The TWZ (B) series normally open drum brake is hydraulically driven, and the horizontally installed normally open brake is controlled by foot operated hydraulic pressure
The TWZ (B) series normally open drum brake is mainly used for the rotating structure of small and medium-sized gantry cranes and tower cranes, with a manual brake device that can be used for braking in non working conditionsThe TWZ (B) series normally open drum brake is a foot operated manually operated normally open drum brake, mainly used for deceleration braking of various small and medium-sized crane operating mechanisms. The installation dimensions of TWZ products comply with JB/ZQ4388-1997 standards, while the installation dimensions of TWZ (B) products comply with German DIN15435 and JB/T7021-2006 standardsThe TWZ (B) series normally open drum brake is a hydraulically driven, horizontally installed normally open brake that is controlled by a foot operated hydraulic pump. It is mainly used for the rotary structure of various small and medium-sized gantry and tower cranes, with a manual brake device that can be used for braking in non working conditions
Compliant with standards: TWZ series normally open control block brakes, installation dimensions comply with JB/T7201-2006 standards, TWZ (B) series normally open control block brakes, installation dimensions comply with German DIN15435 and JB/T7201-2006 standards.
Main features
The interlocking equal distance device always maintains equal distance between the two side tiles during use, avoiding the phenomenon of one side brake pad floating against the brake wheel due to uneven distance.
The main swing hinge points are equipped with self-lubricating bearings, which have good transmission efficiency, long service life, and no need for lubrication during useThe brake pads and brake pads adopt a card insertion type, which is convenient and fast to replace
Usage conditions:
Environmental temperature: -20 ℃~+50 ℃
There should be no flammable, explosive, or corrosive gases in the surrounding working environment, and the relative air temperature should not exceed 90%.
Outdoor rain and snow erosion or corrosive gases and media should use anti-corrosion (based on actual reports) products
