---

BS 7121-2-3 is a part of a multi-series of British standards on code of practice for the safe use of mobile cranes, which covers its inspection, maintenance and thorough examination. 

BS 7121-2-3 gives recommendations for the pre-use checks, in-service inspection, maintenance, thorough examination (in service and following exceptional circumstances) and supplementary testing of mobile cranes, including truck cranes, wheeled rough terrain cranes, wheeled yard cranes, crawler-mounted cranes, mini-cranes and vehicle-mounted self-erecting tower cranes. 

BS 7121-2-3 on code of practice for the safe use of cranes is useful for:  

• Crane operators, users and owners 
• Construction managers 
• Health and safety executives 
• Site project managers 
• Regulators and testers 

A mobile crane is a cable-controlled crane mounted on crawlers or rubber-tired carriers or a hydraulic-powered crane with a telescoping boom mounted on truck-type carriers or as self-propelled models. They are designed to easily transport to a site and use with different types of load and cargo with little or no setup or assembly. 

BS 7121-2-3 provides guidance on the pre-use checks, in-service maintenance, thorough examination and supplementary testing of mobile cranes, including truck cranes, wheeled rough terrain cranes, wheeled yard cranes, crawler mounted cranes, mini-cranes and vehicle mounted self-erecting tower cranes. 

Use of the guidance given in BS 7121-2-3 can help protect the safety of crane operators and can also be taken as an indication of good practice on site.
