A crane usually needs 4 outrigger pads, corresponding to its 4 hydraulic outriggers, which are used to bear weight and stabilize the front, rear, left and right corners of the crane.
Detailed description
Question Answer
How many pads are needed? Usually 4, corresponding to each hydraulic outrigger.
Is the number fixed? Generally, cranes are equipped with 4 outriggers, so there are 4 pads. However, for some special models (such as crawler or large telescopic boom cranes), the number may increase to 6 or more depending on the specific outrigger structure.
Can more be prepared? You can prepare 1-2 more pads for backup or to deal with complex terrain (such as some soft ground requires double padding).

Scenario Suggestions
Heavy lifting (>50 tons) Consider placing 2 layers of foot pads under one leg to enhance load-bearing and ground protection capabilities
Soft ground/grass operations Add a large support plate, or first lay a large layer of plastic ground protection mats before placing the foot pads
Slope/uneven ground operations It is recommended to use adjustable pads or multi-layer combination pads to ensure the crane is horizontal and stable
