Choosing a robot
How do I size the payload?
Start with the workpiece weight plus the weight of the gripper or tool. The farther the center of gravity sits from the wrist, the harder the same weight works the wrist, so send us your tool drawing at the quote stage and we will check the fit.
How do I check reach?
The reach in the spec table is the arm at full extension. Tool length and wrist angle shrink the usable range, so the most reliable check is to overlay your layout on the work envelope drawing (DWG). Drawings download without a login.
Should I choose a cobot or an industrial six-axis robot?
If people work close by and loads and speeds are moderate, start with an HG-C cobot. For heavy or fast processes, start with an HG-R industrial arm. Either way, whether an application can run collaboratively is decided by a risk assessment of the application, not by the robot type.
What is a SCARA robot good for?
Fast horizontal moves and insertion. The HG-S6-50 runs a standard cycle in 0.32 s (2 kg, 300 mm horizontal and 25 mm vertical, round trip). If the part has to be tilted or turned, a six-axis robot is the better fit.
What does ±0.03 mm repeatability mean?
It is how tightly the robot clusters when it returns to the same point. We test to ISO 9283, returning to five points 30 times each, and the hits fall inside a sphere with a 0.03 mm radius. It is not the same as accuracy, which is how close the robot gets to a commanded coordinate.
Planning and installation
What does the rollout look like?
Seven steps: spec review, basic design and quote, contract, build, installation, commissioning, and training and handover. The spec review pins down your parts and target cycle time, and the basic design comes with a cell layout and a quote.
How long does installation take?
A single-robot cell usually takes a few days to install and one to four weeks to commission (example). Multi-robot lines are phased around your existing construction schedule. In our Gyeongsan seat frame welding case (example), the line was running six days after installation began.
What does the site need?
A floor or pedestal that can carry the robot and the forces it creates in motion, the right power supply for the model, and compressed air if you use pneumatic tools. The HG-R12-14 and HG-R25-18 run on three-phase 380 V. Pedestal and anchor drawings come with the basic design.
Will it connect to the equipment I already have?
The HGC-7 controller talks to your line PLC over Modbus TCP, EtherNet/IP, and PROFINET, plus digital I/O. Fieldbus configuration files (EDS, GSDML) are on the downloads page.
Can I use a government grant?
Many robot adoption programs in Korea, national and local, are filed jointly by the buyer and the supplier. Terms vary by program, so send us the notice and we will prepare the datasheets, quote, and cell layout it asks for.
Safety
Does a cobot still need a fence?
The robot alone does not decide that. Whether an application can run collaboratively is set by a risk assessment of the whole application, including tooling, workpieces, and nearby equipment (ISO 10218-2:2025, ISO 12100). In Korea, Article 223 of the Rules on Occupational Safety and Health Standards requires a fence at least 1.8 m high or equivalent collision protection. Elsewhere, local rules apply.
Who does the risk assessment?
The integrator who builds the application and the employer who runs it own the risk assessment. The steps are: prepare, identify hazards, estimate the risk, plan and apply reduction measures, and record the results. We supply the safety settings and stopping time and distance data, and we review it with you from the spec stage.
Are Hangyeol robots safety certified in Korea?
Under the Korean Occupational Safety and Health Act, an industrial robot itself falls under the KCs self-declaration of safety conformity, not mandatory safety certification. Certification applies to protective devices such as safety mats and light curtains. Our robot arm declarations and other markings (ISO 10218-1, ISO 13849-1 PL d / Cat. 3, CE) are listed on the quality and safety page. This is a fictional company, so the numbers are samples.
Are inspections required after installation?
In Korea, yes. Industrial robots need a statutory safety inspection: the employer running the robot gets the first one within three years of installation and then every two years. We supply the datasheets and safety function records the inspection needs.
How do you stay safe while teaching?
In reduced-speed mode on the HGT-12 teach pendant, tool speed is capped at 250 mm/s. Use the emergency stop and the three-position enabling switch on the pendant, and work to a written procedure.
Training and support
Who do I call when something breaks?
Our service line takes calls 24/7 (+82 53-0614-2790, support@example.com). We start with remote diagnostics to narrow the cause, then send an engineer from the nearest technical center (Hwaseong, Changwon, or Cheongju) or dealer if needed.
How does remote diagnostics work?
Only during a window you approve, we pull alarm history and operating logs from the HGC-7 controller. We never move the robot remotely. We tell your team what we found and what to do next.
Where can my team get trained?
Hangyeol Academy runs three levels (Basic, Intermediate, and Advanced) at our Dalseong training center and the Pangyo Robot Lab. Basic is also offered online. Each level comes with a certificate.
How long do you supply spare parts?
For 10 years after a model goes out of production. Common wear parts are stocked at our technical centers and ship right away.
Quotes and purchasing
How do I get a price?
Pricing depends on tooling, surrounding equipment, and installation scope, so we quote each job. Send a quote request with your parts and process, and an engineer will get back to you by the next business day.
Can I see a robot in person?
Visit the showroom at our Dalseong headquarters to see robots running and test them on your own parts. Visits are by appointment. Our Seoul and Busan dealers also have an HG-C10-13 demo unit, and our Incheon dealer has an HG-M600.
Can I buy just the robot, or the whole cell?
Either. Buy the robot and build the cell yourself or with a system integrator, or hand us the whole cell, including tooling, surrounding equipment, and safeguarding. We started in 2009 building welding cells, so we do cell design through commissioning in-house.
Do you supply plants outside Korea?
Hangyeol robots work in 23 countries. Our Frankfurt subsidiary covers Europe and our Detroit subsidiary covers North America. Elsewhere, we work with 28 partners. If the same model is going into plants in Korea and abroad, we quote them together.
