It is used for the measurement of the brake slip of crane hoisting mechanism; deflection, resilience, camber, dynamic stiffness of the crane girder; the speed and acceleration of crane and crab/trolley; Crane hydraulic cylinder inspection.
It can also be used to measure the travelling speed and braking distance of other large equipment moving parts, as well as testing deformation of large-sized objects.
The entire system requires only one digital control terminal to complete all operations.
All the measurement items are transmitted through Bluetooth or wire.
The test results are directly displayed on the digital terminal.
Intelligent curve analysis allows manual comparison of measurement results.
The system can save unlimited sets of test data over the years.
Intelligent analysis of possible risks of crane operation through changes in data.
The brake slip can be measured at any angle below the crane, which fully guarantees the safety of operators and measuring instruments.
No need to install the target and mark on the measured object to complete the deflection measurement.
The instrument adopts telephoto imaging system, which can observe the measured target from a long distance.
Speed measurement function: it can measure the lifting speed of the crane lifting mechanism.
No wiring on site, no crane control circuit required, greatly reducing the difficulty and intensity of work and increasing safety.
Linear motion speed measurement.
Measurement information is automatically collected by the instrument, no manual input required.
The instrument uses a high-precision absolute encoder to ensure measurement at any angle without affecting the accuracy of the measurement.
The instrument uses a high-precision, high-frequency rangefinder to ensure the accuracy and real-time of the ranging data.
Adopt dedicated intelligent digital terminal for data collection and data processing, friendly user interface and simple operation
The host is composed of a ranging sensor and a theodolite installed on the base.
