Brake piston for Terex BT4792

The brake piston, part number 901-00139, functions within the swing gear assembly of the Terex BT4792 crane. It applies the force required to engage the braking mechanism, which allows the operator to control the rotation of the crane superstructure or hold it in a fixed position during lifting operations.

This component is designed for use in the Terex BT4792 model. It serves as a key element in the swing system, ensuring that the rotational movement of the crane is managed effectively. By applying pressure to the brake assembly, the piston helps maintain stability and prevents unintended movement of the upper structure during load handling tasks.
