SZGH B3100-G-4 — 4-Axis Heavy-Duty Palletizing Robot for Aluminum Ingot & Super-Heavy Industrial Loads

What Is the SZGH B3100-G-4?

The SZGH B3100-G-4 is the highest-payload robot in the entire SZGH product line — a four-axis industrial palletizing and heavy-load handling robot rated at 165 kg payload with a 3,100 mm working radius. Engineered for foundry environments, aluminum ingot casting workshops, and super-heavy industrial palletizing, it combines maximum load capacity with the operational simplicity of a 4-axis architecture: fewer joints, faster palletizing cycles, and significantly lower maintenance cost than a six-axis robot in the same payload class. Its support for three mounting configurations — ground, bracket, and ceiling — makes it adaptable to the most demanding factory layouts where other robots in the B Series cannot be deployed.

Core Advantages

165 kg Payload — Highest Capacity in the Entire SZGH Product Line

At 165 kg, the B3100-G-4 sits at the top of the SZGH load capacity hierarchy across all robot families. This enables single-pick operations that would require two smaller robots or multi-cycle sequencing on lesser-payload machines. In aluminum ingot handling, 165 kg capacity means picking up to 8 standard 20 kg ingots simultaneously per cycle — a throughput level no competitor in the SZGH lineup can match.

3,100 mm Reach — Near 3.1 m Working Radius Covers Entire Heavy Industrial Cells

The B3100-G-4's 3,100 mm arm span is the longest in the B Series. In foundry and casting plant layouts, this reach bridges the gap between casting output conveyors and pallet staging areas in a single cell without robot repositioning or additional transfer stations, reducing cell complexity and potential transfer failure points.

Three Mounting Options — Ground, Bracket, and Ceiling

Unlike other B Series models which are limited to horizontal floor mounting, the B3100-G-4 supports ground, bracket, and overhead/ceiling mounting. Ceiling (inverted) mounting is particularly valuable in foundry environments where floor space around casting equipment is at a premium and overhead structural beams are available for robot anchoring. This flexibility makes the B3100-G-4 the only B Series robot suitable for overhead-suspended palletizing cell designs.

4-Axis Structure: Right Tool for Heavy-Load Palletizing

Heavy-load palletizing — whether aluminum ingots, steel billets, or dense industrial cartons — is fundamentally a point-to-point pick-and-place task in a planar work envelope. A 4-axis robot accomplishes this with two fewer joints than a 6-axis equivalent, meaning two fewer motors, gearboxes, encoders, and cables subject to wear in a harsh foundry environment. Fewer failure points directly translate to higher uptime in continuous three-shift operations where downtime cost is measured in tons of lost production per hour.

±0.2 mm Repeatability in Extreme Thermal Environments

Heavy industrial environments — particularly aluminum and steel casting workshops — operate at sustained high ambient temperatures. The B3100-G-4 is rated for 5°C–45°C ambient operation standard, with control cabinet cooling upgrades enabling deployment in environments up to 55°C. At every operating temperature within its rated range, the ±0.2 mm repeatability specification holds, ensuring consistent pallet layer alignment and stack stability across all three shifts.

Customer Case Study

By Fannie Chen, CEO, Shenzhen Guanhong Automation Co., Ltd. (SZGH) | May 2026

This is the case that matters most to me personally when I think about why we build industrial robots.

A foundry in Russia came to us. They produce approximately 8 tonnes of aluminum ingots per day — 400 standard 20 kg ingots every shift. From the moment the ingots come off the casting line, every step to the final pallet has historically been done by human hands in a workshop where the ambient temperature regularly exceeds 50°C. The plant had a severe and worsening labor problem: workers simply would not stay. Turnover was so high that the company was running perpetual recruitment cycles. And for the workers who did stay, the long-term health consequences of sustained heavy physical labor in that thermal environment were a liability the company's management team could not ignore.

When we evaluated their layout, it was clear this was a job for the B3100-G-4. The robot's 165 kg rated payload meant it could pick up 8 ingots simultaneously — 160 kg per cycle — and the 3,100 mm arm span covered the full distance from the casting output conveyor to the pallet staging zone without any need for intermediate transfer equipment. The three-mount capability allowed us to position the robot on a floor-level ground mount in their specific cell geometry.

