| Parameter | Typical range | Note |
|---|---|---|
| 起重量 | 0.25t – 100t(钢丝绳);0.5-35t(环链) | 环链紧凑适合低净空,钢丝绳适合大吨位 |
| 起升高度 | 3m – 30m(可定制) | 双绳比单绳提升快一倍 |
| 起升速度 | 1.5 – 8 m/min(双速) | 重级选双速定位 |
| 运行速度 | 11 – 21 m/min(跑车) | 配单梁走工字钢 |
| 工作级别 | M3 – M6(FEM 1Am-3m) | FEM 级别决定寿命 |
| 防护 | IP54 常规,IP55/防爆可选 | 防爆 Ex d IIB T4 用于易燃易爆 |
Commonly used in: 单梁起重机配套起升、工位物料转运、模具吊装、设备检修、小型仓库. Requirements for span, duty class and protection vary a lot by site — always specify against your real duty.
导绳器磨损或斜拉;换导绳器、禁止斜吊。
锥形转子制动磨损;调间隙或更换制动。
轴承缺油或超载;按手册加油、核载。
低净空、频繁轻载选环链;大吨位、长程选钢丝绳。
欧洲起重分级,1Am 轻~3m 重,决定理论工作循环寿命。
看现场气体组别,常用 Ex d IIB T4;粉尘环境用 ExtD。
可,建议双速遥控+急停,化工高温环境优先。
