The load values are quoted in tons (t) on the backhoe bucket’s load hook, and may be swung 360° on firm and even ground. Values quoted inbrackets apply to the undercarriage when in longitudinal position. Capacities are valid for 600 mm wide, double-grouser pads. Indicated loads arebased on ISO 10567 standard and do not exceed 75 % of tipping or 87 % of hydraulic capacity (indicated via #). Maximum load for the backhoebucket’s lifting eye is 27 t. Without bucket (4,30 m3), the lift capacities will increase by 3950 kg, without bucket cylinder, link and lever they increaseby an additional 1250 kg. Lifting capacity of the excavator is limited by machine stability, hydraulic capacity and maximum permissible load of theload hook.According to European Standard, EN 474-5 in the European Union: Excavators must be equipped with an overload warning device, a load diagramand automatic check valves on the hoist cylinders when they are used for lifting operations which require the use of lifting accessories.
