01 / Launching accessories

Planning the launch
Check pit dimensions, bore alignment, ground stability and the appropriate launching equipment before work.
02 / Pulling accessories
Pull suitable pipes into position during piercing.
TERRA pulling accessories are designed to provide a compact connection between the piercing tool and the product pipe.
Interchangeable centring adapters allow the arrangement to be configured for different compatible pipe sizes.
When used with the appropriate pulling cable, the system can support pulling short pipes or longer coiled pipe lengths into suitable ground during the piercing operation.

Confirm pipe compatibility
The pipe material, outside diameter, connection method and pulling arrangement must match the selected TERRA equipment.
03 / Expanding accessories
Increase the bore diameter with compatible expanders.
TERRA offers expanding accessories designed for applications where the original pilot bore needs to be enlarged.
Oversized end sleeves and compatible adapters can enable a larger bore diameter to be created using the same TERRA-HAMMER in a subsequent operation.
This provides a configuration option for installations requiring a bore larger than the original tool body.

04 / Connecting accessories
Reliable air connections for pneumatic piercing.
A suitable compressed-air supply and hose connection are essential to TERRA-HAMMER operation.
TERRA's accessory information includes air hoses available in 15, 20 and 25 metre lengths.
Quick-coupling components support straightforward installation and connection without additional tools, where the correct compatible fittings are used.

Air supply matters
Compressor pressure, required airflow, hose specification and coupling compatibility should all be checked against the selected tool.
05 / Traceable accessories
Track the tool's position and depth.
TERRA's traceable piercing system uses an electronic sonde housed within a compatible KOK-LD head adapter.
The sonde works with suitable handheld radio locating equipment featuring an LCD display.
This arrangement enables the operator to determine the position and depth of the traceable piercing tool.
TERRA describes KOK-LD adapter options for compatible TU machines, including TU 080plus SK and larger configurations.

06 / Ramming applications
Specialist applications for steel pipe installation.
TERRA's manufacturer information also describes suitable TERRA-HAMMER piercing tools being used for steel pipe ramming and related applications.
Its accessory information refers to installations involving steel pipes up to 300 mm in diameter and lengths up to approximately 20 metres.
Those figures are manufacturer examples, not a universal capability for every piercing tool. The correct equipment depends on casing size, ground conditions, installation distance and required force.
