The construction materials industry is one of the most labor-intensive sectors for manual palletizing worldwide. 25–50 kg cement bags, aerated concrete blocks, and bricks are stacked by hand by thousands of workers every day. Staff turnover reaches 60–80% per year, workplace injuries are common, and output is inconsistent.
WSC palletizing robots work reliably in these exact conditions. Let's examine three of the most common industry applications.
📌 The construction materials industry is the second-largest market for palletizers globally, after food and beverage. The market for construction automation is growing at 18% annually.
Case 1. Cement Factory — 50 kg Bags
The Challenge
A cement factory produces bagged cement in 50 kg bags. Line output is 800 bags per hour. Manual crews stacked 600–650 bags/hour (4 workers), and the rate dropped to 500 by end of shift. Frequent sick days due to back and shoulder injuries.
Solution: WSC-MD60
The WSC-MD60 with 60 kg payload stacks 720–750 bags per hour consistently throughout a 12-hour shift. The stacking pattern can be programmed for a specific pallet in just 20 minutes. The robot operates 24 hours per day with maintenance stops only.
| Metric | Manual Labor (4 workers) | WSC-MD60 |
|---|---|---|
| Throughput | 500–650 bags/hour | 720–750 bags/hour |
| 3-Shift Operation | 12 workers + shift premiums | Same robot, no premiums |
| Injuries per Year | 2–4 incidents | 0 |
| Stacking Accuracy | Inconsistent | ±1 mm |
| Payback Period | — | 8–11 months |
Case 2. AAC Block Factory
Product Characteristics
AAC (autoclaved aerated concrete) blocks are fragile and require precise stacking — uneven pressure causes chips and cracks. This leads to distributor complaints and returns. Manual stacking is inconsistent and causes up to 2–3% transport damage.
Solution: WSC-MD40 with Soft Gripper
The WSC-MD40 equipped with a vacuum gripper with adjustable pressure places each block with precisely calculated force. Damaged product rate dropped to 0.1% — an order of magnitude lower than with manual labor.
💡 Cost savings on claims and returns at one AAC factory totaled $1,800/month — this alone partially offsets the robot's cost, before counting labor savings.
Case 3. Brick Factory — Multiple Package Types
Brick factories often produce several product types simultaneously: ceramic brick,clinker brick, facing brick — with different weights and geometries. For manual crews, changeover takes up to 1.5 hours. The WSC robot reconfigures in 15–20 minutes via the operator screen.

Common Questions from Factory Directors
"We have non-standard pallets — will it work?"
WSC is programmable for any pallet size and stacking pattern. If you have Euro, GOST, or non-standard pallets, we prepare a program for your specific dimensions before shipment.
"Our production is dusty/humid — can the robot handle it?"
Enclosure protection IP54 — standard for production environments. The robot is rated for dusty and humid workshops. Additional protection is available for particularly aggressive conditions.
"Do we need special foundations or installation work?"
No. The robot installs on a standard concrete floor and is secured with anchor bolts. Installation takes 1–2 days. Startup and commissioning are done remotely or on-site by a technical specialist.
