SZGHTECH designs and manufactures a complete range of handling and palletizing robot arms for material handling, machine tending, stamping-line transfer, carton and bag palletizing, and heavy-duty aluminum ingot stacking. Every SZGH palletizing robot and SZGH handling robot is a 4-axis industrial robot built for one thing above all: cycle time and unattended uptime. With wrist payloads from 10 kg up to 180 kg and reaches from 1,000 mm to 3,100 mm, this lineup covers the entire spectrum — from a compact CNC machine tending robot loading a small lathe, through a 100 kg carton palletizing robot on an FMCG line, up to a 180 kg heavy-duty aluminum ingot palletizer in a smelting plant. Every model ships with the SZGH-developed controller, CE certification, and a 48-hour global spare-parts guarantee. Get a free quote and engineering consultation within 24 hours.

Choosing the right handling or palletizing robot comes down to five decisions:
1. Handling, stamping, or palletizing — what's the primary task?
If the robot spends its time loading a CNC machine or an injection molder, choose a compact 4-axis handling robot (SZGH G1000-B-4). If it transfers blanks between presses on a stamping line, choose a stamping-line handler (SZGH B1500-C-4). If it stacks finished cases, bags, or drums onto a pallet, choose a dedicated palletizing robot (SZGH B2100/B2300/B3100). If workflow is genuinely mixed, the SZGH B1850-3C-4 covers both stamping and light palletizing in one robot.
2. What's the payload — and did you count the gripper?
Include the case, bag, or part plus the gripper (vacuum, mechanical, or magnetic) plus a 20 % safety margin. Typical grippers weigh 5–15 kg for cartons, 10–25 kg for bags, and 20–40 kg for heavy ingot / drum handling. A 25 kg carton with a 10 kg vacuum gripper needs at least a 50 kg palletizer — the SZGH B2300-E-4 fits.
3. What's the pallet pattern and reach requirement?
Measure from the robot base to the farthest corner of the largest pallet. Standard EUR/CHEP pallets (1,200 × 800 mm) at floor level from a robot on a 500 mm plinth typically need 2,000–2,300 mm reach. Dual-pallet coverage without a shuttle requires 2,300+ mm (SZGH B2300-E-4). Super-heavy ingots on a 3,000 mm × 3,000 mm floor plate need 3,100 mm (SZGH B3100-G-4).
4. What's the throughput requirement?
Standard SZGH palletizers deliver 1,000+ cycles per hour on typical mid-range mixed loads. For lines above 1,500 cycles/hour, add a robot or upgrade to a dual-arm cell. Cycle rate scales inversely with payload — a 100 kg palletizer runs slower than a 30 kg one.
5. How much does a palletizing robot cost?
A complete SZGH palletizing robot cell — robot + controller + gripper + safety fence + pallet infeed conveyor — typically prices USD 25,000 – 65,000 depending on payload and pattern complexity. Handling robots start lower (USD 15,000 – 30,000). Heavy-duty 180 kg palletizers run USD 55,000 – 85,000 with full integration. SZGHTECH issues line-itemized quotes within 24 hours.
1. 4-Axis Parallelogram Geometry
All SZGH palletizers use the mechanically optimal 4-axis parallelogram design — wrist stays vertical through the entire motion, minimizing wear and maximizing cycle rate compared to 6-axis alternatives repurposed for palletizing.
2. Integrated Cabinet Design
The handling models (SZGH G1000, B1500-C, B1850-3C) ship with electrical cabinet integrated into the base — no separate control box, no extra floor space, and up to 40 % faster installation.
3. Full Payload Range Under One Roof
From 10 kg CNC tending robots to 180 kg aluminum ingot palletizers, one supplier, one controller, one training program. Standardize your factory on SZGH and cut cross-training time.
4. SZGH-Developed Controller (100+ Patents)
Every robot runs the SZGH controller with palletizing-specific pattern software — mixed pallet patterns, interleaved layers, slip-sheet insertion, and vision-guided stacking all built in. No third-party pattern-software license.
