The Besser Easy Base (E-Z) manhole form set is engineered to deliver precast production efficiency by making setup, pouring and stripping easy, economical and labor-saving. Flexibility is key! Form sets can be tailored to individual production needs and adapted to various diameters and lengths. Base configurations may be the standard extended style or with optional roll-back wheel assemblies. E-Z Base operation is clean and simple, involving one person and one crane.
Once the reinforcing cage is in place on the core, a turn of an actuator locks both the core and step pins into the pouring position. The actuator is located on the outside of the form set for easy access and is linked to the core by a gear assembly. The form (jacket) is next lowered over the core and pallet and locked into position, completing the setup.
Forms can be one or two-piece in design, and both styles can incorporate quick-adjust rollover trunnions. By simply pulling one pin, the producer can adjust the trunnion for varying product heights. This adjustability allows the producer to easily roll the balanced form over, either empty or full. To further accelerate cycle times, forms with optional roll-back wheel assemblies are available.
Pouring is simplified with the E-Z Base form set. The core, pallet and shoveling plate are all attached to a portable, heavy-duty stand. This arrangement reduces cycle times as repeated handling of these components is eliminated.
After proper curing, the product is ready to strip. A turn of the actuator collapses the core and retracts the step pin assemblies. At the heart of this internal operation is the Besser core collapser, recognized throughout the industry for its simplicity, durability and efficiency.
The form and product are raised and rotated to the stripping position utilizing the rollover trunnions. The lock assembly is actuated to open the form, the finished product is removed and the production process is complete.
The result? Quality manhole products made with shorter setup and stripping times, with an overall reduction in labor costs. Efficient E-Z Base form sets are another reason that producers are turning to Besser for their wet cast precast product needs.
