Jiaozuo brake

There are various models of electric hydraulic thrusters, but the working principle is similar, and the structure is shown in the following figure. After being powered on, the motor inside the hydraulic brake drives the centrifugal oil pump inside the hydraulic brake head, increasing the hydraulic oil pressure. Hydraulic oil transfers pressure to the piston in the oil cylinder, and the hydraulic push rod moves upwards driven by the piston to open the brake shoe of the brake.

Technical data of the hydraulic holding brake (taking the technical data of MYTl-90 electric hydraulic thruster as an example): thrust 900N, stroke 80mm, rising time 0.8s, Fall time 0.5s, power 0.25kW, 20 # engine oil, oil weight, 720 operations per hour, and the model of the supporting brake (the combination of thruster and brake can form a hydraulic holding brake).
