EZ-Roll Form Movement System

EZ-Roll is a new, hydraulically operated roll back system for positioning side forms on long-line beds. Side forms are installed on a track and roller system. The rollers are designed to be tip resistant providing a safe and stable working area when the bed is open. Once the bed is set-up for casting, the side forms can be easily and quickly retracted with a hydraulic power unit.

Wheel carriages install under a bed’s soffit system and can easily be installed with a new bed or can be retrofitted on existing beds.

The EZ-Roll system moves an entire side of side forms at once and opens completely in seconds – not minutes, saving time, labor and crane usage. The advantages of time and labor are significant, but not as significant as the safety advantages. The use of heavy equipment like cranes in a precast plant can be dangerous and expensive. The new EZ-Roll powered side form roll back system is the easy and safe solution for side form movement.

Benefits Include:

  • Eliminates employee exposure to the hazards involved with the lifting and moving of side forms.
  • Decreases production cycle times allowing increased output and increased profits. Side forms can be opened up to 5’ in less than 20 seconds.
  • Reduces labor by as much as 90% on side form positioning when setting-up and stripping product.
  • Eliminates the use and expense of cranes and lifts for positioning side forms.
  • Provides a safe, stable, tip-resistant base for side form lines.
  • Extends the life of your girder side forms by eliminating form damage due to crane movement and storage.

Saf-T-Mate™ Catwalk System

Saf-T-Mate™ is a hinged, elevated, work platform and safety railing used to reach the top of tall side forms. It comes in ten-foot sections that attach to the side form with a simple hinged connection. Each section has three support arms and a grip strut walking surface to provide a safe, solid work platform. The safety rail attaches to the platform with a three-point post to connect and lock the rail in place. The safety rail is designed to withstand 200 pounds of force in any direction as required by OSHA.

Saf-T-Mate™ can be easily retrofitted on existing sideforms. Standard ten foot sections can be installed along the entire length of the sideforms by hand, with no special handling equipment, making it easy to use the platform and rail on multiple forms within the plant.

The hinged connection allows the platform and rail to drop out of the way when not in use and to provide clearance for curing covers. When dropped, the rail can be removed to allow the sideforms to be lifted or moved back for stripping.

Saf-T-Mate™ is a convenient alternative to a typical catwalk permanently attached to a form. It’s safer and more convenient than moving a separate structure in and out of place to reach the top of a sideform. Although most companies consider safety their highest priority; most companies struggle with finding a well-designed, safe and cost-effective catwalk system.

Saf-T-Mate™ is the answer.

Square Spiral Machines

The Square Spiral Forming Machine forms 6″ to 30″ continuous square spirals from wire up to 3/8″ diameter. The machine is powered by a 10 hp electric motor coupled to a variable displacement hydraulic pump. The pump displacement is variable for precise speed control without buildup of heat. The forming head jog and reverse functions are incorporated into push button controls. The forming head speed is continuously variable from 10 to 45 rpm. The predetermining electronic counter can be preset for a given number of turns per coil. The forming machine stops automatically after the preset number of turns is formed to eliminate manually counting back each time a coil is cut off. The counter keeps track of the batch count as well. The forming head stops automatically when the guard is raised. The different sized heads can be accommodated by moving the follower head carriage assembly toward or away from the forming head. The forming heads are mounted with split taper bushings for easy changeout.

Setup time is minimal due to quick release cam levers incorporated into the adjustments throughout the machine. An external air supply capable of 120 psi at very low volume is required to charge the air cylinder which acts as a spring on the follower head carriage.

COPANO BAY BRIDGE

Valley Prestress Products was recently awarded a contract for the prestress products for the Copano Bay Bridge in Rockport, Texas. The project includes four hundred and sixty 54-inch cylindrical piles with a 42-inch voided center, ranging in lengths from 83 to 168 feet.

The round piles were a new product for Valley Prestress. A new bed, forms and an efficient production process needed to be developed to produce the new product.

Valley Prestress installed a 520-foot bed, staging and curing areas to produce the piles. Hamilton Form fabricated the cylindrical pile forms with a hydraulically actuated interior void and two piece headers. The two part outer form was designed with integral hold ups and hold downs to keep the void in place during the pour. Production is running smooth.

