The HZ21 military bridging system is deployed by China and referred to by CHIC as a 'fast bridge'. It is transported and launched over the rear of a forward control 88 cross-country truck.

Prior to launching the two-part bridge, a stabiliser is lowered on either side at the rear of the platform. The lower part of the bridge is then extended over the gap, followed by the upper part - the complete bridge is then lowered into position.

When fully extended, the 10.5-tonne (11.6 ton) two-part bridge is 21 m (69 ft) long and has a roadway width of 3.3 m; it can bridge a wet or dry gap of up to 19 m. According to CHIC, it can be deployed in fewer than 10 minutes and retracted in a similar time.

The HZ21 can handle tracked vehicles with a gross vehicle weight (GVW) of up to 60 tonnes, or wheeled platforms with a maximum axle load of up to 17 tonnes.

In many respects, the HZ21 is similar in concept and operation to the General Dynamics European Land Systems - Germany (GDELS-G) Rapidly Emplaced Bridge System (REBS) deployed by the US Army, which is transported and launched from a Common Bridge Transporter (CBT).
