Power Supply Replacement ZAP replaced one of three existing power supplies serving the three glass melters. The existing 1.8MW power supply was replaced with a new 3MW variable voltage transformer and a new MV vacuum contactor and disconnect switch was installed to feed the new transformer. ZAP evaluated the existing steel structure for the installation […]
Outside Hopper Structural Support ZAP developed an engineered repair plan with a repair sketch for a self-supporting Lime Hopper which was struck by a moving vehicle and sustained substantial damage to a column, vertical bracing, anchor bolts, etc. ZAP completed a site visit to determine the extent of the damage and complete the repair sketch.
Edge Trim Hopper ZAP completed the engineering for the replacement of the client’s edge trim re-feed hopper, blowers, and transport lines at their facility. ZAP’s design included an increase to five outputs metered using blow-through rotary valves, continuous hopper level monitoring using a laser distance sensor, five individual positive displacement blowers, the design of a […]
Relocated Silo, Foundation Design, and Permit Support: ZAP performed NFPA study to determine the appropriate location of the relocated silo with respect to the deflagration vents located on it and an existing adjacent silo.
Monorail Addition at Roof A manufacturing customer wanted to add a new monorail and increase the capacity of existing monorails supported by the building roof trusses above their process equipment. ZAP provided analysis of the existing trusses, which had already been reinforced when monorails were first added. The customer requested modifications to our design based on […]
A steel manufacturer operates two 200-ton bridge cranes in their melt-shop for daily operations. For production and safety improvements they requested ZAP design fixed access platforms at each end of the building so that the cab operator could wash their own windshield periodically during shift. The original building had been modified and the original crane had been replaced since design drawings were produced. Our design efforts for this scope were complemented by a 3D scan of the facility for a higher confidence that our design had taken as-built conditions into account.
Central Vacuum System A manufacturing facility seeking to improve silica dust cleaning operations requested ZAP design a central vacuum system to cover critical areas of their seven-story crushing and screening building. For a more complex manifold layout through such a congested space, ZAP was able to provide a laser scan of the facility and design […]
A manufacturing customer is replacing specialty transformers across many of their plants and the new model is heavier than the unit that had been installed before. The installation is taking place on the sixth floor of their production facility
