Product Handling

Concrete pipes, manhole & box culverts are heavy, unwieldy items, difficult to move and easy to damage, especially in their uncured state. HawkeyePedershaab takes this physical and emotional stress out of the production equation through their full range of automated product handling solutions.

Whether the need is carefully transporting freshly-produced 300mm (12”) pipe from the pipe machine to the curing area, where the slightest accelerations can damage the product, or the need is taking a cured 3000mm (120”) concrete pipe, removing its massive pallet and header and transporting it out of the building, untouched by human hands, HawkeyePedershaab has expertise and experience in handling the task.

Product handling, in its very essence, is quite simple. Take a freshly produced concrete product, move it into a curing area. Take that same concrete product hours later, after it has sufficiently cured, remove its joint rings and move the product to the stockyard. The concept is simple, the challenge is in the execution – and HawkeyePedershaab executes these tasks with excellence, day after day, in factories all over the world – and has done so for 30 years.

HawkeyePedershaab offers, and has provided, product handling solutions for nearly every conceivable concrete product – systems for the processing of round pipe, elliptical pipe, box culverts, manhole risers, cones, catch basins, bases & slabs – and combinations thereof.

Automatic Demoulding Cranes

Often, the pace-setter in a concrete pipe factory is the man either driving the pipe cart or operating the overhead stripping crane. A plant’s productivity and efficiency is in the hands of one man – a man who can become ill, take a vacation, quit his job, etc.

Whether the machine is a self-stripping machine like a Mastermatic or a KastMaster, or is a crane-stripping machine like a PipePro or a packerhead, HawkeyePedershaab can offer automatic and reliable solutions for moving the fresh concrete pipes from the machine to the curing area.

This is often the most critical piece of automation in the factory, ensuring the plant’s efficiency and productivity remains at the highest levels, day after day.

 

 

Features & Benefits:

  • Eliminates costly plant labor and ensures consistent machine cycle times
  • Increases plant safety by keeping human personnel at a distance from the operation
  • Soft, computer-controlled motions to prevent product damage
  • Adaptable to both moving floor and open floor plant layouts

Moving Floor Systems

The most advanced and effective way to cure your concrete products is to use a moving floor system. Such a system immediately brings your concrete products into a humidity and heat-controlled environment and advances them through a carefully-controlled curing process that in approximately 6-8 hours, result in a sufficiently cured product that it is able to be automatically handled with confidence.

Such moving floor systems consist of a series of large, flat pallets, on which the products are placed, that ride on floor-mounted rails and are carefully controlled by floor-mounted rubber drive wheels – advancing the concrete products through pre-cure, curing, and post-cure chambers and ultimately to an automatic unloading station where the cured products are removed from the flat pallet. It is then returned to the production machine for more products.

Features & Benefits:

  • Variable-frequency controlled rubber drive wheels allow for soft acceleration and deceleration of concrete products, preventing any product damage
  • RFID (radio-frequency identification) system for each flat pallet to ensure proper identification of products throughout entire cycle

Set Ring Removal

In automatic factories that are using temporary set rings rather than stay-in-place headers, HawkeyePedershaab provides robotic manipulators to remove the set ring from the pipe or manhole after the concrete has had its initial set and return it to the machine for re-use.

This is a critical safety element in the factory as it prevents human personnel from entering areas of operating automatic equipment. HawkeyePedershaab provides set ring retrieval solutions for both moving floor curing systems and open – floor, overhead crane-based curing solutions.

Features & Benefits:

  • Eliminates costly plant labor
  • Increases plant safety by keeping humans away from automatic equipment
  • Automatic adjustment to all set ring sizes
  • Adaptable to both moving floor and open floor plant layouts

Automatic Pipe Handling Cranes

In order to keep the production machine in an automatic factory running at its peak efficiency, it is important to eliminate any downstream bottlenecks. A common factory bottleneck is getting the cured products out of the curing system to make room for new, fresh products.

HawkeyePedershaab offers numerous solutions for this task for many different plant layouts, including both moving floor and open floor curing setups.

