Brake device of 12 ton gantry crane
Brake device is related to the crane’s safety and service life, thus it is essential to choose a suitable brake for lifting crane.
General standard brake device has electric hydraulic block brake, electromagnetic block brake, disc brake, the band brake. It is wise to consider the type, specifications, using place when choosing a brake device, some check and test are also necessary.
Choosing brake type is mainly according to crane’s standards and practical needs. For example, the standards have following requirements, lifting mechanism and luffing mechanism must be equipped with close-type brake, travelling mechanism or rotating mechanism can choose close-type brake.
As for the using place, if the room is enough, block brake, band brake or arm disc brake is available; if the room is restricted, the shoe type brake or clip-on disc brake is ok. Environment is another important factory, for places with strict requirement of oil leakage, electromagnetic brake or pneumatic brake is suitable. For metallurgical place with high temperature, just choose brake with higher insulation class, such as electric hydraulic brake or metallurgic type electromagnetic brake.
When the brake is used at lower or higher temperature, especially for electrical hydraulic brake outdoors, pay attention to change the corresponding brand of hydraulic oil. Not using electromagnet brake in places full of much iron filings and dust. Prevent dust coming into the electromagnet gap, because it can influence the electromagnet suction.
For special or important situation, it is necessary to add functions according to practical needs. For lower temperature, just take electric hydraulic push heater. If there is strict standards about the conversion process of starting and braking, just install travelling switch to observe the brake state of opening and closing. For tough condition that is difficult to maintain and adjust, just add brake clearance equal device and the friction abrasion automatic compensation device. Installing manual brake device so as to open the brake by person under special condition.
