\u200b1. Product Introduction<\/strong><\/h3>\n

\"WTZ-A20\u200b
\n\u200bWTZ-A20 lifting capacity limiter<\/strong>It is the \"intelligent safety scale\" installed for equipment such as electric hoists and wire rope cranes. It integrates the controller and sensors into a palm-sized integrated device, specifically monitoring to ensure that the hoisting weight does not exceed the standard. This thing is designed and produced in accordance with the national standard GB12602. It has been used on construction sites for over a decade. Its greatest feature is its compact structure, simple installation, and extremely accurate accuracy - with an error of less than 51t to 3T, which is even more precise than the electronic scales in the market.<\/p>\n

\u200b2. Main functions<\/strong>\u200b<\/h3>\n

\u200bThree measures to safeguard the bottom line of safety<\/strong>. Real-time monitoring of the hoisting weight (you can tell if it has exceeded the limit by looking at the 0.56-inch digital tube). When it exceeds the limit, the red alarm light flashes blinding, and it is equipped with a 60-decibel buzzer (as noisy as when a washing machine is spinning dry), which will immediately cut off the power to protect the equipment. The most practical feature is that it can replace the old A50\/A60 models. Electricians do not need to modify the wiring when changing the installation; just plug it in and it can be used.<\/p>\n

\u200b3. Core advantages<\/strong>\u200b<\/h3>\n

\u200bThe experienced masters all praise it for being worry-free<\/strong>. It can be installed by yourself. The Settings only require three keys (set\/Shift\/Add\/subtract). An electrician in a warehouse in Zhengzhou reported that two units were assembled in half a small time. Before leaving the factory, each machine undergoes a \"triple security check\" : freezing into an ice block at -20\u2103, baking in a 60\u2103 oven, and a 95% humidity sauna to ensure it won't break down for ten years. Although it looks just like a bar of soap, it is more reliable than security guards in critical moments. Last year, when the steel wire rope at a construction site was about to break, it shouted to the police and saved the situation.<\/p>\n

\u200b4. Technical parameters<\/strong><\/h3>\n

\"Technical\u200b
\n\u200bThe hardcore indicators are right here<\/strong>It won't freeze in the cold winter of Northeast China (working as usual at -20\u2103), and won't be damaged by the scorching heat of Hainan (stable as a mountain at 60\u2103). It has a dust and water resistance rating of IP65 (not afraid of getting wet in the rain). It can be driven with 220V voltage, consumes less electricity than a light bulb (< 30W), and makes an alarm sound as loud as 60 decibels (which can be heard even in the adjacent equipment room). The control signal is straightforward and forceful - power is cut off when overloaded, and it is managed by the output of the switch quantity.<\/p>\n

\u200b5. A slender figure<\/strong><\/h3>\n

\"Dimensions\"\u200b
\n\u200bEven more delicate than a mobile phone<\/strong>The controller is 130mm high and 70mm wide, while the sensor is slimmer and only 22mm thick. The installation is particularly convenient. Just drill two holes in the wall and it can be hung (the accessories come with a bracket). Pay attention to the panel: the \"Settings\/Shift\" key on the left adjusts the parameters, the \"Add\/Subtract\" key on the right changes the threshold, and the red alarm light in the middle is even more dazzling than the fire alarm light.<\/p>\n

\u200b6. Golden Partner Sensor<\/strong><\/h3>\n

\"Weight\u200b
\n\u200bWTY side-pressure sensor<\/strong>It is its \"sharp eyes\". It is directly fixed to the back of the instrument with bolts, and the two raised installation columns are clamped at the force-bearing points of the steel wire rope. This design is ingenious in three aspects: First, the metal casing is resistant to impact and won't be damaged even if the hook hits it. The second is that the sensing sheet is attached to the steel wire rope, responding to weight changes in milliseconds. Thirdly, it has a fully sealed structure and is durable even in workshops where iron powder is flying.<\/p>","protected":false},"excerpt":{"rendered":"
