Compact loaders · Rated operating capacity and tipping load, lift geometry, breakout force, hydraulic and travel data, ROPS, screens and seat restraints
A skid steer loader is a compact machine with lift arms that carry a bucket or other attachment, steered by driving the wheels on each side at different speeds so it can pivot in place. Ask three things first: what rated operating capacity, tipping load and lift geometry it has with your attachments, what engine, hydraulic and travel performance it gives, and which protective structures, screens and restraints come with it.
Wheeled skid steer loaders with radial or vertical lift arms. Compact track loaders, mini (walk-behind or stand-on) loaders, backhoe loaders and wheel loaders are outside this page except where compared.
01
SANY explains that tipping load is the maximum weight a skid loader can theoretically handle before losing overall stability, determined on level ground with the machine stationary and the lift arms at a specified position, while rated operating capacity (ROC) is the safe everyday working weight, set by the manufacturer as a percentage of tipping load. It contrasts radial lift arms, for reach at low heights, with vertical lift arms, for lift capacity and stability at full height, adding that this depends on the machine model, and notes that heavy attachments use part of the capacity. [1]
SANY's SS270V data sheet lists a rated operating capacity of 1,290 kg, a tipping load of 2,580 kg, an operating weight of 4,300 kg, a 0.5 m³ bucket, vertical lift geometry, breakout forces of 28.8 kN (tilt cylinder) and 25.5 kN (boom), a 53.7 kW engine, travel speeds of 11.1 and 20 km/h, a 9.3 s raise-lower-dump cycle, 3,350 mm bucket pin height and 2,620 mm dump clearance. [2]
Editorial calculation: 1,290 kg ÷ 2,580 kg = 0.50, so the SS270V's ROC is 50% of its tipping load; ask each supplier what ratio and test standard its ROC uses, and with which bucket or attachment, before comparing machines. [2]
Give the supplier the materials and attachments (buckets, forks, augers, breakers), the heaviest loads and lift heights, dump height needed, ground and slopes, auxiliary hydraulic flow needed by attachments, travel distances, emission standard, cab type (open, enclosed, heated or air-conditioned) and operator training needs.
02
University of Wisconsin Extension's skid steer safety sheet (A4150) states that roughly two-thirds of a skid steer's weight is on the rear axles with an empty bucket and shifts forward when loaded, that overloading makes the machine front-heavy, and that ROC must not be exceeded. It says stability decreases as the loader arms rise, so the bucket should be kept low when travelling or turning, and slopes should be climbed or descended with the heavy end uphill. [3]
The sheet tells operators never to remove the rollover protective structure (ROPS), to keep side screens in place, and to use the seat belt and safety bar; it records that fatal crush injuries have occurred when people were caught between loader arms and the frame on unscreened machines. It also requires attachment locking devices to be engaged, warns never to operate controls from outside the cab, and calls for arms to be locked when repairs are made with them raised. [3]
Editorial note: ask the supplier which protective structures and interlocks are fitted as standard (ROPS, falling-object protection, side screens, seat bar interlocks, lift-arm support) and which standards they are certified to.
03
For machines used in US construction work, OSHA's subpart W brings rubber-tired skid-steer equipment manufactured after July 15, 2019 under its rollover protective structure (ROPS) rules; for that equipment, the protective frame must meet the test and performance requirements of ISO 3471:2008, Earth-moving machinery — Roll-over protective structures — Laboratory tests and performance requirements. The same subpart says a ROPS removed for any reason must be remounted with bolts or welding of equal or better quality, and that each ROPS must carry a permanent label naming the manufacturer or fabricator and address, the ROPS model number if any, and the machine make, model or series it is designed to fit. [4] Section 1926.602 requires seat belts meeting SAE J386-1969 on equipment it covers, except stand-up machines and machines without ROPS or canopy protection, while it lists specific skid-steer rules there as reserved. [5]
Editorial note: these are US workplace rules for construction use; for other markets ask which national or regional machinery rules the loader is certified to, and match them with the safety equipment listed by UW Extension above. [3]

SANY defines tipping load as “the maximum weight a skid loader can theoretically handle before losing overall stability”, set under standardized conditions; ROC is the safe working load set by the maker as a share of it. [1]
On SANY's SS270V, 1,290 kg ROC is half its 2,580 kg tipping load; ask each maker which ratio and standard it uses. [2]
UW Extension says stability decreases as the loader arms are raised, so the bucket should be kept low when travelling or turning. [3]
OSHA's 29 CFR 1926.1001(c) requires protective frames on rubber-tired skid-steer equipment manufactured on or after July 15, 2019 to meet ISO 3471:2008. [4]
