As the urbanisation process in various countries enters the stage of stock optimisation, the transformation of old districts has become an important 

issue to improve the quality of life of residents and improve the function of the city. The traditional ‘big demolition and construction’ mode is 

gradually replaced by the ‘micro-renewal’ concept, and small excavators, with its flexible and efficient, environmentally friendly and energy-saving 

features, is becoming a ‘weapon’ for the transformation of old districts. ‘for the city of fine renewal to inject new kinetic energy.

First, the old district transformation ‘pain point’ and demand

Old neighbourhoods generally have narrow space, complex underground pipelines, high density of residents and other issues, traditional large-scale 

mechanical operations are often faced with ‘can not get in, show not open, disturbing the people strong’ predicament.

The concept of ‘micro-renewal’ emphasises ‘acupuncture’ transformation in limited space - renovating local facilities, optimising the functional 

layout and preserving the historical features - and small excavators are the perfect practitioners of this concept. The perfect practitioner of this concept.

Second, small excavator: crack the transformation problem of the ‘all-rounders’.

Compact and flexible, adapt to narrow space

Small excavators (micro-mini excavators) are usually less than 1 metre in width and less than 2 metres in height, making it easy to pass through 

narrow passages, stairways or green belts in old districts. For example, when installing a lift in an old district in Guangzhou, the mini excavator entered 

the pit through the gap between the buildings, avoiding the damage to the surrounding facilities caused by traditional equipment.

Multi-conditions adaptation, multi-purpose machine

By replacing the bucket, crushing hammer, drill and other accessories, the mini excavator can complete a variety of tasks such as digging pits, breaking 

up road surfaces, pipeline laying, greening and soil turning. In the renovation of a district in Chengdu, one machine has successively completed the 

cleaning of septic tanks, ground hardening in the fitness area, and the demolition of fences, saving the cost of three sets of large equipment on site.

Low noise and environmental protection, reduce the nuisance

Small excavators mostly use electric or national four emissions engine, noise is less than 60 decibels, and can be operated at night. Hangzhou, a 

community renovation, equipment in the residential building next to the construction did not cause complaints, the residents bluntly said: ‘than the 

sound of the drill is still small.’

Precise control and protection of historical features

Fourth, the future outlook: technological upgrading and model innovation

Intelligent transformation: the addition of remote control, automatic obstacle avoidance and other technologies will further enhance the safety of 

small excavators operating in complex environments.

Green iteration: Hydrogen energy, solar charging mini excavators are expected to become a new choice for ‘zero-carbon transformation’.

Shared leasing model: For small and medium-sized renovation projects, the equipment leasing platform can reduce the cost of the construction side 

and improve the utilisation rate of resources.
