WTL-A170 Torque limiter

​1. Product Introduction

​

​WTL-A170 Torque limiterIt is the intelligent safety control core specially designed by Weite for industrial cranes. The integrated slide rail type slot structure can be quickly embedded into the standard guide rail of the electrical cabinet, greatly simplifying the installation process. It is equipped with an internal black box data storage module, which can fully record 10 years of operation data through a USB interface, providing precise basis for accident traceability and maintenance optimization.

​2. Main functions​

​Multi-signal fusion monitoring and active protection​

• ​Global signal acquisition​
  "Synchronous processing"Two weight signals(Such as Bh force sensor) +Two Angle signals(Such as boom inclination Angle
  Independent monitoringThe height of the 2-way hook is designed to prevent overrolling(Prevent the steel wire rope from being overwound
• ​Triple security response​
  → 90% Load sound and Light Warning → 100% cut off dangerous action → 105% Emergency braking
• ​Data traceability system​
  The black box continuously records over 100,000 operation data. The CSV analysis report can be directly exported via USB

​3. Typical application configuration

​
​Safety protection plan for portal cranes​

​① Key sensor layout​

• ​Root of the boomYellow Angle sensor (for monitoring amplitude variation Angle)
• ​Fixed end of steel wire ropeSilver Bh force sensor (real-time load acquisition)
• ​Side of the drumBlack anti-overwinding switch (height limit redundancy protection)

​② Control center​

• ​Cab/Electrical control cabinetGrey main control instrument (128×64 LCD screen dynamically displays torque percentage)

​4. Core advantages​

​Ten years of verified industrial-grade reliability​

​✅ fast installation​
The slide rail clip "locks with one push", and the deployment can be completed in 3 minutes (saving 801T and 3T of working hours compared to traditional screw fixation)
​✅ safety protection​
IP64 dust and water resistance + three-proof varnish circuit board (resistant to extreme temperature variation from -20℃ to 60℃)
​✅ intelligent operation and maintenance​
Jitter delay algorithm eliminates false alarms; power-off memory retains key data
​✅ flexible expansion​
Reserve an RS485/4-20mA interface to support external connection to large screens or PLC centralized control