UNISTRESS WAFFLE SLAB FORM

When Unistress Corporation of Pittsfield, MA needed formwork for some unusual floor slabs, they called on Hamilton Form. Each slab has a series of holes for ventilation pipes and wire chases. The slabs form the floor of the clean room for a stateof-the-art semiconductor foundry being built in upstate New York. The 22’ long by 8’ wide slabs have an overall perimeter depth of 4’ and weigh as much as 24 tons each.

The formwork had to be extremely efficient for set-up and stripping, while maintaining strict tolerances. Steel alignment plates are used to precisely place the voids that form the cylindrical holes. To simplify stripping, the upper disc assembly is positively pulled out of the product and void by turning its mounting bolt. Sideforms pivot back for stripping.

The self-contained precast forms allowed for ease of set-up. A few innovative features simplified what could have been a complex set-up and stripping process. The “fabricator friendly” formwork performed perfectly, to help keep the project on time and within budget.

SELF-STRESSING JUMBO TEE

Precast, prestressed concrete is a highly engineered, complex product that requires a precision-fabricated, high-quality, durable formwork.

That’s why, when The Shockey Precast Group needed to cast a unique double tee product, they called on Hamilton Form Company.

The “Jumbo Tee” has sixty inch stems with a highly stressed bulb configuration at the stem bottoms. Hamilton Form built the self-stressing formwork in sections for both shipping and stripping considerations. The stems have minimal draft requiring the sideforms to be pull back for stripping. The 118-foot long, twelve foot wide product is casting efficiently and strips easily, keeping productivity high and delivery on time.

INDIAN STREET BRIDGE

The new Indian Street Bridge will cross the south fork of the St. Lucie River to connect Palm City with the city of Stuart in southeastern Florida. The bridge has a haunch girder center section and the newly introduced FIB78 (Florida I-Beams) on the approach spans.

CDS Manufacturing in Florida recently added several new beam lines to produce the new Florida beams including a dedicated line to produce the high volume FIB78 for the Indian River project. This project however, also calls for haunch girders.

Hamilton Form quickly went to work to design and build formwork to cast the haunch girders. The girders are 114-feet long, 11-feet tall at the center, and slope to 6-foot, 6-inches at the ends. A recess in the sideform creates the haunch at the centerline. Forms were completed with a hinged catwalk, railing, and Vibrotrack.TM

Hamilton Form also supplied CDS with galvanized embed and beveled plates for the project.

TAPERED LIGHT POLES IN HAITI

Concrete light poles are more durable and have a longer life span than typical wood poles, two important features – especially on a tropical island. For that reason, concrete poles are being specified more often, especially in coastal areas. A precaster who was setting up a plant to produce concrete light poles in Haiti reached out to Hamilton Form for formwork.

The first set of forms were ready to ship just as Hurricane Irma made her way into the Caribbean. With winds of 185 mph, Irma caused devastation in the eastern Caribbean, swept across Puerto Rico and then hit Florida. Irma caused over $64.8 billion in damage. As residents began assessing the damage from Irma, Hurricane Maria followed right behind. Maria made a direct hit on the Island of Hispaniola, desolating the nations of Haiti and the Dominican Republic. Maria, one of the costliest hurricanes in history, caused $94 billion in damage.

Over the last decade, weather events including tornados, floods, wildfires and hurricanes have become more intense. This new reality of superstorms calls for more durable, resilient building materials such as precast concrete. We expect the market for precast products used for infrastructure projects will continue to grow. The forms made for light pole production will help deliver more reliable lighting to the people of Haiti. Hamilton Form is proud to have contributed in a small way to make that happen.

The pictured form was built to produce prestressed tapered light poles at varying lengths, from 45 feet long to 30 feet long in 5-foot increments. A set of headers was provided for each length. Headers and jacking plates for the forms were lettered or numbered to assure each set stays together. The dual-cavity forms were built in 100-foot lengths and were designed to cast four products at a time, tip to tip. The forms are self-stressing to produce durable and resilient light poles.

Median Barriers

Median Barrier forms may vary greatly in height, width, and geometry depending on state requirements. Other design factors are permanent or temporary placement, tapered or transitional designs, and highway or surface street applications. Forms are generally designed to cast the product upside down in drafted forms.

Optional Features Include:

  • Single line and dual line forms.
  • Drainage Blockouts on top of the form.
  • Stake Pocket Blockouts in many configurations.
