| The Tower | ||
| Height: | Maximum tower height of the tower payload mounting bracket is 80 feet (24.38 meters) above the ground as deployed from a trailer mount, with stowed height of 11 feet (3.35 meters) plus payload. The tower can be stopped and utilized at any desired height between its stowed and maximum height. | |
| Payload: | Maximum tower payload capacity is application dependent. For most applications, however, the payload is established at 2,000 pounds (907 kilograms) for an 80 feet (24.38 meters) tower height. | |
| Construction: | The tower lattice chain sections are constructed of 6061-T6 aluminum extrusions assembled with robust bolts and rivets. During deployment, heavy cast stainless steel hooks engage and rigidly attach the individual tower sections together in the triangular shape. Key tower technologies are protected by patents. Heavy mounting brackets are provided as standard equipment at the top of each of the three tower corners for attaching customers' equipment using 1/2 inch (1,27 centimeters) diameter bolts. | |
| Deployment & Retraction Speed: | From the towers stowed height, an electric motor/gear drive system will self-erect the tower to a height of 80 feet (24.38 meters) in approximately 5 minutes “at the push of a button”. By releasing the button, the tower can be stopped (and held by the brake) for payload utilization at any height between the stowed and maximum limits. | |
| Drive: | Either an AC or DC electric drive gear motor is offered, both of which include a heavy duty brake that is rated for severe conditions. No active power is required once the tower sections have been raised to the desired height and automatically secured by the brake.. | |
| Power Source: | An appropriate AC or DC electrical power source is required only for use when when raising or lowering the tower. This source may be a customer supplied power or one of Tower Solutions’ available power options. | |
| Emergency Crank Down: | The tower is equipped with an emergency manual crank down or up system. If conditions permit, a customer supplied battery-powered electric drill can be substituted for the crank. | |
| Enclosures: | All electrical controls are enclosed in drip proof enclosures. During tower deployment or retraction, the slowly rotating bales of the tower sections are contained within the tower frame, but not fully enclosed. | |
| Standard Leveling System: | A level sensing system notifies the operator with an indicator light when the unit is level within +/- 1 degree. In addition, bubble level units are located at each corner of the trailer to further facilitate the leveling process. Each unit has four drop leg, leveling jacks attached to the trailer frame. | |
| Remote Tower Control: | The tower is actuated by UP and DOWN buttons located on a corded remote control pendant attached to the main electrical control box. A 25 foot (7.62 meters) long control cord allows the operator to facilitate tower deployment and retraction from remote locations. | |
| Access Catwalk and Ladder: | Standard access to the customer equipment-payload on a retracted tower is provided by a non-skid catwalk. This catwalk offers access from the back side of the payload from a rear mounted ladder on the trailer. | |
| The Outrigger System | ||
| Description: | The outrigger system consists of four tubular assemblies that attach to the corners of the tower trailer frame and extend jacks out 14 feet (4.27 meters) diagonally from the tower vertical centerline, creating a 16 feet-8 inch x 22 feet (5.08 meters x 6.7 meters) support pattern. The outriggers are easily assembled on-site as part of the unit set-up. The outrigger system can accommodate +/- 18 inch (46 centimeters) variance in ground surfaces. When not in use, the outriggers are stored in brackets on the exterior of the tower frame. | |
| The Trailer | ||
| Description: | The tower and outrigger assemblies are mounted on a heavy double axle steel trailer. The trailer is equipped with:
| |
| General Features | ||
| Color: | The standard unit is delivered with the trailer and mechanism tan in color and the tower in natural aluminum. Standard product identification, instructional, safety and operational information decals are strategically applied to the unit for operator convenience and safety. | |
| Overall Size: | For the PTC-100, the retracted footprint is approximately 102 inches (2.59 meters) wide x 212 inches (5.39 meters) long x 11.5 feet (3.5 meters) high, not including tower payload or the trailer hitch. Total approximate weight less customer payload is 8,500 pounds (3,856 kilograms).
For the PTC-200 special tower, the retracted footprint is approximately 102 inches (2.59 meters) wide x 11.5 feet (3.5 meters) high, not including tower payload or the trailer hitch. Trailer length and approximate unit weight will be dependent on customer requirements. | |
| Special Tower Combinations | ||
| Lighting Array & Antenna Payload Mounting: | PTC towers can be equipped with a specially designed payload mounting frame that will accommodate multiple antennae along with four to ten metal halide sports lighting style fixtures. The lighting fixtures can be individually aimed and are controlled by a breaker switch located in the main electrical distribution panel. | |
| Surveillance & Antenna Payload Mounting: | PTC tower can be equipped with platforms of bars for mounting cameras and other surveillance sensors, along with mounts to support multiple types of antennae. | |
| Enclosures & Shelters: | Climate controlled optional enclosures can be made available to house and/or protect electrical components, isolate sensitive equipment and/or store special equipment.
Shelters for operators and/or control panels are also optionally available. These shelters can be equipped with insulation, full HVAC systems and electrical wiring to meet customer specifications. | |
| Options | ||
| Generator Sets: | Diesel (or gasoline) generators ranging in size from 4 Kw to 50 Kw. | |
| Many options are available to meet specific customer requirements. | ||
