7. NOTE Tipping load capacities with pallet forks are considerably less than buckets for the following reasons a The bucket capacity is rated at maximum curlback which shifts the load center back for better stability The forks are maintained at a level position which shifts the load center forward for less stability b The bucket calculations are obtained with the loader on a level surface With the pallet forks the loader is tested at various degrees of slope The load center of gravity is further out with the pallet forks than with bucket This moves the center of gravity of the loaded vehicie forward and reduces stability ANSI 56 1 1975 is a lift truck rating specification with 24 inch load center of gravity Aug 84 Litho in U S A 30 200 10 60 90 125 Skid Steer Loaders DIMENSIONS CSM304 Specifications are in accordance with IEMC standards Dimensions are with standard tires and 35 inch earth bucket 60 or 47 inch utility bucket 90 or 56 inch earth and foundry bucket 125 60 90 125 Overall Height Lift Arms Raised 124 75 in 3169 mm 125 in 3175 mm 146 25 3715 mm Height to Hinge Pin max 95 25 in 2419 mm 98 in 2489 mm 108 25 2749 mm Overall Height without Roll Gard 51 in 1295 mm 54 in 1372 mm 59 88 in 1521 mm D Overall Length w Bucket 95 75
