26fold special gear
Use: cylinder head connection on diesel engine at Caterpillar
Speciality: 26 screws conneting on the same time
The Stichmaße of the screws and the high torque moments are responsible that standard nut runners with offsets gears could not be used. Only the summary of all
The pitches of the nut runner and the high torque moments made it impossible to use standard nut runners. Only the addition of all drives made it possible to have the small distances between the outputs.
The drive box is made out of high-strength aluminium, all pinion gears are bedded twice, square adapters for drive screws, multi key output shafts
Size: 1000 mm x 400 mm x 100 mm / Gear reduction 1:3,5
Input torque moment: max. 210 Nm
Output torque moment: max. 630 Nm
Efficiency > 0,93, Repeat accuracy < 2%, Lonlasting one-time grease |

Inner Swing bearing
Use: Nut running of digger swing bearings at Hitachi
Support at component for tighening and loosing
Speciality: The high torque moments and the narrow disturb contour made is necessary to develop a spezial gear.
The head radius needed to be 30 mm max. and the overall hight needed to be less than 110 mm. The drive adapter can be connetect to the gear from both sides.
Nut runner with hanging and special gear, adjustable struts at gearbox for taking torque moments at component.
Maximum torque moment: 1.650 Nm |

Special gear for rotating assembly 1650 Nm
Use: Nut running of digger rotating assemlies at Hitachi
Speciality: The high torque moments and the narrow disturb contour made is necessary to develop a spezial gear.
The head radius needed to be 30 mm max. and the overall hight needed to be less than 110 mm. The drive adapter can be connetect to the gear from both sides.
The gear box is made out of high-strength aluminium, double cog wheel for transfering high torque moments on “smaller” drive pinion, all pinions double embedded. Square adapter for drive screws, evolvent output shaft
Size: 300 mm x 200 mm x 110 mm
Gear reduction 1:2,3
Input torque moment max. 210 Nm
Output torque moment max. 630 Nm
Efficiency > 0,91, Repeat accuracy < 2%, Lonlasting one-time grease |

Outer Swing bearing
Use: Nut running of digger rotating assemblies at Hitachi
Strut on component for tightening and loosing, mobile system with integrated controller
Speciality: The high torque moments and the narrow disturb contour made is necessary to develop a spezial gear.
The head radius needed to be 30 mm max. and the overall hight needed to be less than 110 mm. The drive adapter can be connetect to the gear from both sides.
Nut runner with carriage and spezial gear, adjustable struts at gear box for taking of torque moments at component, lining of nut running unit via pneumatical cylinder,
Maximum torque moment: 1.650 Nm |

Pedal unit pre-mounting site
Use: Pre-mounting of pedal units at VW
Adjustable bear on system for different components
Speciality: the high variety of mounted components needed a high flexibility for bearing on possibilities of components,
Base frame out of aluminium, adjustable bear on points for different components, rails on top of pre-mounting site for attachment of a nut runner, controller unit mounted on view height, small-SPS for release of mounted components based on o.k.-counting in box with air and electrical connection |

Arrester for bolt-nut-connection
Use: nut running of balancer leverages at DaimlerChrysler, Self-tracking nut
arrester Speciality: The high variety of components didn’t allow the strut of torque moments at the part. So a system for nut arresting has been developed, where the torque moments are supported over the nut, that is arrested after a short time. The arrester nut can be changed with one turning.
Aluminium clamp unit for connection at nut runner, guide pillar in ball lining for transfer of torque moments, throttle cable clip for tracking during nut running
Maximum torque moment: 320 Nm |
|
|
Underroller
Use: Nut running of underrollers at Hitachi
4-fold nut runner with electrical pitch adjustment
Speciality: Differend underrollers needed adjustable pitches. The underroller type is identified via barcode wich adjusts the needed pitch automatically.
Aluminium clamp unit for connection at nut runner, guide pillar in ball lining for transfer of torque moments, throttle cable clip for tracking during nut running |

Couterweight Nut Runner
Use: Nut running of digger counterweights at Hitachi
Strut on neighbouring bolts, adjustable for different distances, mobile system with integrated controller
Speciality: To absorb the high torque moments via a safe strut and to lead the into mechanics. Elastic key head for safe adaption of counterweight.
Nut runner with carriage, adjustable strut on swivel arm for taking reaction moment on neighboured screw heads, lining of nut running unit via pneumatical cylinder,
Maximum torque moments: 4.000 Nm |
