Hong Kong’s First Five-axle Heavy Recovery Vehicle
The EMSD always keeps pace with the times. We have taken the lead in introducing the first five-axle heavy recovery vehicle in Hong Kong for the Transport Department (TD) to strengthen the heavy vehicle recovery capability in future new government tunnels (e.g. the Scenic Hill Tunnel along the Hong Kong Link Road of the Hong Kong-Zhuhai-Macao Bridge), the existing bridges in Tsing Ma Control Area and other existing tunnels with a view to expediting the removal of heavy vehicles obstructing road traffic due to traffic accidents. The first batch of seven five-axle heavy recovery vehicles has successfully been accepted and handed over to the clients.
The body of the new five-axle heavy recovery vehicle is mainly made of light weight aluminum alloy. Equipped with the Euro VI environmentally friendly engine, the vehicle also has a new fifth axle providing it with extra loading capacity and bringing the total loading weight to 46 tonnes. This allows the vehicle to carry out suspended towing or direct towing for a broken-down heavy vehicle, such as container truck, crane truck and heavy special purpose vehicle, with a single axle weight up to eight tonnes or total vehicle weight up to 70 tonnes. To tie in with the actual environment of major bridges and tunnels in Hong Kong, the first, second and fifth axles are power-steered simultaneously, enabling the vehicle to manoeuvre in narrow spaces dexterously. Besides, the design of combining recovery and lifting functions can help quickly clear up the road and tow away the broken-down vehicles for resumption of normal traffic.
Flexible deployment of vehicle fleets plays a critical role in case of emergency recovery. Therefore, in designing heavy recovery vehicles for TD, EMSD has standardised the specifications for light, medium and heavy recovery vehicles, so that they can be operated with greater flexibility under different space constraints for bridges, control areas and tunnels. This also helps users of TD and various regional operators grasp and adapt to the characteristics of government recovery vehicles more easily. We will actively promote this new recovery vehicle design in the transportation industry so that both public and private fleets can work together to enhance the efficiency of vehicle recovery and to shorten the recovery time required for incident handling, thus bringing convenience to the public.
