This is the shocking moment bungling crane operators dropped a lorry, sending it toppling down a hillside.

The jackknifed truck had crashed and overturned onto its side before the emergency services arrived to recover the vehicle in Shandong, China.

But the size of the shipping company's fully-loaded lorry made the procedure more complex, and two truck-mounted cranes were needed to lift it back onto its wheels.

Aerial footage captured by Mr Li shows the two machine operators hoisting the wrecked truck into place following a road crash.

But just as they repositioned the cargo vehicle, it suddenly tipped in the opposite direction and overturned for a second time.

The white shipping container box could be seen plunging down the hillside while the truck wobbled on the roadside during the bungled process on December 2.

Officials said that nobody was injured in the initial crash or the botched recovery.
