A brilliant powerful alternative for sensitive surfaces
The new Norcar a7545 Four-Track Miniloader has the same format and abundant equipment level as the a72, but is equipped with a more powerful diesel engine, and higher hydraulic oil flow. The machine is renowned for its durability in the most demanding environments, and the hydraulic oil flow of 66l/min accommodates a multitude of efficient tools to work perfectly. Double acting hydraulic pumps naturally come as standard. Additionally, the a7545 is equipped with dual-purpose hydraulic rear outlets.
Innovative design and advanced engineering delivers ultra-efficient four-track operation
The unique new generation Moorend Four-Track System was developed and engineered in the UK specifically to answer the perennial issues of sites with difficult topographical terrains and sensitive surfaces. The new design-technology was based on thirty-years’ practical experience in solving maintenance and operational problems on all types and makes of two-track vehicles used in the UK, Australia and the USA. The scope of this specialist knowledge is profound and our development engineers have worked on the majority of two-track vehicles used in the construction and agriculture industries. In comparison to conventional wheeled machines and two-track vehicles, Moorend’s advanced Four-Track vehicle technology is successfully delivering a new high level of operational efficiency, economy and environmental compliance.
The logical choice for multiple applications in the field
The sole reason for pursuing the concept of designing a new type of four-tracked vehicle, was to answer the perennial problems of surface damage caused by wheeled and two-tracked skid-steer machines; especially when working on unstable, uneven or sensitive ground surfaces. Tyres inevitably create deep ruts, which causes deep troughs, which then quickly transforms into a deep mud quagmire with serious run-off issues. The majority of conventional Miniloaders and heavyweight four-wheeled loader/shovels, and two-track skid-steer crawler/carriers are known to cause excessive surface-soil damage under sensitive surface conditions. Two-tracked vehicles provide a part-solution but skid-steer mechanisms generate a tremendously powerful
circulating-grinding effect, which in turn deteriorates the surface and mashes the substrate, which again can lead to run-off. Track to wheel interchangeability is another advantage for operators that want even more versatility from their a45-4T.
The proven alternative to wheeled and two-tracks
Ground surfaces in the UK vary enormously. Problem surface materials, topographical terrain characteristics and prevailing regional weather conditions, cause inefficient and expensive working conditions for machine users and operators throughout the UK. Up to now in the construction, building and farming sectors, wheeled machines and twin-tracked vehicles have been the only mini- or middleweight alternatives. These machines are selected to suit the specific type, variety and scale of work to be done; as well as the status of the local surface, topographical features, site access options and environmental constraints.
Typically, surfaces that are sensitive or unstable in the UK will include native soil-based substrates such as sand, shingle and clay; all of which are also affected by the local topography such as gradients, wetlands and water-logged areas.
Codes of practice and environment agencies
Operators and ecologists alike are seeking better traction and steerage, less surface damage and lower running costs. Authoritative government bodies such as Defra, the (Department for Environment, Food and Rural Affairs), are increasingly seeking to enforce their Codes of Practice and demand more stringent governance and compliance laws, to minimise the surface damage and run-off caused by construction machines on sensitive ground surfaces. Norcar 4-Track Miniloaders now provides a real alternative that addresses the stringent demands from Environment Agencies to protect soil structures.
