Import Boom Truck Crane Use Safe Load Indicator System — Buy in wholesale FOB from Supplier in China

The WTL-A200 Load Moment Indicator from Weite Technologies Co., Ltd is a smart weigh overload protector designed for boom truck crane applications, manufactured to comply with GB 12602-2009 Lifting Machinery Overload Protection Devices and GB/T 3811-2008 Crane Design Specification. The system measures loaded goods through a preset weight sensor and displays actual load instantly on the display instrument, triggering acousto-optic alarm when load reaches the rated threshold with switching value output shown. Weight measurement spans 0T to 400T with 0.1T resolution ability and synthetic errors kept to 5% F.S. or below. The complete system comprises sensor, connecting cable, and microcomputer host, with an RS485 output interface for data communication integration.

The system architecture separates into IP68-rated weight sensors for outdoor exposure resilience and IP64-rated monitor units for cab-mounted operation. Working voltage tolerance of AC220V plus or minus 25% accommodates fluctuating site power conditions common on construction and logistics fleets across Chinese and international job sites. Preset output contact capacity at AC220V 7A enables direct integration with crane control circuits and safety interlock systems. Operating temperature range spans minus 20 to 60 degrees Celsius with relative humidity tolerance of 90% RH at 20 degrees, reflecting design intent for year-round outdoor deployment in variable climates without enclosure modification.

Primary buyers include crane fleet operators, heavy equipment rental companies, and construction contractors managing boom truck fleets in infrastructure, energy, and logistics sectors. The system serves both retrofit installation on existing crane installations and OEM integration for new equipment builds. Importers should confirm with Weite Technologies Co., Ltd whether the RS485 interface protocol supports integration with specific telematics platforms already in use, and whether cable lengths between sensor and microcomputer host suit their intended boom configurations. Site voltage stability and local electrical codes should also be verified before finalising configuration.

Weite Technologies Co., Ltd maintains its registered address at No.6 Gangcheng Road, Free Trade Zone, Yichang, Hubei Province, China, postal code 443005. The supplier holds a harbor trust tier classification on the platform, with a recorded response rate of 0.00% and average response hours of zero, indicating either a new listing profile or limited historical engagement data through this channel at time of review. No verified turnover, employee count, or year of establishment is stated in the available profile information.

The company lists the WTL-A200 Load Moment Indicator as a crane safety product with stated compliance to two Chinese national standards for lifting machinery protection devices and crane design. The product description emphasises reasonable layout, easy installation, and simple operation alongside claimed high accuracy performance. Importers should independently verify current production status, after-sales support capability, and whether technical documentation including calibration certificates and installation manuals are provided in languages required for their destination market before committing to order.
