Recently, Weite Technology Co., Ltd. installed a set of pile driver torque limiter for Haiwei 951 pile driver. The torque of the whole machine reached the use standard and passed the customer's acceptance.

Daqiao Haiwei No. 951 was delivered from Jiangsu Jingjiang Dongfang shipyard and will hit the first hammer at Jingjiang Hengde general wharf. "Haiwei 951" pile driver is 74 meters long, 52 meters wide and 95 meters long, which is the highest pile frame in China. The length of the pile driven at one time is 82 meters plus water depth.

The ship is equipped with 125 type and 180 type piling hammers, which can insert square and circular steel piles and concrete piles with pile diameter of 1.0m to 2.5m. The use of the ship has further improved the construction capacity of deep-water foundation of offshore bridges in China.

Compared with other domestic piling boats, the "Haiwei 951" piling boat has three major characteristics: first, it integrates piling and hoisting, with a maximum lifting weight of 240 tons at a time, and can also perform a range of - 27 ° to + 25 °; Second, 18.5 ° inclined piles can be inserted and driven, and the elevation angle of pile foundation construction is the largest in China; Third, the 95 meter high pile frame can be folded three times. The pile frame after amplitude change is only 25.4 meters from the water surface and can reach any construction site in the middle and lower reaches of the Yangtze River.

The weight, amplitude, wind speed and various monitoring parameters of wtl-a700 torque limiter are accurate after on-site commissioning by Weite engineers, and have been unanimously recognized by customers. The torque limiter has the functions of real-time monitoring, dynamic display, sound and light alarm, data backup, power-off memory and password protection, and the design of the instrument itself has the advantages of strong anti-interference, friendly operation interface and strong versatility.

The micro special angle meter is composed of a potentiometer and a pendulum, which can be installed on the boom of the crane. The angle of the boom to the ground is measured by the rotation of the potentiometer driven by the weight, and the corresponding voltage value is output. The measurement accuracy is high, and the measurement range is as high as - 10 degrees to + 110 degrees. The anemometer adopts RS485 communication to the upper computer, with long communication distance and stable signal without distortion.

Through this installation, the customer has a more intuitive understanding of the torque limit of the pile driving ship, and the operator will not continue to overload the crane when the lifting curve of the crane is exceeded. The customer highly appreciated the effective guarantee of hoisting safety and personnel safety.
