How BreakAlube works Security build-in: Diagnosis
How BreakAlube works Experiences with hydraulic hammers shos that 60 seconds is needed in order to offer the maximum dose of grease. That is why BreakAlube will automaticly start a greasing cycle, after the hydraulic hammer has been operating for 60 seconds, in which the preset amount of grease is discharged at the hydraulic hammer greasing point. The grease quantity, 0.2 cc minimum to 4.0 cc maximum per greasing cycle, can be set in the Digital Control Unit. The quantity will be both highly accurate and constant, regardless of the grease temperature or viscosity. This is achieved by measuring the number of pump element strokes. A warning light in the cab will alert the operator when grease is low, the reservoir empty, or when a system error occurs. BreakAlube also allows automatic hammer deactivation as soon as proper greasing is no longer warranted (activation upon request). Security build-in: To prevent damages to the hydraulic hammer or BreakAlube, the system features important standard built-in safety provisions. • BreakAlube will only grease when the hydraulic hammer is in operation. Greasing an inoperative hammer may cause damage in certain situations when the hammer is activated. • BreakAlube cannot build up sufficient pressure in the discharge line when the grease reservoir is empty or when an external line is damaged. In that case, a pressure switch will automatically switch off the pump. • If the pressure in the grease pump runs too high, e.g. because the hydraulic hammer is not connected, a built-in safety valve will ensure that the grease is pumped back into the reservoir Eventually, the pump will also switch off automatically. • Whenever an error or failure occurs, a warning light will alert the operator. • Optionally, switches off the hammer should proper greasing not be guaranteed. Diagnosis The Digital Control Unit features a memory to store parameter settings and operational data. The greasing settings can be changed with a GINA handheld computer, which also allows you to read out the memory for diagnostic purposes. Pressing the BreakAlube test button for several seconds allows the operator to check the cause of any current error during work. The cause of the error is shown by the flashing warning light in the cab. •Heavy-duty tempered pump element for long life •Heavy-duty eccentric drive axle bearings • Under-pressure and overpressure detection with warning signal • Grease reservoir with springoperated follower plate • Low grease and empty reservoir warning • Automatic hydraulic hammer switch-off, to be activated upon request Digital Control Unit Higher operational safety BreakAlube features a Digital Control Unit that ensures technically correct and safe completion of the greasing cycle. No standstill and repairs due to insufficient or irregular greasing. Less greasing costs •T he timer function will start the greasing cycle after every 60 seconds of operation of the hydraulic hammer. • Monitors the discharged quantities of grease and the working pressure in the system. • Monitors the integrated overpressure valve. • Alerts the operator to system errors and low grease. (blinking light). When the grease reservoir is completely empty, the light will be on continuously. • Optionally, switches off the hammer should proper greasing not be guaranteed. • Diagnosis function Less wear Grease reduces wear of moving parts and effectively combats moist, dirt and corrosion. T e chn i cal s p e c i f i cat i ons Grease types: up to NLGI Class 2 Grease output per cycle: 0.2 - 4.0 cc Maximum working pressure: 275 bar Operating voltage: 24 Vdc Current draw: 2A Grease reservoir: 3 litres www.groeneveld-group.com Thanks to greasing during operation and accurate (temperature-independent) grease dosage, the grease consumption will on average increase by 50 percent. Additionally, the grease can be purchased in larger amounts (drums instead of cartridges) and is therefore cheaper. Less environmental impact Lower grease consumption means fewer pollutants in the environment. The closed construction and the reservoir with a follower plate make the Twin particularly suitable for biologically degradable grease types. Preservation of wrecking hammers BreakAlube When the going gets tough BreakAlube is specifically designed as an automatic greasing system for hydraulic hammers. BreakAlube offers excellent operational reliability under the toughest working conditions. The vital pump parts, including pump element and drive axle bearings, are extremely strong and can build up working pressures up to no less than 275 bar. BreakAlube can be used with greases up to NLGI Class 2 including additives such as graphite and copper. Groeneveld Durability from within!
