Usually not. Hoist brakes face gravity-driven risk and must prevent load drop, so their safety requirements are typically stricter. Travel brakes (trolley or bridge travel) primarily control horizontal motion, inertia, and positioning accuracy; their failure consequences can still be serious, but the physics differ. As a result, travel brake sizing often focuses more on stopping distance, deceleration comfort, wheel/rail adhesion, and duty cycle rather than pure static holding torque against gravity.
That said, travel brakes on outdoor gantry cranes can become safety-critical under wind loads or sloped tracks. In those cases, additional holding requirements may apply, and a separate storm securing device (rail clamp or storm brake) is often mandated.
To choose correctly, define the travel worst-case: maximum speed, maximum load (including crane mass), rail slope, wind force, and emergency stop expectations. Then verify that the brake can handle both torque and thermal load at the expected stops per hour. Always align with the crane OEM’s design and local standards.
