Description

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.

Functions

l The entire system requires only one digital control terminal to complete all operations.

l All the measurement items are transmitted through Bluetooth or wire.

l The test results are directly displayed on the digital terminal.

l Intelligent curve analysis allows manual comparison of measurement results.

l The system can save unlimited sets of test data over the years.

l Intelligent analysis of possible risks of crane operation through changes in data.

l The brake slip can be measured at any angle below the crane, which fully guarantees the safety of operators and measuring instruments.

l No need to install the target and mark on the measured object to complete the deflection measurement.

l The instrument adopts telephoto imaging system, which can observe the measured target from a long distance.

l Speed measurement function: it can measure the lifting speed of the crane lifting mechanism.

l No wiring on site, no crane control circuit required, greatly reducing the difficulty and intensity of work and increasing safety.

l Linear motion speed measurement.

l Measurement information is automatically collected by the instrument, no manual input required.

l The instrument uses a high-precision absolute encoder to ensure measurement at any angle without affecting the accuracy of the measurement.

l The instrument uses a high-precision, high-frequency rangefinder to ensure the accuracy and real-time of the ranging data.

l Adopt dedicated intelligent digital terminal for data collection and data processing, friendly user interface and simple operation

l The host is composed of a ranging sensor and a theodolite installed on the base.
