer, so we confirm expectations with your safety team during the approval stage.

Final requirements also depend on your site and insurer, so we confirm expectations with your safety team during the approval stage.

We offer both. Options range from supervision of your own riggers and electricians to full installation, wiring termination and commissioning. We recommend including at least startup support, since early operation is when small adjustments make the biggest difference.

Both. We build to customer prints with controlled revisions and first article inspection, and we design machines from process requirements when you do not have drawings. For print work, we review the package for manufacturability and raise questions about tolerances, materials and finishes before quoting.
