Delta Scientific Bollard Systems
8.1.3.1
Description. Delta models TT203 and TT210, shown in Figure 13, are 8- or 10-inch
(20.3- or 25.4-cm) diameter steel bollards that are 24 inches (0.61 m) and 30 inches (0.76 m) high,
respectively. They can be lifted into position either manually (60-pound (27-kg) pull) or
hydraulically. The compact size [8-inch (20.3-cm)] and ease of operation make this system
particularly well suited as either a stand-alone or as a backup to existing pedestrian gates in the
single post configuration. They can also be used to secure wide entrances when the cost for
installing larger systems becomes prohibitive.
Hydraulically operated bollards can be operated individually or in sets, with up to 24
bollards controlled from a single hydraulic power unit. Performance and cost data are shown in
Table 6.
