Tail Lift Automatic Tripping System (ATS)

A tail lift (also called a mobile dock leveler) is a mechanical device permanently fitted to the back of van or lorry. The tail lift facilitates the workers to load or unload goods. However, unsafe operation of tail lifts can cause trapping injuries or even death. In the past few years, there were several serious accidents caused by the operation of tail lift, including

  1. Body of operators trapped by the tail lift when tail lift is closing.
  2. Foot of operators trapped by the tail lift when the tail lift is moving up.

Hong Kong Productivity Council (HKPC) proposed a Tail Lift Automatic Tripping System (ATS) to reduce the chance of injury. The system is composed of two parts:

  1. Tripping Device - It is a laser scanner to detect the obstruct when the tail lift is closing, and stop the operation of tail lift once emergency occurs
  2. Foot Protector - It is a photoelectric retro-reflective sensor to detect the foot when the tail lift is moving up from ground, and stop the operation of tail lift once emergency occurs
Service Details

HKPC provides consultancy service about ATS installation to the industry.

  1. HKPC will conduct on-site assessment to assess if the contractor is qualified to install the ATS. The qualified contractors will be listed in "List of participating contractors" which will be shown in HKPC website for public inspection.
  2. When the ATS installation is complete, HKPC will conduct on-site inspection to inspect if the ATS meet the relevant requirements. Upon successful testing, HKPC will issue a label to the truck. This label proves that the ATS of the truck is inspected by HKPC and meets the relevantrequirements.
