Airship Test Winch 1500kg DC Brushless Motor Battery Load & Length Sensors | KLD

A high-performance winch purpose-built for airship experiment testing, equipped with height and force sensors for accurate rope payout and recovery. The DC brushless VFD motor and onboard high-capacity battery pack remove the need for external power. Load and length sensors feed an LCD display with real-time data, and the roller-lined rope outlet supports 360° payout.

Application Scenarios and Applicable Boundaries

- Airship experiment testing — controlled payout and recovery of tether rope during airship tests.
- Sites without mains power — the onboard 48 V battery pack supports operation where no external power supply is available.
- Continuous test duty — the battery pack supports up to 4 hours of continuous operation (per case configuration).
- Real-time test records — load sensor and length counter provide live rope force and length readings on the LCD.

Boundary: Sensor ranges, battery capacity and drum capacity are matched to the experiment. Standard configuration is not intended for personnel lifting. Confirm test load, rope length, sensor range and site conditions before ordering.

Features Benefits

No external power needed — the DC brushless VFD motor runs from the onboard battery pack and offers energy-saving operation.
Higher transmission efficiency — the K-series gearbox transmits power efficiently and withstands high-load duty.
Real-time test data — the LCD displays live readings, monitoring rope force and length during the test to support experiment accuracy.

Standards Testing and Quality

The company operates an ISO 9001 quality management system. CE conformity documents (LVD, EMC) are available for applicable configurations on request. Classification certificates (e.g. LRS / BV / ABS / DNV GL) can be arranged as an optional item for marine applications.

Factory testing follows the approved technical specification for each configured unit and may include: no-load run, rated-load operation, brake function, limiter function and control verification. Available documentation may include dimensional drawings, electrical diagrams, inspection records and functional test results, depending on project scope.
