These capacities can be lifted 360 with the undercarriage in the transverse position. Capacities in the longitudinal position of the undercarriage (+/ 1 ) are specified over the steering axle with the stabilizers raised and over the rigid axle with the stabilizers down. Indicated loads comply with the ISO 67 standard and do not exceed 7 % of tipping or 87 % of hydraulic capacity. A 924 C HD Litronic Log Loader
