| Parameter | Typical range | Note |
|---|---|---|
| 钢轨 | QU70 / QU80 / QU100（吊车轨） | 按轮压选 |
| 轨道基础 | 钢筋混凝土牛腿/钢梁 | 承重要≥轮压×1.5 |
| 跨距偏差 | ≤ ±5mm / 全跨 | 超差啃轨 |
| 标高差 | ≤ 跨度/1000 | 两轨平行 |
| 固定 | 压板/焊接/弹性垫 | 防松动 |
Commonly used in: 厂房吊车梁、露天栈桥轨道、老厂房新增吊车的基础承重改造. Requirements for span, duty class and protection vary a lot by site — always specify against your real duty.
轨距/标高差；调轨复测。
压板松；复紧加防松。
承重不足；加固或加钢梁。
按最大轮压，QU70 起步，大吨位 QU80/QU100。
土建设计按轮压×安全系数；老厂房先检测承重。
跨距±5mm、两轨标高差≤跨度/1000。
先鉴定牛腿承重，不够则加固或降吨位。
