Product Overview
The ZLT-WD Series Inclined Plane Stability Test Device is a professional instrument for assessing the stability of tabletop or floor-standing electrical appliances. Compliant with IEC60065 Clause 19.1, IEC60335-1 Clause 20.1, IEC60601-1 Clause 24.1, and IEC60950 Clause 4.1.1, this device simulates tilting scenarios to ensure appliances do not tip over unexpectedly. Available in four models (ZLT-WD1, ZLT-WD2, ZLT-WD2D, ZLT-WD3D) to suit different load and operation needs, the series supports an MOQ of 1 unit, payment via T/T, shipping from Guangzhou Port, and a lead time of 20 days. It is a staple for home appliance, medical device, and IT equipment manufacturers prioritizing user safety.

Product Features
Flexible Model Selection
The series offers four models to match diverse testing needs:
ZLT-WD1/ZLT-WD2: Manual rotation for lightweight appliances (<50kg/<80kg) with compact tables (600mm/800mm diameter).
ZLT-WD2D/ZLT-WD3D: Electric rotation (1 rpm) for heavier appliances (<80kg/<120kg) and larger tables (800mm/1000mm diameter), reducing operator effort.
Precise Angle Control
All models support an inclination range of 0~30±1°—the critical threshold for stability testing per international standards. The integrated angle measuring instrument ensures real-time, accurate angle monitoring, eliminating guesswork.
Durable Construction
The table board and supporting frame are made of high-strength steel, enabling safe testing of appliances up to 120kg (ZLT-WD3D). Hinged base plates and threaded spindles (with handwheels for manual models) ensure smooth, stable incline adjustments.
Wide Standard Compliance
Compliance with IEC60065, IEC60335-1, IEC60601-1, and IEC60950 means the device is suitable for testing home appliances (e.g., microwaves), medical devices (e.g., ultrasound machines), and IT equipment (e.g., printers).
Application
The ZLT-WD Series is widely used in industries where appliance stability is non-negotiable:
Home Appliance Manufacturing: Testing refrigerators, washing machines, and microwaves to ensure they do not tip over when tilted (e.g., by children or accidental bumps).
Medical Device Industry: Verifying the stability of portable medical equipment (e.g., infusion pumps, diagnostic scanners) to prevent accidents in hospitals.
IT & Office Equipment: Assessing monitors, printers, and servers to ensure they remain stable on desks or racks.
Regulatory Testing Labs: Conducting compliance tests for clients to meet global safety certifications (e.g., CE, UL).
FAQ
Which model should I choose for a 100kg industrial printer?
The ZLT-WD3D is ideal—it supports a maximum load of <120kg and has a 1000mm table diameter (sufficient for large printers). Its electric rotation (1 rpm) also simplifies testing.
Can the inclination angle exceed 30°?
No. The device is calibrated to 0~30±1°—the range specified in IEC60065, IEC60335-1, and other standards. Exceeding 30° would not align with regulatory requirements for stability testing.
Is the power supply customizable for 110V 60Hz regions?
Yes. The standard power supply is 220V 50Hz, but we offer custom configurations (e.g., 110V 60Hz) for regions like North America or Japan. Please specify your needs when ordering.
How does the manual rotation mode work?
Manual models (ZLT-WD1/ZLT-WD2) use a threaded spindle with a handwheel. Turning the handwheel adjusts the table’s incline from 0° to 30°, with the angle measuring instrument displaying the current angle in real time.
