Product Introduction

MOEORW-WDZ72 safety tool mechanical performance test device is independently developed by our company, fully complying with the requirements of Preventive Test Regulations for Electric Power Safety Tools (Guodian Fa [2002] No.777). It can complete all specified mechanical performance preventive tests for safety tools as required by national standards.

The equipment adopts imported display screens and core electronic components, controlled by microcomputer for full-process testing. It supports automatic generation and printing of standard test qualification certificates for filing and inspection. Besides standard power safety tools, users can customize test parameters to conduct tensile/compression tests on ropes, hoists and other lifting soft & hard materials.

It is widely applied in power, telecommunications, construction and other industries to complete mechanical performance inspection of safety and climbing tools, and also supports special impact & puncture resistance tests for safety helmets with matched helmet test bench.

FAQ (Trust-building General Questions for Buyers)

Q1: Does this machine comply with national power safety test regulations? Can test reports be used for official filing?

A1: Yes. The equipment is fully developed in accordance with Preventive Test Regulations for Electric Power Safety Tools (Guodian Fa [2002] No.777). The built-in printing system outputs standardized test certificates that fully meet the filing & inspection requirements of power bureaus, safety supervision bureaus and third-party testing organizations. All test data, force value and holding time records are traceable.

Q2: Can it test both light-load small tools and heavy lifting equipment?

A2: Absolutely. It is equipped with two independent sensors: 3kN for light climbing tools (belts, foot buckles, small ladders) and 20kN for heavy items (steel ropes, double hooks, safety helmets). Optional 50kN/100kN high-load sensors are available for extra-heavy lifting equipment testing. The two sensors can work alone or simultaneously for dual-point stress measurement.

Q3: Is the helmet test function fully equipped? Do I need to buy extra accessories?

A3: The full set we supply includes a complete helmet test bench with head form, impact hammer, puncture cone, 1m fixed drop frame and safety guard. No extra parts are required for impact and puncture resistance tests of safety helmets. The control system has built-in dedicated helmet test menus with automatic judgment of pass/fail results.

Q4: How to guarantee test accuracy? Will the sensor drift after long-term use?

A4: The sensor precision reaches 0.05 grade, and the whole machine accuracy is superior to 0.5 grade. The system has built-in zero-point and full-scale calibration functions. If zero drift occurs after long working hours, operators can complete sensor calibration via simple menu operations without professional maintenance. Each unit passes strict factory calibration before delivery with calibration report attached.

Q5: Is the operation complicated? Do workers need professional training to use it?

A5: Adopts Chinese LCD menu + intuitive membrane buttons, all test items are pre-stored in the system (safety belt, foot buckle, ladder, helmet etc.). Operators only need to select the corresponding tool model, set standard force & holding time with directional keys, then start auto-test. The operation manual contains detailed step-by-step guides, and we provide remote video operation training after delivery.

Q6: What safety protection designs are installed to avoid operator injury during testing?

A6: 1. Full closed protective door for hydraulic loading chamber, machine stops automatically if the door is opened during loading; 2. Matching safety steel wire rope to bind test pieces to prevent broken parts from splashing; 3. Auto force-loss alarm & compensation function to avoid sudden unloading; 4. Independent helmet test bench with surrounding safety guard to block falling hammer.

Q7: What's the after-sales service and warranty policy?

A7: We provide a 1-year full machine warranty (excluding consumables like printer paper). Lifetime technical support and remote troubleshooting are available. If hardware failure occurs within the warranty period, we supply free replacement parts. We can also arrange on-site installation & commissioning service for large orders.

Q8: Can we customize test parameters for special non-standard tools?

A8: Yes. The equipment supports fully customizable test force, holding time and loading speed. Apart from pre-set standard power safety tool programs, users can edit and save custom test modes for ropes, slings, special lifting fixtures and other non-standard workpieces.