One engineering challenge: the workshop ambient temperature in summer peaks at 55°C — 10°C above the robot's standard 45°C rating. We addressed this by upgrading the control cabinet with an enhanced active cooling system, bringing the effective operating envelope to 55°C continuous. The robot has been running three shifts continuously since deployment without thermal shutdowns.

The outcome: workers were completely removed from the high-temperature handling zone. Two operators now monitor the cell remotely from a climate-controlled station, watching status screens. The 8-ingot-per-cycle throughput comfortably met the daily production target.

But the number I think about most is not the throughput figure. It is the number of workers who no longer spend their careers lifting metal in a 50°C room. That is what this robot replaced. Not the job — the physical harm.

Frequently Asked Questions

Q1: Is the B3100-G-4 really the highest-payload robot SZGH makes?

Yes. At 165 kg, the B3100-G-4 is the maximum payload model in the entire SZGH product portfolio across all robot families including both B Series and T Series. No other SZGH robot currently exceeds this payload rating.

Q2: What industries is the B3100-G-4 designed for?

The robot is primarily designed for heavy industrial handling applications: aluminum and metal casting workshops, foundry ingot stacking, steel plant raw material handling, heavy-duty industrial palletizing (IBC containers, large drums, dense material stacks), and automotive pressed-part transfer. Any application requiring single-pick loads above 100 kg and a wide working radius is a candidate for the B3100-G-4.

Q3: Why use a 4-axis robot at 165 kg instead of a 6-axis heavy-duty robot?

Heavy palletizing and large-part transfer are planar tasks. A 165 kg 6-axis robot is significantly more expensive to purchase, requires more complex programming for palletizing tasks, and has more wear components (6 joint gearboxes instead of 4) in a harsh foundry environment. The B3100-G-4 delivers the same palletizing result with lower total cost of ownership, faster palletizing cycle times, and simpler on-site maintenance — which matters critically in a foundry where downtime costs are high and specialist robotics technicians are not always available on-site.

Q4: What mounting configurations does the B3100-G-4 support?

The B3100-G-4 supports three mounting configurations: ground mount (standard floor installation), bracket mount (elevated or tilted installation on structural frames), and ceiling mount (overhead/inverted installation on factory ceiling beams or gantry structures). This is unique within the B Series — all other B Series models support horizontal ground mounting only.

Q5: Can the B3100-G-4 operate in a foundry environment where temperatures exceed 45°C?

The standard specification is 5°C–45°C ambient. With the optional enhanced control cabinet active cooling upgrade, the system has been successfully deployed in environments with ambient temperatures up to 55°C on a continuous three-shift basis. Contact SZGH engineering to confirm specific thermal environment requirements before ordering.

Q6: How many aluminum ingots can the B3100-G-4 pick in a single cycle?

With a custom ingot-clamp gripper, the 165 kg payload capacity allows picking approximately 8 standard 20 kg aluminum ingots per cycle (total ≈160 kg including EOAT tare weight). Exact count depends on ingot dimension, gripper geometry, and cycle speed requirements — SZGH engineers will calculate this for your specific ingot specification as part of the application assessment.

Q7: What is the warranty and after-sales support for the B3100-G-4?

The robot carries a 12-month warranty from delivery. Technical support is available 24 hours a day, 5 days a week via WhatsApp, and remote diagnostics are supported through the controller network port. SZGH has authorized distributors in Russia, the USA, Turkey, Romania, Egypt, Thailand, and Mexico for local on-site service.

Q8: How does the B3100-G-4 compare to the B2300-E-4 for general palletizing use cases?

The B3100-G-4 offers 3.3× the payload (165 kg vs. 50 kg) and 35% more reach (3,100 mm vs. 2,300 mm) than the B2300-E-4, with ceiling mount support, but at a higher capital cost and lower peak axis speed due to the larger mechanical structure. For carton palletizing up to 50 kg per pick, the B2300-E-4 is faster and more economical. The B3100-G-4 is the correct choice when single-pick loads exceed 50 kg or when ceiling mounting is required by the cell layout.