5. 48-Hour Global Spare-Parts Dispatch
Critical spares (servo motors, harmonic drives, gripper valves) ship from Shenzhen within 48 hours to 126 countries — because a stopped palletizer stops the whole line.
6. Factory-Direct Pricing
Robots ship directly from our 20,000 m² Shenzhen and Dongguan factories. Typical price 30–50 % below Japanese/European brands at equivalent specifications.
Q1: What's the difference between a handling robot and a palletizing robot?
A handling robot is a general-purpose 4-axis robot that transfers parts between machines, conveyors, or fixtures — typically 10–30 kg payload with 1,000–1,850 mm reach. A palletizing robot is a purpose-built 4-axis parallelogram-geometry robot optimized for stacking cases, bags, or drums onto pallets at 1,000+ cycles per hour — typically 50–180 kg payload with 2,100–3,100 mm reach.
Q2: How much does an SZGH palletizing robot cost?
A complete palletizing cell (robot + controller + gripper + safety fence + infeed conveyor) typically prices between USD 25,000 and 65,000 depending on payload and pattern complexity. Heavy-duty 180 kg cells run USD 55,000 – 85,000. Compact handling robots start around USD 15,000. Free line-itemized quote available within 24 hours.
Q3: Why is the SZGH palletizer 4-axis instead of 6-axis?
Palletizing requires only 4 degrees of freedom (X, Y, Z, and wrist rotation) — the case must stay flat throughout the motion. A 4-axis parallelogram design is mechanically simpler, faster, cheaper, and more reliable than a 6-axis robot repurposed for palletizing. It also delivers higher cycle rates for the same payload.
Q4: Can SZGH palletizing robots handle mixed pallet patterns?
Yes. The SZGH controller ships with a pattern editor that supports mixed layers, interleaved orientations, slip-sheet insertion, and mixed-SKU pallets. Vision-guided pattern learning is available as an option for high-mix e-commerce fulfillment.
Q5: What is the maximum payload SZGH offers?
The SZGH B3100-G-4 is the largest, with 180 kg payload and 3,100 mm reach — designed for aluminum ingot, heavy chemical drums, and steel coil. Custom higher-payload versions (up to 300 kg) are available on request.
Q6: Can an SZGH handling robot tend a CNC lathe or milling machine?
Yes. The SZGH G1000-B-4 is purpose-built for CNC loading and unloading. It integrates natively with SZGH CNC controllers (via EtherCAT) and works with any third-party CNC via digital I/O handshake. Turnkey CNC + robot integration is available as a single package.
Q7: What throughput can I expect from an SZGH palletizer?
Typical throughput: 1,000+ cycles per hour for medium-carton palletizing on the SZGH B2100-F-4, 800+ cycles per hour for heavier bags on the SZGH B2300-E-4, and 400+ cycles per hour for super-heavy ingots on the SZGH B3100-G-4. Exact rate depends on payload, pallet pattern, and infeed timing.
Q8: Are SZGH palletizing robots CE certified?
Yes. All SZGH palletizing and handling robots carry CE certification (EN 60204-1:2018, EN ISO 12100:2010, EN ISO 10218-1/2). Test reports and certificates available on request.
Q9: What's the ROI of a palletizing robot vs manual palletizing?
Typical payback: 12–20 months for a single-shift operation, 8–14 months for 2-shift, and under 8 months for 24/7 operation. Beyond throughput, palletizing robots eliminate lifting injuries (a major workers' comp cost) and deliver consistent pallet quality (fewer rejected loads in transport).
Q10: Does SZGH offer palletizing robot installation and pattern programming?
Yes. Three service tiers: (1) self-install with video guides and pre-loaded standard patterns, (2) remote-guided installation with engineer video call for custom patterns, (3) on-site installation and full pattern programming by SZGH engineers. On-site service available in 17+ countries.
