Why do some cranes require dual brakes on the hoisting mechanism?
Dual brakes (redundant braking) are used when the risk level is high and a single brake is not considered sufficient for safety. On many …
Read moreHow do I select a crane brake using motor power, speed, and gear ratio?
Motor power and speed are useful starting points, but you must translate them into torque at the brake location. First compute motor torque from power …
Read moreIs the safety factor for travel brakes the same as for hoist brakes?
Usually not. Hoist brakes face gravity-driven risk and must prevent load drop, so their safety requirements are typically stricter. Travel brakes …
Read moreWhat safety factor should be used when selecting a crane hoist brake?
Safety factor is the margin between the brake’s rated torque and the maximum torque your hoist may demand in real conditions. For overhead and gantry …
Read moreHow do I calculate required hoist brake torque for an overhead/gantry crane?
Hoist brake torque must be sufficient to safely hold the maximum load and handle the worst-case stopping scenario. Start by determining the load …
Read moreWhat does “spring-applied, power-released” mean in crane braking?
“Spring-applied, power-released” describes a brake design where mechanical springs apply braking force by default, and external power is used only to …
Read moreWhere are electromagnetic motor brakes typically used on overhead cranes?
Electromagnetic motor brakes are commonly used as compact hoist motor brakes or auxiliary brakes on smaller overhead cranes, wire rope hoists, chain …
Read moreWhat’s the difference between dynamic braking and static holding?
Dynamic braking refers to slowing or stopping a rotating system while it is moving. It requires the brake to absorb kinetic energy and convert it into …
Read moreAre electro-hydraulic disc brakes better for high-duty hoisting?
In many high-duty hoisting applications, electro-hydraulic disc brakes can provide performance advantages, especially related to heat management and …
Read moreCan industrial brakes be used for emergency stopping only?
Yes—many brakes are intended primarily for emergency stopping and holding, especially in fail-safe configurations. In such systems, routine speed …
Read moreHow do I prevent overheating in high-duty-cycle braking?
Overheating is usually the result of too much braking energy over time. Prevent it by verifying both torque and thermal capacity during selection. …
Read moreWhere are electro-hydraulic drum (block) brakes commonly used on cranes?
Electro-hydraulic drum (block) brakes are among the most common crane brakes because they combine strong torque output, reliable fail-safe action, and …
