NOVATEST - Грузовые баллоны для испытаний нагрузки
The hanging balloons WWB-100 are designed to perform load tests and trials of lifting equipment (overhead cranes) or elevated structures (beams) in place of traditional weights, offering significant advantages in terms of safety, economy, convenience, and high efficiency.
Applications and Usage Areas
– Maritime and Offshore: Testing of shipboard cranes, rig cranes, winches, lifeboat davits, provision cranes, and other types of cranes.
– Energy: WWB (Water Weight Bags) balloons can be used for load testing and trials of overhead cranes in power plants and hydropower stations, as well as for offshore cranes for wind turbine blades.
– Oil&Gas: Testing and trials of rig cranes and offshore cranes due to the advantages of maneuverability and light weight.
– Heavy Manufacturing Industries: Load testing and trials of overhead cranes.
Specifications and Advantages
The WWB-100 system includes various sizes of bags complete with all the necessary accessories for conducting the load test. The balloons are designed so that the lifting system is separate from the water bag body. Therefore, the failure of any element or straps will not result in the failure of the lifting system or cause a local overload of the water bags.
The dynamometer’s output signal is digital. Parameter adjustment and temperature compensation can be managed internally. Wireless reception is through the handheld device, which receives the output from the load cell and displays the values on the LCD. Additionally, the handheld device can be connected via RS232 to a computer or a large screen.
Key Features:
– Robust construction
– Accuracy: 0.1% of capacity
– All functions and units are displayed on the LCD screen (with backlighting)
– Ability to set alarm thresholds for safety and warning applications or for the weight limit
– Long battery life with 3 standard “LR6(AA)” size alkaline batteries
– All commonly used internationally recognized units are available: kilograms (kg), short tons (t), pounds (lb)
– Infrared remote control for easier calibration (with password)
– Infrared remote control with functions: “ZERO”, “FUNC”, “PEAK”, “BKLT”, “Unit Change”, and “Power OFF”
– 3 local mechanical keys: “ON/OFF”, “ZERO”, and “Unit Change”. Low battery warning.
Wireless Load Shackles
The wireless load cell shackle allows for weight acquisition during load testing using WWB hanging balloons. The wireless load cell shackle does not require the use of linking shackles and comes with a wireless indicator.
The wireless load cell shackle is an extremely robust and well-built instrument for industrial use, serving as a standard tool for wireless load testing with universal applications. Whether used as a conventional crane weight or to measure force, it is microprocessor-controlled for precision accuracy, and calibration is simplified with the wireless handheld device.
Wireless load cell shackles are designed for lifting in various scenarios, such as cranes, winches, load testing with hanging water bags, and other applications. In combination with the wireless indicator, the wireless load cell shackle is the most reliable and straightforward method to manage load application.
Quality Certificates
The WWB-100 hanging balloons for load testing are produced with the highest quality PVC coating material, certified by SGS. Furthermore, they are manufactured and tested in accordance with LEEA 051 guidelines.
