As bulk material handling machinery designs become more powerful and increasingly efficient, braking system designs must also progress to satisfy the demand to control speed and stop machines in routine and, most importantly, during emergency stopping events.
Brakes are no longer straightforward on or off mechanical devices. Sophisticated Smart Brake deceleration controls with system status monitoring, fault acknowledgement, and feedback are required to maintain system integrity under all stopping conditions. This is particularly crucial on belt conveyor systems, where tension management and personnel safety are of paramount importance.
With these considerations in mind, Hilliard has developed a line of power units capable of controlling braking systems for a multitude of scenarios and applications.
APPLICATIONS
BBH2: Railcar Positioners, Wind Turbines, Cable Winders, Escalators, Overland/Underground Conveyors
BBH3: Overland/Underground Conveyors, Conveyor Tension Winches, Marine Towing Winches
BBH4: Grinding Mills such as AG, SAG, and Ball Mills
MK Electrically Released Caliper Brakes
Powerful floating caliper design can be used on conventional disc or rail applications. The compact spring-applied design provides easy installation and maintenance. Spring force and air gap can be adjusted to match torque requirements.
The patented Hilliard MK Guide Rail Brake is designed for use on elevators, conveyors, cranes, or other devices requiring a spring-applied electromagnetically released brake. The patented MK brake can be applied to a guide rail or a brake disc.
Magna Torque (MT) for Backstopping & Indexing
Hilliard’s line of overrunning clutches is economically priced and ideally suited for backstopping and gearbox applications. Custom designs and rapid prototyping are available.
Magna Torque (MTR) for Clutch Couplings,
Dual-Drive & Turning Gear Roller-Ramp design for increased reliability and longer life.
An integral part of many Hilliard motion control products is our roller-ramp design. The use of hardened cams and precision-machined rollers maximizes service life.
There is almost no wear during freewheeling operations because rollers are free to rotate between the outer member and the inner cam. When the rollers are engaged, the load falls at random positions on the rollers. The result is superior service life and
reliability.The MTR is similar to the MT design except the cam surface is reversed allowing it to be used in multi-speed/dual drive applications.
Overrunning Clutches
Hilliard’s enclosed overrunning clutch incorporates superior MTR design in a totally enclosed package. Designed for power transmission operations, this clutch is totally contained in a stationary housing for constant protection from hostile environments or wash-downs.
Hilco Oil Reclaimers Comprehensive Contamination Control for Hydraulic Systems
If your application involves oil with substantial amounts of water or volatile contaminants, an oil reclaimer may be the most cost- effective solution to your contamination problem. The addition of settling and clean-oil holding tanks, filters and controls converts the basic Hilco Oil Reclaimer into an extremely efficient reclamation system. The reclamation process uses a combination of filtration and vacuum distillation to purify the oil and return it to a like- new condition. Other contaminants best removed by this process include acids, solvents, dissolved gases — almost any volatile contaminant. Although most reclaimers are part of a permanently installed system, they can be made portable for the greatest flexibility in dealing with your application.
Supplemental Protection for Other Locations
A particular set of operating conditions may require contamination control in addition to that provided by the off-line loop. Examples include pressure-line filters for in-line protection of remotely mounted critical components, and reservoir air-breather filters to protect against ingestion of airborne contaminants in hostile atmospheres. Hilco products are available for these special applications, and Hilliard's applications specialists can advise and assist you in the selection of such equipment for supplementary locations.
