Compared to similar products, the HZTJ tower crane safety monitor boasts the following features:

1. The instrument is pre-loaded with over a hundred crane torque curves for easy and accurate on-site setup. The installation personnel simply select the corresponding crane model from the instrument's settings interface, and the instrument automatically retrieves the torque curve for that model from its internal FLASH memory. No additional parameters need to be manually entered; the instrument judges the torque and calculates the torque load percentage based on the model's torque curve. Once the instrument is powered on, it synchronizes the crane model, torque, and other relevant attributes to the backend service via GPRS, ensuring real-time consistency between the backend and frontend. It also synchronizes the instrument's current time with the system time.

2. Collision-avoidance Ad-hoc Network, developed through extensive research and testing by HaiZhi engineers, this self-forming network collision-avoidance system requires no additional controllers or equipment. It automatically identifies the online and offline status of instruments within the network, forms the network automatically, and offers high communication efficiency and stability. It completely overcomes the drawback where some manufacturers' controllers' power failure can lead to the entire network's failure to form. This technology is far ahead in the industry. On-site computers only need to insert a USB wireless receiver module to monitor the real-time data of tower cranes within the local area network and configure the crane parameters.

3. Utilizes robust environmental power supplies, withstands 300VAC surges for 5 seconds, and features low overall system power consumption.

4. All sensor harnesses are shielded and assembled with precision, offering electromagnetic interference resistance. Factory-set and tested initial sensor positions ensure no need for pre-positioning the trolley during installation. The installation process is straightforward and has been validated by numerous tower crane installations. Our uniquely innovative installation fixture has been granted national patent protection. The new rotating sensor significantly enhances rotation accuracy and also meets the industry's demand for multi-turn measurements. Prior to installing the tower crane, manual counting of the large turntable's teeth is no longer necessary. In the collision avoidance system, this high-precision rotating sensor ensures accurate angle measurements, thereby guaranteeing the accuracy of the anti-collision function in a group of towers.

5. The main unit is compact and aesthetically pleasing, featuring a standard 10.4-inch ultra-thin LED high-brightness display. It is well-constructed and the graphical interface system is stable, intuitive, and visually appealing. All real-time parameters are displayed in large, legible fonts with both text and graphics, along with voice alerts, ensuring drivers operate the tower crane with greater confidence and peace of mind. The appearance of the main unit has been patented by the state.

6. The debugging interface system, developed by our company, is designed for the convenient and accurate on-site debugging of instruments. This debugging interface can quickly complete various debugging tasks on-site for tower cranes, including setting of crane attributes (crane model, scale, crane number, coordinates, etc.), sensor calibration settings (hoist height calibration, trolley span calibration, rotation calibration, weight calibration, etc.), limit settings (hoist height limit, trolley near/far span limit, rotation three-cycle limit), and early warning/alarm settings (collision prevention, wind speed, tilt, torque, overload, etc.). The system has received unanimous praise from installation personnel across various regions.

7. Our proprietary soft shutdown system. The detector is equipped with a shutdown button at the lower left corner. Holding the shutdown button for 2 seconds initiates a soft shutdown, at which point the display turns off, control outputs shut down, and voice functions cease. However, the instrument's data transmission remains active, enabling real-time background monitoring. A gentle touch on the power button resumes normal display and operation of the instrument.

8. Voice Prompt System. Real human voice prompts the current dangerous conditions of the tower crane, with danger levels categorized as warnings and alarms. The voice increase button on the bottom of the screen's key pad is used to amplify the alarm volume, while the voice decrease button is used to reduce the alarm volume. The voice volume is divided into 7 levels, with level 1 being so low that it may not produce any sound.

9. Integrated safety monitoring for height, amplitude, rotation, weight, torque, wind speed, tilt, etc., with directional braking in the event of danger. The directional braking system is controlled by a weak electrical signal from the main unit, transmitted through an 8-core cable to the distribution box. Inside the distribution box, a small control box is used to control the directional braking of the tower crane, which includes: trolley forward braking, trolley reverse braking, hook up braking, hook down braking, rotation left braking, rotation right braking. Features: 1. Intelligent directional braking achieved; 2. Rational and scientific control structure; 3. Easy installation and wiring.

10. Automatic tower crane height update system. This automatic update algorithm can accurately update the real-time height of the tower crane without causing any unnecessary elevation.

11. Weld-free Installation Bracket (see installation instructions).

12. Compatible with 220V AC and 380V AC, offering a wider voltage range compatibility.

(1) In situations where there is no neutral wire on-site (i.e., only 380V AC is available instead of 220V AC), machines incompatible with 380V AC cannot be installed (most monitoring devices on the market only support 220V AC). HAI ZHI's full product line is compatible with both 220V AC and 380V AC, allowing installers to freely choose two hot wires (380V AC) to power the machine.

(2) In situations where there is a neutral wire present (i.e., 220V AC and 380V AC), machines incompatible with 380V AC must have the power cables connected correctly, i.e., one live wire and one neutral wire to form 220V AC. Incorrectly connecting the power cables will directly damage the machine. Hai Zhi Company's products do not have this issue, as they are compatible with both 220V and 380V AC, installers can freely choose two power cables to power the machine (either two live wires or one live wire and one neutral wire).

13. Fully resolves the interference issue with walkie-talkies on construction sites (some manufacturers' equipment is incompatible with walkie-talkies, affecting communication on-site and potentially product sales).

14. Industry-independent, high-precision, easy-to-install stroke sensors.

(1) High detection accuracy

(2) There are some situations where the installation space is narrow, and traditional DXZ stroke sensors cannot be installed. However, our compact sensors can be perfectly installed in such cases.
