B2B platform Build a system to the required length. Decide which sections carry material and which deliver it through perforations. View the complete lance and its parts list.
Read the assembly from the bottom: 1 — tip, 2 — section next to the tip, 3 — connector, 4 — extension, 5 — end fitting or further extension, 6 — packer / adapter connection. Select a number or component. Solid and perforated versions are shown side by side.
Exploded diagram, not to scale. Components shown side by side are alternative versions.
Enter the lance length and perforated zone length. Then select sections to view their specifications or change the delivery zone.
* Mining packers and couplers for the Ø21,3 mm system are available on enquiry and are not included in this configurator.
Ø13 mm: sections of 500 or 1000 mm. With 500 mm sections, the perforated length can be set in 0.5 m steps.
Turquoise: perforated sections · grey: solid sections
Select the tip, section, connector or connection to view its detail. On a phone, swipe the diagram sideways. Assembly length is the sum of section lengths; 500 mm sections are shown at half the length of 1000 mm sections. Accessories are not to scale.
Connectors are counted between sections: the number of sections minus one. The connection and tip are listed separately. The driving plug, hose and pump are worksite accessories.
The diagram and component list above show one lance. Each assembly has the same configuration.
Material exits through the side holes of the lance. The JG-NOSHOOTER tip closes its end. The position of the perforated sections defines the injection zone.
The solid lance carries material to the end of the system. JG-SHOOTER is the ejectable tip intended for this configuration.
Perforated sections with an ejectable tip: side outlets and an opening at the system end.
Wrench flats let you hold the component while tightening the connection. Place the wrench jaws on the prepared flat surfaces.
In the Ø21,3 system, the 3/8″–1/4″ adapter also has wrench flats. JG-CONNECTOR 21,3 has a different geometry and is shown separately in the diagram.
| Feature | JG Ø13 mm | JG Ø21,3 mm |
|---|---|---|
| Internal channel | Ø9 mm | Ø14,3 mm |
| Section length | 500 / 1000 mm | 1000 mm |
| Perforation | Ø3,8 mm · 16 holes/m | Ø5,5 mm · 16 holes/m |
| Joining sections | JG-CONNECTOR 14 coupling, 1/4″ female thread | JG-CONNECTOR 21,3, 3/8″ male threads |
| Starting section | JG-END-PER for the fixed tip; JG-CONNECT / JG-CONNECT-PER for the ejectable tip | JG-PER / JG-CONNECT with a male thread for mounting the tip |
| Extension | JG-CONNECT / JG-CONNECT-PER | JG-CONNECT-S / JG-PER-S, female threads at both ends |
Drive the lance in sections. The JG-HAMMPLUG driving plug protects the threaded connection and transfers impacts to the lance. For use with a hammer drill, it connects to a JG-HAMMPOD adapter matched to the tool holder: SDS+ or SDS-MAX.
Before driving, tighten the components correctly and fit the driving plug. Do not strike an exposed thread or drive a loosely assembled system: this can damage the threads. Use the wrench flats for tightening.
Fit the material delivery connection after driving is complete.
