Product Overview
MOEORW-6860 herringbone ladder spread limiting strength testing machine is developed in compliance with DL/T 2157-2020, DL/T976-2017, DL/T1476-2023 and other power industry standards. It is specially designed for static load preventive test on the spread limiting structure of electric power herringbone ladders to judge whether the ladder meets safety test standards.
The equipment adopts an integrated all-in-one structure, with built-in control operation box to save laboratory space. It uses servo motor pulling steel wire rope for horizontal spreading loading, and electric lifting support for ladder fixing. The whole system consists of static load test bench and main control console, matched with complete test fixtures. The built-in Linux core control software runs on Windows 10 touch screen terminal, supports Ethernet data interconnection, automatic test operation, real-time force curve display, result judgment and thermal printing of test reports, which realizes full-automatic standardized preventive test of power safety ladders.
Application
Core Application Scenario
Preventive static load test on the spread limiting connecting structure of insulated herringbone ladders and metal herringbone ladders used in power live-line operation, to verify the tensile strength of ladder spread limiting device and eliminate hidden dangers of ladder opening failure during live operation.
Target Users
1.Power supply bureaus, power transmission & transformation maintenance workshops
2.Live-line operation tool testing centers of power grid companies
3.Third-party power safety tool inspection institutions
4.Manufacturers of insulated ladders and electric safety work tools
Supported Test Standards
1.Integrated Compact Structure Built-in operation control box, integrated frame design, electric ladder support bracket, light overall weight, effectively saving laboratory layout space.
2.High-precision Servo Loading System Servo motor drives steel wire rope to complete horizontal spread loading; adjustable speed and stroke, force resolution up to 0.5N, force measurement accuracy less than ±1%, stable and uniform loading.
3.Multi-layer Safety Protection Design Equipped with holding brake, mechanical hard limit, photoelectric induction limit and 160° full-surround protective mesh; abnormal force or displacement triggers automatic emergency stop with warning light reminder to avoid test safety accidents.
4.Intelligent Touch Control Software 15.6-inch touch screen operation interface, simple visual operation; built-in standard test parameter templates for herringbone ladder spread limit, automatically matching standard tension and holding time; support custom force value for special tests.
5.Complete Data Management Function Real-time display of force-time curve, automatic judgment of pass/fail after test; support thermal printing of test reports, historical data storage, query, page turning and deletion, compatible with upper-level data center via Ethernet.
6.Low Noise & High Automation Electric lifting and horizontal pushing without manual adjustment; low operation noise during long-term test; support automatic cycle test and manual independent lifting/pushing operation for debugging.
7.Multi-standard Compliance Fully meets DL/T power industry test standards and GB electrical equipment safety standards, specially calibrated for power safety tool preventive test.
