How to choose a more suitable brake
-
Normally Closed vs. Normally Open
Most cranes use normally closed brakes. In this design, the brake automatically engages under the force of a mechanical spring when power is off or the mechanism is not operating, and only disengages when power is restored. This is an important safety design to prevent heavy objects from falling during unexpected power outages.
-
Classification by Structure: In addition to the most common drum brake, there are also band brakes and disc brakes, depending on different design requirements.
-
Brakes play three key roles in cranes:
(1) Support function: reliably holding heavy objects in the air;
(2) Stopping function: slowing the moving mechanism down to a stop as required;
(3) Dropping function: controlling the descent of heavy objects at a stable speed.
Important principles of selection
Helping you make a more suitable choice
Safety is the primary principle
the brake is a key safety component of the crane. When selecting a brake, it is essential to ensure its reliability and the necessary safety factor. This is especially true for cranes used in dangerous situations such as lifting molten metal, where the regulations are even more stringent.
Emphasis should be placed on compatibility
the selected brake must be compatible with the crane's performance parameters, mechanical characteristics (such as inertia), and specific operating environment. Its compatibility with other crane systems should also be considered.
Hopefully, this information will help you systematically understand crane brake selection. If you could share more specific application scenarios (such as crane type, tonnage, or special operating conditions), I might be able to provide a more targeted analysis.
