Product representation
1. General idea of a warning switch about the risk of skew 1020500721 GJ-3
Switch 1020500721 GJ-3 is a key component of the safety system of heavy special equipment, designed to timely detect the threat of skewing of the machine and transmit the warning signal to the operator. It refers to sensory devices with a mechanical or electronic principle of action, adapted for operation in difficult conditions: vibrations, dust, moisture and temperature fluctuations typical of construction sites, quarries, agricultural lands and mining objects.
Unlike standard warning devices, GJ-3 is characterized by high sensitivity and accuracy of determining the angle of tilt of the technique-this allows it to respond to minimal deviations from a safe position. The main objective of the product: protecting the operator, technology and environment from accidents caused by distortion (for example, when the excavator was working on unequal soil, lifting heavy cargo or maneuvering on steep slopes). Due to the reliability and ease of integration, 1020500721 GJ-3 is actively used in the technique of brands Shantui, XCMG, Liugong and other manufacturers of heavy equipment, confirming the effectiveness of ensuring operations.
2. Technical characteristics of the warning switch about the risk of skew 1020500721 GJ-3
2.1 Work parameters and sensitivity
Sensor type: Two-axis angular sensor (along the X-axis — horizontal and Y-axis — vertical) with a mechanical trigger. Allows you to control the tilt of equipment in two planes — critically important for machines with a high center of mass (excavators, loaders).
The tilt angle measurement range is ±30° on both axes – sufficient for most types of heavy equipment in standard and difficult conditions. The maximum permissible angle for safe operation is 15°; if it is exceeded, a warning signal is activated.
Measurement accuracy: ±0.5° in the range of 0–20° of tilt. High accuracy eliminates false signals and ensures timely response to a real threat.
Response speed: ≤100 ms. Rapid activation of the warning gives the operator time to take corrective action (lower the bucket, change the direction of travel).
2.2 Electrical parameters
Supply voltage: 12V or 24V DC - compatible with most heavy equipment electrical systems (12V for light duty, 24V for larger equipment such as 20-30 ton class excavators).
Current consumption: ≤50mA in standby mode, ≤150mA in active signal mode. Low power consumption does not overload the battery.
Output signal type: Push-pull (to control panel):
Light signal: Red LED indicator (luminous flux ≥50 lm) - visible even in bright sunlight.
Sound signal: Beeper with a frequency of 1000-2000 Hz and a volume of ≥85 dB - clearly audible in the workplace, including conditions of engine noise.
IP protection level: IP67 - completely protected from dust and short-term immersion in water (depth up to 1 meter, duration 30 minutes), ensuring reliable operation in wet and dusty conditions.
2.3 Temperature and performance characteristics
Operating temperature range: -40 °C to +85 °C — adapted to extreme climatic conditions (cold winters of Siberia, hot summer days of Central Asia) without loss of functionality.
Vibration resistance: Complies with IEC 60068-2-6 - withstands vibrations with a frequency of 10–2000 Hz and acceleration up to 50 m/s², typical for the operation of heavy equipment engines.
Service life: ≥10,000 operating hours under standard conditions. Durable components minimize replacement frequency and operating costs.
