5 Sheet: DM General Information 1.3 Enclosure and plumb lines measuring The well dimensions have to be rectangular and vertical. All of the well dimensiones contain construction tolerance and the well dimensions are rated dimensiones. The well dimensiones shall be possible with +/- 15mm. As a first step for installation, the whole shaft must be measured in all its length. In order to fix the plumb lines in the enclosure s upper part, a structure must be built. The lines will hang from said structure, at a clearance between guiderails lower than 20mm. After controlling the exact position of plumb lines, the lines must be fixed stably in their lower part to avoid any oscillation during the assembly process. Lower part fixing must be done in such a way that the plumb line may slide while the plumb is still in tension. WALL FIXINGS As standard solution for fixing the brackets on the shaft wall, a mixed type based on both dowels (on concrete) and threaded bars (on blocks) is advised. Both elements will be supplied with the lifting platform in a suitable quantity. All brackets are provided with slots 11 x 25 especially for these two elements (according manufacturers instructions). In case the shaft walls are both on concrete (generally the building slabs) and blocks, the dowels will be fixed to the concrete slabs and the threaded bars to the blocks. Please note the appearance of dynamic loads. Please note current advancements and international approved rules and validities by the building authorities especially in the field of dowels. plumb lines 10 guiderails guiderails shaft bottom

8 Sheet: DM Placing of guiderails starting edge The illustrations in this manual correspond to the assembly of the standard mechanical configuration. Assembly of a reinforced mechanical configuration is identical although the number of joining element s may vary in some areas. Place the guiderails starting edge in the pit, centering it with the guiderails plumbs. Fix the edge to the floor with expansion plugs. Screw in the Tecnikit.

9 Guiderails assembly Sheet: DM Guiderails assembly First, it is necessary to make the holes on the walls, fix the plugs and then the guiderail corner iron. Once the guiderails are fixed, measure the distance between them and their alignment; admissible tolerance is ± 1mm.ximage. Srews in the Tecnikit. In case of reduced shaft space, the plug will be rotated 180º in comparison to image. distance between guiderails Guiderails assembly

10 Sheet: DM Stand assembly Screw the stand to the guiderails starting edge and position it as specified in the installation plan. Check the Stand s verticality at all times.. 90º 90º

11 Sheet: DM Cylinder installation The cylinder is introduced into the passageway. A mounting sling is placed in the cylinder s upper part as shown in the figure. Then the piston is elevated by means of a block and tackle and left resting on the stand s upper part. Place the first clasp in the cylinder s upper part and fix it to the enclosure s wall with two expansion plugs or through studs checking that they are vertical and parallel to the guiderails In case the cylinder comes in two segments, the second fixing point will be in the lower segment and as close as possible to the joint. Screw bag code If the installation cylinder has two or more segments, please refer to the Wittur Hydraulic Drives installation manual.

12 Sheet: DM Installation of rupture valve The piston head lid has an outlet to drain the oil adhered to the plunger when it moves up and gets removed by the dust scraper when the plunger moves down, in order to prevent that in case there is dust as is usually the case- it may go dirty into the oil circuit. In this outlet, an elbow and an oil collection hose are placed. The hose is plugged to a collection container. Once this is done, place the rupture valve and position the piston controlling its perfect verticality. The rupture valve has a seal and four screws for fixing purposes. First, place the seal and position the rupture valve according to the direction the pipeline will follow (upwards, downwards or to any of the two lateral sides, at 90 between each other). Once in position, fix the valve with the screws and then put the piston in its correct position. This is done by spinning the piston on its own axis (after loosening the piston s support clasp) until the rupture valve is located within the 90 angle formed by the position of the closest valve to the nearest guiderail (1) and the position closest to the support wall (2). The most convenient location is, within this angle, at 30 of the guiderail line (3). 90º 3 0 º

13 Sheet: DM Fixing the head The head is placed on the cylinder with the return pulley using the screw that comes with the plunger. Assemble the head s guideways, adjust them and center them in the guiderails. NOTE: To protect the cylinder from brickwork inside the elevator s enclosure, it is convenient to protect the upper part (head) with compact grease to prevent solid particles from entering in the space between the oil scraper and the plunger. When performing welding jobs in the elevator s enclosure, check that the plunger is into the liner or at least protected from sparks sparks may cause damage to the plunger s surface which in some cases might be irreparable.

14 Sheet: DM Installation of central unit and oleodynamic drive First, assemble the metallic cabinet supplied in parts. Place the full piece in its definite position. Next, the electric lines and hydraulic pipeline are laid out. The connection between the central unit valves set and the cylinder valve is made with a flexible tube when the length between them does not exceed 14m. In case length is bigger, a flexible tube is placed in the central unit s outlet and a rigid tube goes into the cylinder s inlet. Finally, the circuit is filled with oil. The objective is to fill the volume occupied by air with the same oil volume, then expelling the air without turbulences, bubbles or airoil mixing. The correct filling and purging of the circuit will prevent to a great extent problems to adjust the valves set and the elevator s comfortable performance. Flexible connection Rigid connection
