Im an ole Canadian crane mechanic and we called them Friggen BRAKES !

When it comes to cranes , there is no name for most of the "stuff " we work with .?

Its a Black Art and full of mystery and very little government regulation or training for newbies .

The thing is that big stuff is used to lift things but no thought was put into the weakest point , the cable , and the Friggen BRAKES !

Dont worry , i haven seen a hoist yet that is not fail safe .

When is the last time you heard of a crane losing its load ???

I am not a mechanic, but have worked around them for years and was a rigger for an overhead factory crane back in the day.

I figure we have brakes to stop the trolley, the gantry, and the lift.

Listening to my HSE guru, it sounds like a War and Peace length novel has been written by OSHA describing the brakeing systems with several names included for each function.

Normally it's called hydraulics thruster brakes.

There are different types of Brakes used for E.O.T Cranes such as Electro Magnetic Shoe Type Brake, in this brake there is solenoid type plunger which pulls the lever which in turn closes brake liners fitted on the brake drum shoes . Brake Drum is mounted on the motor shaft. Other is similar brake but lever is operated by electro hydraulic thruster and is called Electro Hydraulic Thruster Brake. This brake gives slow release of the brake so smooth starts and stops are achieved.

I worked on a few cranes that used worm gears to drive the hoist. As You know the worm gear will turn the spur gear but not visa versa thus stopping the hoist in any position. My to cents worth.

Without knowing the drive type on your equipment, all anyone can do is speculate.

Good post, we can call it lowrider Bicycle or Hydraulic Brake.

Thanks for sharing this.
