Crane Slip Ring

Introduction

The Crane Slip Ring is mainly installed on the slewing center, which is used for the mutual transmission of power and signals between the crane on and off the car.

At the same time, the slip rings of this application series are generally used in dusty and bare working environments, and the current and size are large. The slip rings also need to withstand special requirements for high shock resistance and low temperature resistance to ensure reliability and long working life.

Features

1. Compact structure, easy installation, suitable for long-term work

2. The product has high reliability and can adapt to the long-term work of the crane.

3. Aluminum alloy shell, high protection level (IP67 or IP65) can adapt to the dusty crane and the exposed slip ring working environment.

4. Alloy brush structure, precious metal (silver-to-silver) contact, excellent electrical conductivity, low signal transmission loss, and enhanced product reliability and service life.

5. High anti-vibration structure design, adapt to the high vibration working environment of the crane.

6. Special design for low temperature resistance, stable work: -30℃---+80℃.

Effect

The Crane Slip Ring is the center of the rotary system of the crane truck, located in the center of the turntable. The effect of the relative motion of the boxes. Only with the application of swivel joints, cranes can emphasize high performance in their work.

Working principle

The main Crane Slip Ring consists of the stator and the rotor. The stator is bolted to the chassis bracket, where a dark oil circuit and an oil hole on the outer edge of the lower part of the ring groove are formed, and the oil pipe is connected to the hydraulic pump and the oil tank. The rotor can be rotated together with the turntable through the pull-out frame. The rotor is provided with oil holes corresponding to the oil ring grooves of the stator, and the oil holes are respectively communicated with the oil return valve of the main distribution valve and the oil discharge passage of the hydraulic motor through oil pipes.
