Hi-Lo Retrokit Davenport

Roll Clutch Removal Increases Productivity

Mechanical Roll or “Rollaway” clutches have a tendency to slip and grab at different points during speed changes and indexes - causing expensive tool breakage and downtime when the machine goes past low-point in high

-speed. Since Logan clutches improve cycle time repeatability, our low-speed clutch replaces the old-style roll clutch and enables set-up personnel to position tools closer to the work-piece, further reducing dwell time and overall cycle time.

Roll Clutch Removal

• Cycle time repeatability within tenths of a second over millions of parts.
• Reduces possibility of going past low-point and crashing tools during the high-speed cycle.
• Eliminates maintenance and downtime related to roll clutch adjustment.
• Field retrofits with existing Logan Retrokits.

View of a typical Davenport timing chart. As you know, Davenports rotate counter clockwise. The Logan Hi-Lo Retrokit enables your Davenport to enter into high speed a few degrees earlier (55 degrees vs. 60 degrees) and stay in high longer (95 degrees vs. 92.5 degrees), thereby allowing your machine to “get back into cut” much faster. It takes less time to get back into the cut, over a period of millions of parts – which increases your machines overall productivity using the same operator, machine and floor space.

Overall, these basic speed changes enable your Davenport to improve cycle time by 10%, and sometimes more depending upon the job.

Here are some other areas of savings based on user reports:

1. Speed and consistency of index. 

2. Can be adjusted to any shift point (on-off) to optimize work cycle time. 

3. No end thrust on starting and high-speed shafts, drastically decreasing the need for maintenance. 

1. Taper cone bearing
2. Thrust washers
3. No rolls and pins
4. No shifting shoes and pins
5. No high speed cam to wear out
6. No high speed lever to adjust
7. No chucking mechaniziums to grease
8. No levers and pins to break
9. No engaging sleeves to wear out
10. Will not pop out of gear
11. No rolls to wear out in roll clutch 

4. Snuber brake mounted on high speed shaft eliminates the need for a mechanical one 

1. No need for adjustments
2. Does not pull down on 5080-20-10 shaft
3. Will not wear out $500.00 bronze worm gear
4. Will not wear out cam carrier bushings
5. Can be applied as needed throughout the work cycle for drastic drop off cams
6. Is only applied when needed saving on electricity cost, decreasing load on electrical components.

Hi-Lo Retrokit Leads to New Control Capabilities

Now that your machine is equipped with a Logan Hi-Lo Retrokit, integration of simple, efficient controls is a breeze. That’s why we now include our CS2001XT16 as standard equipment on all factory supplied Logan Model B Hi-Lo’s. The XT16 displays cycle time, machine position in degrees or hundredths, and enables you to electronically program attachments and devices normally operated by cams and limit switches. This leaves you room to easily expand into more productivity enhancements such as broken-tool, short- part detectors, bar loaders and feeders. Call Logan for more details.

1. Achieve maximum torque with our High-Capacity^TM starting clutch.
2. Self-adjusting disc pack guarantees cycle time repeatability. Eliminates the need for mechanical adjustment.
3. Quick-stop, power-applied brake. Ideal for bar loader applications.
