Overturning plant is not a RIDDOR - It tends to happen to a fair degree on sites and I queried this myself. The lifting equipment refers to cranes etc when used for lifting rather than driving really.
From The schedule:
Lifting machinery, etc
1 The collapse of the overturning of, or the failure of any load-bearing part of any -
(a) lift or hoist;
(b) crane or derrick;
(c) mobile powered access platform;
(d) access cradle or window-cleaning cradle;
(e) excavator;
(f) pile-driving frame or rig having an overall height, when operating, of more than 7 metres; or
(g) fork lift truck.
The giuidance is as follows
Lifting machinery (paragraph 1)
105 The definition covers the
collapse of any of the machinery or equipment listed, the
overturning of any such machinery or equipment or the failure of any load bearing part of it, whether used for lifting goods, materials or people.
It does not cover the failure of ancillary equipment such as electric operating buttons or radius indicators.
106 The phrase ‘mobile powered access platform’ means any platform where the movement of the platform itself is powered, and not necessarily the movement of its supporting vehicle. Power elevated platforms mounted on manually moved vehicles are included. Fixed or mobile tower scaffolds are not included.
107 Incidents involving cranes must be reported irrespective of the nature of the work being done, and reports must not be restricted to those involving lifting and lowering. For example, a collapse or overturning when a machine is being used for drop balling must be included.
108 A ‘pile-driving frame or rig’ includes a bored piling rig or a percussion piling rig comprising substantially a crane with a jib, normally mounted on crawler tracks, which has been adapted by the addition of pile-driving parts.
The implication is (red highlights is that it is specific lifting equipment) an excavator for example would have check valves and an SWL indicator if it was used as lifting equipment. Your skid steer almost certainly (although I stand to be corrected) does not.
Hope this helps
