FLO’s installed Lincoln Quicklub Automated Lubrication System consists of a 12/24 VDC Series 203 pump with a 5 lb reservoir, SSV positive displacement, grease metering valves, fittings, tubing and hose. The pump moves lubricant to the many lubrication points via progressive metering valves custom-sized for each series of points. The valves incorporate a series of metering pistons, which provide precise lubrication from each outlet. Our automated greasing systems typically service your king pins, tie rods, steering drag link, slacks, shackle pins, spring pins, transmission cross shaft, brake shafts and fifth wheel if applicable. Optional monitoring will provide a warning light in your cab indicating reservoir low level and non-delivery of lubricant to your bearings.

FLO’s Automatic Greasing Systems are also routinely used on special purpose trucks, such as garbage, concrete, fire, buses, snow plows, street sweepers and vacuum. Grease points on these vehicles are often difficult to access and are subjected to dirty, wet environments. Adding further complexity, some have over 50 grease points. Your installed autogreasing system lubricates during frequent turns, stops and starts, and promotes up-time and reliable performance as you work to meet tight deadlines.

FLO’s installed SKF MonoFlex Fluid Grease Automatic Greaser is a single-line grease system, consisting of a gear pump and reservoir available in 2.7 Litre (6 lb.) and 6 Litre (13 lb.) sizes, external control unit and parallel type piston distributors. The timer-controlled pump supplies fluid grease to the distributor blocks via the main line when the pump is in operation. When the metering chambers of the distributors are full, the excess grease flows back into the reservoir via a safety valve. At the end of the pump run-time (start of the interval-time), the pressure relief valve opens and drops the main line residual pressure to 3 to 15 psi. The spring-loaded pistons in the distributors then discharge independently of each other, precisely measured amounts of grease from the metering chambers to the grease points. On a transport truck, our Automatic Greasing System typically services your king pins, tie rods, steering drag link, slacks, spring pins, transmission cross shaft, brake shafts and fifth wheel if applicable.

Completely reliable and fully automatic, a FLO Autogreaser will increase your component life and overall productivity. The Auto Greasing system dispenses small measured amounts of grease at frequent intervals while your equipment is operating, maintaining a consistent grease seal to prevent dirt and contaminants from migrating into bearings. It will help keep your rolling equipment out on the road making money and reduce your labor costs when compared to the traditional method of point-by-point manual greasing.

Automatic Greasing Systems for Commercial, Municipal & Construction Trucks Municipalities, fleet operations and transportation companies are constantly under pressure to save money, increase productivity and make every investment in commercial vehicles last longer. FLO’s Automatic Greasing System is ideal for all of your heavy duty truck applications – liquid or bulk dry, shunt trucks, city delivery, regional or long haul. Large fleets can expect to save hundreds of thousands of dollars over the life of their equipment, by lowering costs and improving efficiencies.

Automatic Greasing Systems for Trailers A quad axle trailer has between 30-40 grease points. Greasing on a weekly basis takes between 2 – 3 hours based on shuttling the trailer to and from the lube bay combined with finding, reaching, cleaning the fitting and then actually greasing the point. This equals $2000 per unit per year in direct labor costs, plus the lost revenue time. If a grease point fails due to lack of grease, associated downtime can easily exceed labour costs. On a typical Quad axle trailer, a FLO Automatic Greasing System will service axle pivots, axle locks, slack adjusters and brake shaft tube.

Bearing failure resulting from improper greasing is a major cause of equipment downtime and significant unnecessary maintenance costs in today’s environment. The majority of failures are caused by: contamination of bushings by dust, dirt and moisture; inadequate amounts of grease applied to bearings; or over-greasing of key pivot points.

Direct costs resulting from inadequate greasing can include: replacement bearings; labor to repair or replace bearings; lost time and its impact on customer service; or lost “on-road” time and replacement truck rental costs. Indirect, but very real costs of inadequate greasing include: wasted grease, environmental issues, safety or housekeeping issues, and higher labour costs related to inefficient manual greasing practices.

Abstract: Applying fin stabilizers is an effective solution for ship rolls on waves in a seaway. They generally consist of one or two pairs of retractable fins that are symmetrically mounted to both sides of the ship, effectively reducing the roll motion at low or moderate speeds. Fin stabilizers are commonly used by cruise ships for the comfort and safety of passengers. However, there is still little experimental and numerical analysis of the fins’ effect on hydrodynamic performance. In this study, the resistance performance of a cruise ship was investigated with/without fin stabilizers at different fin angles and ship velocities by model tests and numerical analysis. The CFD analysis provides a flow-detailed interpretation of the physical phenomenon, especially at an asymmetric maximum fin angle. The significant fin-induced resistance is newly discovered and averages up to 19% in calm water conditions, while the added resistance in waves is evaluated with a smaller increment up to 1.31%. By comparing the numerical and experimental results, this study provides insight into the resistance induced by overhanging fins, which provides an accurate prediction reference for cruise ship performance and benefits the fin stabilizers’ design and selection.
