Ihimer: 3s‐skid concept skid‐steer loader

5 April 2016

3S represents a whole new interpretation of compact construction equipment and has been developed in collaboration with the University of Pisa within the framework of the funding contract R&D 2012 promoted by the region of Tuscany. The driving force behind the 3S concept is the implementation of electronic machine management to ensure “man/machine” and “environment/machine” interactions based on the reduction of emissions, on social and economic sustainability, on intelligent management of a machine or of a fleet of Skid steer loaders or mini‐excavators.

Hybrid power, reliability, speed, servo‐assisted joystick controls and compact dimensions: these are the key features of the IHIMER 3S‐SKID, ideal for working in enclosed or open spaces.

With an operating weight of 1330 kilograms, the 3S‐SKID has an operating load of 330 kilograms and a delivers a breakout force of 750 kgf.

This skid‐steer loader is equipped with a hybrid power generation system. Power is stored in a lithium ferro phosphate battery pack (Li‐Fe‐P04) 90 Ah 86 V, which provides a range of 2 hours (Ihimer standard cycle) and the auxiliary power unit is the on‐board 7 kW Worms Expert 7510X.

The 3S‐SKID can be equipped with a range of useful accessories for work in enclosed spaces or open sites: snow plough blade, pallet fork, sweeper with bucket. There are four operating modes: electrical, hybrid‐endothermic, hybrid‐mains electrical power, 7 kW site generator set.

The machine can be recharged from the mains power supply via a 16A 220‐230V 3kW power socket, or by the on‐board generator. The battery is housed under the rear hatch and is completely removable.

The four independent wheels are electronically controlled, ensuring the ability for counter rotation about each wheel, with an intelligent drive control system that manages power delivery according to the actual demand. The hydraulic pump unit has been replaced, as have the drive chains, increasing the ground clearance by 2.5 cm with obvious benefits as regards the machine's ability to travel over obstacles. During the development of the 3S system, special attention was given to ensuring a high level of protection for components against the penetration of liquids in operating conditions.

Among the main constructional features adopted to ensure maximum operator comfort and driveability are: electric joysticks, adjustable seat, sequential safety sensor (the machine will only start after sensing that the operator is seated in the driving seat and has correctly fastened the seat belt), connection of the machine in webserver, user recognition badge.

Close attention is also given to after‐sales service, with a wireless diagnostics system that can be interrogated using devices such as tablets, laptops or smartphones. 3S‐SKID can also be operated using a remote control capable of managing all the functions of the machine, without compromising manoeuvring speed, fluidity or precision. 3S‐SKID can be equipped with a GPS tracker, a clearly useful function for hire fleet management.
