Product Overview

 Mine hoist is a large mechanical equipment. The motor drives the mechanical equipment to drive the wire rope so as to lift the container up and down in the wellbore. According to the connecting form of wire rope on the drum, it can be divided into winding hoist and friction hoist. According to the lifting rope, it can be divided into two ropes, four ropes and six rope hoist.This product uses the patented "magnetic balance" detection technology to realize the comprehensive safety monitoring of the steel overhead traveling rocket device. Real-time online monitoring of defects such as broken wires, rust, abrasion, elasticity reduction and connector tangling can prevent broken ropes and save the cost of inspection and maintenance and rope changing.

3  Transmission interface: As a safety barrier ,it is composed of the Intrinsically Safe Power and the Communication data conversion interface.The former supplies power to the latter. Communication data conversion interface transforms the CAN signal into the USB signal , which is transmited to computer.

4  Industrial computer stations on the host: from the special cabinets, industrial computers, special wire rope data processing software, printers, SMS notification module. Role for the collection and processing of data, display graphics, store data, analyze and determine the type of defect, generate test reports, print reports and text messages to inform customers.

 Product Overview

Our company is committed to continuously exceed and innovate, in addition to the following products have the following basic functions, but also based on and customer requirements to achieve more personalized features.

1  The principle of advanced：

  Based on the principle of magnetic flux balance magnetic metal material defect detection and the sensor, the influence of wire rope jitter on the measurement can be completely eliminated. The external wire breakage and the internal wire breakage can be detected as well and the movement direction of the wire rope can be measured.

2  Online monitoring, accurate positioning：

  To achieve a broken wire rope, deformation, wear and tear. Corrosion, loose stock, jumping wire and other defects of the type of real online monitoring, and accurate positioning.

3  Precise sensing：

  Can accurately measure the internal broken wire and the valley at the broken wire (broken wire in the valley may indicate damage inside the wire rope), broken wire detection sensitivity of 0.5% (LF) wire rope cross-sectional area, LMA detection sensitivity of 1%. It can calculate the cross-sectional area of the broken wire in one lay length and compare with the total cross-sectional area of the wire.

4  Non-contact measurement:

Speed sensors, testing sensors are non-contact wire rope sensor, safe and efficient.

5  Audible alarm：

  When found in a lay length of two valley broken wire, the system can automatically alarm to meet the GB / T 5972-2009 crane wire rope maintenance, installation, maintenance, inspection and scrap standard 3.5.2 --- when in a pitch Within two or more of the valley found broken wire, wire rope should be considered scrapped.

6  The degree of damage to the wire rope Comprehensive Assessment Function：

  On the wire rope partial damage degree of individual assessment, a comprehensive assessment of the remaining carrying capacity.

7  Defect intelligent search function：

  All detected defects can be found by computer software control. After setting the search target, the system automatically stops the rope when it passes the sensor. The user can find the defect within 100mm from the exit of the sensor to facilitate further inspection or repair.

8  Automatic notification：

  Alarm information, test reports can be printed and SMS notification function

9  Remote shutdown power：

  Remote operation, the software is running, the system automatically power-on, the software stops running, the system automatically power down.

10  Data will look, photo comparison：

  Realize historical data review, take pictures, contrast function, changes in wire rope operating conditions more intuitive.

11  One interface, multiple objects：

  Software interface can simultaneously show multiple wire rope detection curve, rope more, at a glance.

12  Automatic shutdown：

  The system can be based on user needs, serious damage to the wire rope, cut off the motor power, so that wire rope stop running, to ensure production safety.

13  Software self-test function：

  When the system sensor, microcontroller, interface or transmission cable and other equipment failure, automatically prompts the fault information.

14  Whole circle shows：

  User-friendly operation of the overall state of the rope rigorous control.

15  Internet of Things：

  Branch can help users to remotely monitor the running status of the rope, and the monitoring report in a humane manner to the user feedback.

16  Waterproof, dustproof, shockproof：

  Sensor with stainless steel seamless shell design, waterproof, dustproof, shockproof.

17  automatically generate test reports：

  The report covers key areas of interest to users such as defects, percentage of defects, percentage reduction in wire rope strength, and remaining useful life.

18    system software support WindowsXP and Windows7 and so on.

 Technology lnnovation

1  Adopt Canadian technology, patented product.

2  Sensor technology uses the invention patent - flux balance measurement principle. The measurement sensitivity is very high, and can overcome the influence of wire rope jitter on the measurement accuracy. The wire rope internal and external broken wires can be effectively detected.
