Logan XT16 Chip BreakerTM Software

By Michael Krizmanich
December 27, 2016 Category • General, Screw Machine

Logan Clutch now offers Chip Breaker technology on its line of CS2001 XT16 Microprocessor Controls. Chip Breaker technology enables Acme, New Britain, Davenport and Wickman users to minimize or eliminate nesting of metal stringers that occur in the feed cycle (when making aluminum parts). This feature minimizes the need for operators to tend to or shut down the machine to clear chips. In addition to the Chip Breaker software settings, other factors must be considered and potentially modified. These are the feed rate and the tooling. Industry feedback is that it should take no more than 2-3 revolutions of the spindle to break the chip, whether you are using a chip breaker cam or our software. The feed rate must also be considered and keep in mind the back pressure of the feed, which varies during the cycle. Note that a hard coded timer is used in the logic that ensures the machine does not dwell for more than 1/2 second. This is done to avoid a machine lockup condition by using these

Logan CS2001TM Controls Support Door Interlock / Start Interrupt Switches

OSHA rulings and regulations are requiring screw machine users to upgrade their machines with door interlock switches. The purpose is to ensure that the machine cannot be started when a door is open, and the main motor stops when a door is opened. The CS2001 control from Logan Clutch is a solution that has passed OSHA scrutiny in hundreds of machines. It works with the dedicated inputs of the CS2001 control and the three levels of programming security in the software. One security level is Set-up mode. Access to Set-up mode is controlled and secure. When a machine door is open it can only be jogged while in Set-up mode only. This enables CS2001 users to work in the tool zone, jog the machine and know that the machine cannot be started. CS2001TM Door Interlock / Start Interrupt Switch Inputs: How They Work The CS2001 Microprocessor Control has two pairs of inputs for two Door Interlock Switches. Each pair of is designed for one normally opened switch contact and one normally closed switch

October 12, 2016 Category • General, Mobile

OEM Manufacturer of Construction Equipment Works Together with Logan Application Team The Challenge: Before OEM contacts Logan to solve system issues which are causing hydraulic pump failure Most OEM manufacturers of mobile equipment use hydraulic piston pumps to control machine movements and attachments. In many cases these hydraulic piston pumps are driven remotely from the engines auxiliary PTO drive via a slip yoke shaft. Machine Operators must be able to turn these pumps on and off when the vehicle is driven from job site to job site - in order to prevent over speeding the pump when the engine is running faster than the pumps normal hydraulic work speed. There is also the potential for all the pumps to engage at once, which would cause the input torque rating to be above the engine specifications causing hydraulic system and pump failure. In this situation, customers were going beyond the limits of the machine and pump specs the OEM had to do something quickly -they contacted

Power Take-Off (PTO) Clutches - Oil and Gas Applications

By Ed Gallucci
October 11, 2016 Category • Oil Gas, Power Take Off (PTO) Clutches Oil And Gas Applications

In this Oil Gas vehicle application, the Logan SAE 600 series Direct Drive PTO is mounted on a typical 2-pad live PTO pump pad, sandwiched between a CAT 3412 Diesel Engine and an Allison 8900 Series Transmission. The Logan 600 series Direct Drive Power Take-off (PTO) clutch will connect or disconnect the single and tandem pumps mounted to the live PTO pump pad. The pumps are used only on the job site, and remain disconnected(via the Logan PTO) when the vehicle is idle and not in use, or when driving to and from the job site. This option to clutch-in and clutch out the pumps minimizes wear and tear on the pumps, reduces unnecessary fuel consumption, and the chances of over speeding the pumps (since they are disconnected from the drivetrain) when the vehicle is at highway speeds during transport.

A pipe lay barge is a specialized vessel which may require up to eight (8) winches to operate simultaneously to properly lay pipe on the ocean floor. This particular barge company winches were equipped with conventional winches that used dog-type clutches used to manually engage and disengage the winch. This was a difficult and laborious procedure since it was nearly impossible to get each winch properly aligned before engagement. With the Logan hydraulically operated, self-adjusting CH series clutch, engagement and disengagement of the clutch is done remotely with the press of a button, from the comfort of the wheel house control room - with the option of local push-button engagement as needed for testing. The barge operator now benefits from faster operating start-up operations and requires less man power to run the winch operation on his vessel. The particular Pipe Lay Barge is equipped with 8 Mooring Winches and 2 Anchor Winches (130 ton Winches). Each Winch, including the anchor

When Canadian towing and barge services provider Island Tug and Barge encountered problems with the mechanical clutch system on one of its tugs, it turned to Logan Clutch to provide a solution. Island Tug, based in Vancouver, British Columbia, offers towing and barge services, including ramp-equipped deck barges, aggregates and general cargo, as well as cable installations. The companys towing services extend to the Pacific Rim, and it also has facilities on Canadas eastern seaboard. Island Tug had been running two generator sets on the tug Island Scout. These ran pumps for the main hydraulics and bow thrusters off the back of the engines. In order to do this, both engines were equipped with conventional, mechanical lever actuated PTO clutches to drive the pumps. The problem was that these clutches started to fail during full rev/min engagement. Generator sets normally run at 1,800 rev/min and cannot be slowed down to allow for clutch engagement. These failures were creating frequent
