Jiaozuo brake

ST1SH, st2SH, st3SH hydraulic failure protection disc brake, hydraulic disc brake production zone provides us with the production of pedal hydraulic disc brake for cranes, hydraulic disc brake for hoist drum, production and sales of hydraulic cranes, etc. The production of pedal hydraulic disc brake for cranes is all in Tiejia, which is an information integration platform for the construction machinery industry, Information related to equipment in the construction machinery industry such as cranes, as well as parts of construction machinery equipment,

The hydraulic failure protection disc brake, especially the safety brake installed on the low-speed shaft at the drum end by the planetary reducer, plays an effective safety protection role for the lifting mechanism. This paper introduces the principle, performance and technical characteristics of the current advanced hydraulic disc brake and its energy-saving pump station, as well as the application of the working brake on the casting crane, which allows high frequency braking. ST3SH hydraulic disc brake

The hydraulic failure protection disc brake has large braking force and low maintenance costs. The wear of the gasket automatically compensates the ST3SH hydraulic failure protection disc brake compensation device (brake torque is stable). The hydraulic failure protection disc brake has a short response time.

Large installation tolerance, hydraulic failure protection disc brake disc end face runout: zui maximum value: ± 0.2mm. The perpendicularity deviation of the base relative to the ST3SH hydraulic disc brake: zui, maximum value: ± 4 ‰.

The Centre-to-centre distance deviation of the brake disc from the base: zui large value: ± 2.5mm.