 

Features & Benefits:

  • Eliminates costly plant labor and ensures consistent machine cycle times
  • Increases plant safety by keeping human personnel at a distance from the operation
  • Automatic adjustment between all product sizes
  • Capable of handling round, box, arch and oval shaped products
  • Soft, computer-controlled motions to prevent product damage
  • Adaptable to both moving floor and open floor plant layouts

Pallet Removal

One of the most time-consuming processes in a concrete pipe or manhole factory is the removal of the pallet from the cured product. HawkeyePedershaab has designed numerous depalletizing solutions, each tailored to the specific task required.

The HawkeyePedershaab depalletizing solutions are uniquely effective in their use of a combination of horizontal, high-frequency pneumatic tapping and vertical hydraulic pulling, ensuring a quick and gentle removal of the pallet from the concrete product.

In fully-automatic systems, the pipe or manhole is introduced into the depalletizer using an automatic manipulator and in standalone or semi-integrated systems, the pipe is carried to the depalletizer using a fork truck or electric transport cart.

Features & Benefits:

  • Eliminates dangerous and time-consuming labor
  • Protects pallets from manual sledgehammer damage
  • Flat surface with clean-out pit below for easy clean up
  • Ability to pull from the outside or inside of the pallet
  • Easily replaceable pulling-bits
  • Capable of pulling round, square, oval or arch-shaped pallets
  • When loading with a fork truck, ability to handle out-of-center product
  • Automatic adjustment to all pallet sizes

Header Removal

Removing headers (top rings) from cured concrete pipe is a delicate, time-consuming process that, if done improperly, can result in a damaged or pulled spigot – necessitating the scrapping of the pipe. HawkeyePedershaab’s patented header removal system utilizes the principle of “D-Wedge” to carefully and consistently remove the header without damaging the spigot.

The HawkeyePedershaab header removal systems engage a machined groove in the header at either two or four points, and use a combination of pneumatic tapping and gentle hydraulic pulling to quickly remove the header.

In fully-automatic systems, the header removal device is built into the product manipulator and in stand-alone or semi-integrated systems, the pipe is carried to the header removal station using a fork truck or electric transport cart.

 

Features & Benefits:

  • Eliminates dangerous and time-consuming labor
  • Protect headers from sledgehammer or dropping damage
  • Patented “D-Wedge” removal system to protect spigots
  • Easily-replaceable pulling bits
  • Capable of pulling round, square, oval or arch-shaped headers
  • Occurs simultaneous to pallet removal for reduced cycle time impact
  • Automatic adjustment to all header sizes

Product Tippers

The final step in the product handling process involves taking the pipe or box culvert from the vertical to the horizontal position for fork truck yarding. This tilting-down process is very laborious and is a common source of factory injuries as well as product damage.

HawkeyePedershaab offers numerous tipping solutions, ranging from massive, stand-alone tippers used in the tip-down of large pipes and box culverts to more moderately-sized tippers that are integrated into fully-automatic handling systems.

Features & Benefits:

  • Eliminates dangerous and time-consuming labor
  • Protects concrete products from damage related to tip-down
  • Automatically adapts to all shapes and sizes of pipes and box culverts

Pipe Sorting Systems

One of the benefits and hallmarks of HawkeyePedershaab massproduction systems is their ability to process two or even three sizes of pipe simultaneously, reducing pallet and mold investment as well as increasing plant flexibility.

In automated systems, HawkeyePedershaab provides sorting systems as the final step in the robotic pipe handling process to sort the pipe into like diameters for easy yarding by fork trucks.

HawkeyePedershaab offers two distinct solutions for this task, using either an overhead stockyard crane or a turntable coupled with three separate outfeed rails, allowing the customer to choose whatever system best fits his plant layout.

 

Features & Benefits:

  • High-speed sorting systems allow for buffering of pipe, preventing the fork truck driver from stopping the entire production line
  • Sorting pipe into like sizes allows for fast and logical fork truck activity
