The Ultrapac® is a four-at-a-time concrete products machine that produces up to 2160 units (eight inch equivalents) per hour. Consistent and precise concrete masonry units are produced on this machine, at speeds up to nine cycles per minute. The Ultrapac was designed to be one of the most flexible concrete products machines available. 


Cam Driven

The Ultrapac is cam driven to deliver consistency and repeatability of movements. The precise indexing of the cams achieves uniform product quality even in variable operating conditions. 

Frequency Drive

A variable speed frequency drive replaces the standard variable speed pulley drive. The variable speed frequency drive is remotely controlled from the SLC 5/05 control panel, compared to manually adjusting the variable speed pulley. 

Automatic Lubrication

Precisely measured amounts of lubricant are automatically supplied to key bearings and pins. This routine maintenance function insures optimum performance of the Ultrapac. 

Allen-Bradley Control Panel

Many of the operating functions of the Ultrapac can be easily adjusted by accessing the SLC 5/05TM through the color graphics display unit. This control panel automatically pinpoints problems and displays information for making corrections fast, and stores machine settings which are retrievable by entering product codes.

Automated Cutoff Bar

An automated cutoff bar controls the product height and density. A motor driven cam raises and lowers the cutoff bar. This new design eliminates the need to disconnect autofeed linkages for height changes and allows the feedbox to always remain level. 

Rotary Position Sensor

The sensor provides cam position information to the controller. This allows adjustments to be made to the machine set points while the concrete products machine is operating. Adjustments are made through the color graphics display unit. 

Bescodyne Vibration

Standard Bescodyne vibration provides rapid engagement of vibrators to provide quick and smooth starts and stops, optimum compaction and consistent, uniform concrete products. 

Bescodyne Hydraulic Clutch/Brake

The Bescodyne hydraulic clutch/brake on the main drive and vibrators provides quick and smooth starts and stops. 

Optional Enhancements

AFC Smartpac® Vibration

By employing independent amplitude and frequency control, vibration is tunable to specific molds and product requirements. The ability to control both amplitude and frequency results in more rapid compaction and quicker finish times than can be obtained with conventional vibrating systems. Vibration can be engaged or disengaged multiple times within a single machine cycle. 

Posapac® Dual Vibration

Dual vibration utilizes a Bescodyne clutch/brake which allows the concrete products machine to use Posapac weights for short production orders. This is beneficial if several existing molds are owned with weights attached. AFC SmartPac can then be used for longer production orders or for manufacturing specialized products. 

Head Vibration

Provides an additional .04" - .12" (1 mm - 3 mm) of compaction resulting from the vibration of the head. This option is only available for the 26" (660 mm) deep Ultrapac and is used for product heights up to 80 mm (non-cored units). 

Air Compaction

The use of air compaction reduces finish time, which improves overall cycle time. Air cylinders supplement the force on the mold exerted by the weight of the machine head. The addition of compressed air restrains the stripper head bringing the height pins together sooner, compacting the unit faster and more effectively. 

Pallet Receiver Cam Inserts

Pallet receiver cam inserts allow for rapid height changeovers for certain mold configurations between 2" and 7-5/8" (50 mm - 190 mm). 60mm, 3-5/8", 5-5/8" and 7-5/8" flat top molds can be run from the 7-5/8" position and do not require moving the inner frame. Other product heights may be able to run from this position depending upon the mold configuration. 

Frequency Drive for Main Drive Speed Control

The frequency drive controls the main drive speed control so that specific segments of the machine cycle can be slowed down or sped up. This feature slows down the stripping speed without sacrificing overall cycle speed. The variable speed frequency drive is remotely controlled from the color graphics display unit. 

Vibrator Motor Air Bag Lifts

The vibrator motor air bag lift is an easy and quick way to raise the vibrator motors for mold changes. A lever operated pneumatic valve is moved to the up position allowing air to flow into the air bags. When the bags inflate both vibrator motors rise. This allows the operator to remove the belts and begin the mold change procedure. A safety lockout device is included for safety during maintenance. 

Core Puller

A core puller is an attachment for the concrete products machine. It is comprised of a drawer which is activated by either hydraulic or pneumatic cylinders to which the “forks” required to form the horizontal cores are attached. The core puller is installed in front of the mold on the concrete products machine, above the front delivery conveyor. It can be wheel-mounted or leg mounted.

Mold Insertion Device

The time needed to change molds is shortened and simplified with the mold insertion device. This pneumatic powered mechanism lifts/lowers the entire mold assembly off/onto the mold throat. The entire mold assembly is manually rolled into/out of the mold throat area. 

Pallet Scraper

Material build-up on pallets is automatically removed during each machine cycle. The tension forcing the scraper blade down on the pallet is fully adjustable to meet specific cleaning needs. 

Automated Head Clamp

Hydraulic clamps with wedge locks are used to clamp and hold the stripper head in the concrete products machine during production.
