LWG208 Length and Angle Sensor for XCMG QAY25 Crane
Shenyang Winnings supplies the HIRSCHMANN LWG208 angle sensor as a direct replacement for the XCMG QAY25 telescopic boom, where a drawn steel rope reports boom extension and the same housing reports boom elevation. If you are sourcing an XCMG crane angle sensor for a fleet repair, the specification table below gives the published figures, and the fitment section lists what has to match the crane harness before the part is ordered.
What the LWG208 Measures on a QAY25 Boom
The LWG208 combines two measurements in one housing. A steel rope is drawn out over a measuring drum to report how far the boom has extended, while an angle sensor in the same body reports boom elevation. On a QAY25 telescopic boom those two readings are what the crane's rated-capacity limiter works from, which is why a replacement has to match both the rope range and the angle output rather than only the connector.
The figures on this page come from the supplier's published product record for the LWG208 and its four sibling models. Anything the record does not state — stock, packing, freight and price — is confirmed with the sales team rather than assumed here.
The same record is used when a fleet wants several sensors on one order: the five models share the 9–36 VDC supply and the 4–20 mA or CANopen signal options, but differ in length range, angle range and housing, so the model code has to be read off the crane before an order is raised.

The Five-Model Family in One View
The record publishes four sibling models beside the LWG208. The 360° angle range belongs to the LWG610 and LWG620, not to the LWG208.
| Model | Length range | Angle range | Housing |
|---|---|---|---|
| LWG152 | 0–27 m | −5° to +90° | Steel structure |
| LWG208 | 0–33 m | −5° to +90° | Aluminum |
| LWG321 / 322 | 0–42 m | −5° to +90° | Aluminum |
| LWG610 | 0–50 m | 0–360° | Industrial plastic |
| LWG620 | 0–14 m | 0–360° | Industrial plastic |
Where a Replacement Sensor Is Usually Needed
Fleet repair after a sensor fault
A crane that reports a length or angle fault is usually taken out of service until the sensor is replaced. The published range and signal option tell the workshop which of the five models can be fitted.
Boom work and recalibration
After a boom repair the sensor has to sit in the same position and report the same travel. The 1 m/s maximum drawing speed and the 0.25% FS length resolution are the figures the calibration is checked against.
Stock for rental and contractor fleets
Contractors and rental fleets keep one or two sensors in stock for the models they run. Ordering against the model code avoids fitting a 360° unit where a −5° to +90° unit is required.
Fitment Checks Before You Order
- Signal type: confirm whether the QAY25 harness expects 4–20 mA or CANopen before the part is picked.
- Length range: match the 0–33 m travel of the LWG208 against the boom it serves; the LWG610 and LWG620 run to 0–14 m only.
- Angle range: the LWG208 covers −5° to +90°; a 0–360° unit belongs to a different crane application.
- Cable and connector: the LWG208 uses a 3 × 0.22 mm² cable at 2 A per circuit, so the connector and cable run are checked as part of the fitment.
- Environment: IP65 and −20 to +85 °C are the figures to compare with the machine's working conditions.
None of these checks replace the crane manufacturer's own parts procedure; they are the points the sensor record can settle before an inquiry is raised.
Sourcing Through Shenyang Winnings
Shenyang Winnings Machinery Trading Co., Ltd. supplies XCMG parts to repair shops and construction contractors, with global shipping by air, sea and rail.
What the supplier states
Every order is cross-referenced against original XCMG drawings by the supplier's engineers, and genuine XCMG parts are mixed with factory-made structural components when a part is out of stock. Parts for XCMG and other crane brands can be consolidated into one shipment.
Supported XCMG models listed on the product record include the QUY50, QUY80, XGC100, XGC150, XGC260, XGC400 and XGC650 crawler cranes, the QY25K, QY50K and QY70K truck cranes, and the XR150D, XR220D, XR280 and XR360 rotary drilling rigs.
Inspection before dispatch
- Material verification for structural parts against the stated alloy specification.
- Dimensional checks against OEM technical data sheets.
- Industrial-grade sea-worthy wooden crates or steel frames for packing.
- Inquiry support for part selection, installation and commissioning.

Frequently Asked Questions
Which XCMG models does this sensor fit?
The LWG208 is listed for the XCMG QAY25 telescopic boom crane. The same supplier record also covers the other XCMG crane and rotary drilling rig families it trades in, so confirm the exact model code with the sales team before ordering.
What signal types does the LWG208 output?
The published record lists both 4–20 mA and CANopen as signal options across the family. The QAY25 harness decides which one the replacement has to match.
What length and angle range does the LWG208 cover?
The LWG208 measures 0–33 m of rope travel with an angle range of −5° to +90°. The 360° angle range belongs to the LWG610 and LWG620 models, not the LWG208.
How is the sensor protected on a crane?
The record gives IP65 protection, a working temperature range of −20 to +85 °C, and vibration and shock ratings of 30 Hz / 4 g and 30 g / 11 ms respectively.
Which cable specification does the replacement use?
The LWG208 record lists a 3 × 0.22 mm² cable at 2 A per circuit. The LWG321/322 pair uses a 10 × 0.14 mm² cable, so check the connector and cable run before substituting one model for another.
Can Shenyang Winnings support fitment and custom parts?
The supplier states that every order is cross-referenced against original XCMG drawings and that boom and attachment parts can be customised. Inquiry support is offered for part selection, installation and commissioning.
