RollMaster 重型脚轮覆盖 RM-Medium（150–500 kg）、RM-Heavy（500–1500 kg）和 RM-Extreme（1500 kg 以上）系列，轮径从 100 mm 到 300 mm。每只支架均为焊接结构，装配前在动态测试台上完成载荷测试。
典型应用：机器搬运滑撬、模具车、重型手推车、仓储平台车，以及每个工作日都要滚动、没有停机维护窗口的设备。
规格参数
- 单只脚轮承载 500–2000 kg（地面不平整时按 4 只中 3 只承载计算以确保安全）
- 焊接重型钢板支架，镀锌或粉末喷涂表面处理
- 精密滚珠或滚柱轴承，标配注油嘴
- 每批次进行动态载荷测试
表面处理
镀锌、镀铬、粉末喷涂
| Bracket finish | What it does | Specify it when |
|---|---|---|
| Zinc plating (blue/white) | Baseline corrosion protection | Standard dry indoor use |
| Chrome plating | Hard, decorative, easy to clean | Visible / cleanroom-adjacent equipment |
| Powder coating | Custom color, good corrosion resistance | Brand colors, outdoor-adjacent use |
| Stainless steel 304 | No plating to fail | Washdown, food, medical |
| Stainless steel 316 | Resists chlorides | Salt, brine, marine air, harsh cleaning chemicals |
测试与检验
轮子同轴度与支架对中按内部 QC 标准检验；额定载荷基于 EN 12530 测试协议
| Selection factor | Rule of thumb | Effect on performance |
|---|---|---|
| Load sizing | Total load ÷ 3 (not ÷ 4) | On uneven floors only three wheels carry the cart |
| Wheel diameter | Bigger rolls easier | Larger wheels cut push force and bridge gaps |
| Tread hardness | Softer = quieter, harder = easier rolling | Pick the softest tread that carries the load |
| Bearing choice | Precision ball for manual pushing, roller for heavy loads | Bearings dominate rolling resistance at high load |
| Swivel vs rigid | 2 swivel + 2 rigid is the standard cart setup | All-swivel carts wander; all-rigid carts cannot steer |
| Floor condition | Rough floors need bigger wheels and softer treads | Small hard wheels on bad floors destroy both |
