C4 - C6 Removing Ballast with Your own Equipment Video

Preparation

• Make sure the machine is supported on the outriggers in a square configuration, with the tracks just above the ground and no load on the hook.
• Make sure there is enough room for the extended boom on one side, preferably the right side, so the ballast is removed on the left side (because the sensors are on the right side).
• Make sure the tracks are retracted.
• Make sure the boom is horizontal.
• Make sure the ballast is placed in a safe spot, not on walking or driving paths and not within the working range of the compact crane, other machines or workers.

Step-for-step

• Set boom crosswise on the machine with the ballast on the left side of the machine (see figure 1).
• Slide ballast out (see figure 2).
• Take the ballast support out of the storage position and mount and secure it in the ballast removal position (see figure 3).
• Remove the rear cover of the boom with a 10 mm Allen key (see figure 4). 
• Slide the boom out slightly and switch off the control (see figure 5).
• Attach the ballast removal cable (see figure 6) to the back of the outermost sliding boom section with a bow shackle (see figure 7).
• Affix the other end of the ballast removal support with the locking pin (see figure 8). Make sure the cable is not twisted and does not have any loops/windings.
• Switch on the control and slide the boom out until tension is just applied to the ballast cable. Make sure the ballast cable is routed correctly over the cable sheave (see figure 9). Also be careful that the front of the boom does not contact anything (see figure 10).
• Use a 24 mm spanner to remove the two hex bolts that hold the ballast retainer in place (see figure 11). Remove the silver coloured plate that was held by the bolts.
• Slide the boom out slightly until the ballast is completely supported by the cable (see figure 12).
• Slide the ballast frame completely in; the ballast is now hanging free (see figure 13).
• Turn the ballast a quarter turn and lower the ballast by sliding the boom in slightly; make sure the ballast does not come into contact with the machine or the outriggers (see figure 14). Make sure the bow shackle on the ballast cable in the rear of the boom does not go over the cable sheave (see figure 15).
• Take off the ballast removal cable and fit the rear boom cover (see figure 16).
• Store the ballast retainer with the corresponding bolts and the ballast removal cable with bow shackle and the tools in a safe place, such as the toolbox on the machine.
• The machine can now be positioned in the transport mode and driven off of the ballast.

Check

• Check whether the ballast has disappeared from the display on the remote control.
• Check whether the ballast is in a safe position, move if necessary and/or cordon off the area around the ballast to prevent accidents.
