1. SYSTEM DESCRIPTION
The Prolyte Tower & Ground Support systems are lifting tools where the load is constrained in its horizontal movement by means of a Sleeve block, that is build around, and lifted along, the tower sections. The ST-Tower has a loading capacity that is limited by the lifting machinery: 2000 kg for an electric or hand operated chain hoist. In general towers and ground support systems are used where the lifting of loads from a building structure is impossible, very expensive, or when traditional telescopic winch stands do not have a sufficient in load capacity. ST-Towers use a vertical mast of standardized S40T truss as compression absorbing elements, these have much better strength and stability characteristics than traditional stands.
2. LIMITATIONS OF USE
The ST tower system is to be used with Prolyte trusses only. Loads to the trusses and towers shall be vertical only, no side loading is allowed to the system. The ST system is designed as temporary lifting structure for indoor use only. When used outdoors or when horizontal loading is applied appropriate measures, such as placing guy-wires (cable-stays) and ballast, have to be taken to ensure stability. The ST system is to be built by competent and trained persons only. For all other applications contact your local dealer or Prolyte.
3. SCOPE OF USE
Prolyte's ST-towers are designed for the lifting of truss spans over stages, dance floors, exhibition area's etc, where equipment such as lighting-, sound-, drapes or decoration elements is suspended. This can either be a single (stand-alone) Tower, a Goal post configuration (two towers with a single span) or in a rectangular set ups with 4, 6 tower ore more.

Prolyte ST-Tower Manual Assembly Instructions The spans of the trusses must NEVER exceed permissible length or load values given in the loading tables for the specific type of truss. ST-towers are to be built to a maximum height of 12 m. The total weight on the tower including, load, sleeve block and trusses must NEVER exceed 2000 kg when using a chain hoist1. Prolyte-ST towers comply with the European Machine Directive and bear the CE-mark. ST-systems are designed for indoor use, for outdoor use please contact your local dealer or Prolyte.
WARNING
Prolyte ST-towers are not designed to lift people!
4. IDENTIFICATION
The ST-tower is composed of the following parts: 1. Mast sections S40T 12 kg/m 2. Base section ST-004 36 kg 3. Sort outriggers ST-011 3 kg Long outriggers ST-012 13 kg Stabilizer tube T-51-PI094ST 1,5 kg 4. Top section ST-009 25 kg 5. 6. 7. Hinge set CCS6-H Electrical chain hoist CH-SM10-1004 Chain for hoist Sleeve block ST-010 2 kg 45 kg 1,6 kg/m1 44 kg 27 kg 27 kg max. height 12 m made of steel hollow sections with castors short outriggers with screw jacks long outriggers with screw jacks Pulleys suited up to 8 mm chain links. Double pulleys optional. 4 hinges per tower needed WLL 1000 kg. Excluding chain. Chain 6.8 mm for hoist Suitable to fit all S-series truss. Lifting arm, which can lift the mast in an upright position with the help of the electrical hoist. A one m. furbished mast section. Can safe load from ground level. Place ST-SAFE as close as possible to top-section
Optional components: 8. Tower erecting system ST-HELP 9. Safety set ST-SAFE
The embossed ring on the ends of the conical coupler receivers, and stickers featuring the Prolyte logo can clearly identify the MPT towers and truss.
NOTE
Make sure the system is built only of genuine Prolyte components, which are clearly and positively identified as Prolyte products. Copies do exist, and even though they may appear to fit to Prolyte trusses, they do not have identical strength and safety characteristics.
5. DIMENSIONS & LOADING
The maximum allowable height of the ST tower truss modules shall be no more than 12 m. To this ca. 0,65m is added for the base section with the outriggers (~ 0,3m), the hinge section (~ 0,1m) and the top section (~ 0,25m). Therefore the maximum height of a 12 m ST tower will be approximate. 12,65 / 12,75 m, depending on the amount of extension of the outriggers screw jacks. The maximum allowable load to a ST-tower of 12 m is 2 ton (20 kN), this is set in relation to the maximum allowable height of the tower, and the absence of side loading or other kind of bending forces to the tower. The surface area per ST tower base will be approximate 1,2 x 1,2 m, using short outriggers (ST-011), and at least 2,1 x 2,1 m with the long outriggers (ST-012).
In systems composed of two (2) towers or more, all lifting the same truss or grid, it is mandatory in Dutch Law to reduce the lifted load to 75% of the rated capacity, thus max. 750 kg per tower with 1 ton chain-hoist or 1500 kg with 2 ton hoist or double reefed 1 ton hoist.
