- February 7, 2026Uneven braking or judder on overhead and gantry cranes is typically caused by inconsistent friction contact or mechanical looseness. Common…
- February 7, 2026Unstable voltage at the brake coil can create a cascade of issues. If voltage dips, an electromagnetic brake may not…
- February 7, 2026Selecting the wrong brake power supply box or rectifier can cause serious reliability and safety problems on cranes. If the…
- February 7, 2026A DC electromagnetic brake that pulls in weakly usually points to an electrical supply or air-gap issue. On overhead crane…
- February 7, 2026On overhead and gantry cranes, electro-hydraulic thrusters are often used to release drum (block) brakes against spring force. If the…
- February 6, 2026Insufficient thruster stroke means the brake may not fully release, partially release, or fail to achieve the intended clearance. The…
- February 6, 2026It can be either, and the fastest way to diagnose is to separate “power delivery” from “mechanical movement.” First, verify…
- February 6, 2026A dragging brake creates continuous friction during motion, causing heat and rapid wear. Typical symptoms include unusually hot brake housings…
- February 6, 2026Load slipping after brake application indicates insufficient holding torque or unstable friction. Common causes include worn or glazed linings, oil/grease…
- February 6, 2026To prevent load drift (creep) on a VFD-controlled hoist, the brake must set only when the motor is truly producing…
