AccessThe Winch Rig needs to be a minimum of 120 mtrs from side of dam at 90 degrees from center. This allows a safe distance should the cable break, and allows an even wear on dam bank.
It is preferable to pull across the dam to reduce wear on cables and equipment, and dam banks, (saving overall cost to you, the customer). We endeavour not to pull over the back of the dam as this would place the Loader on the inlet, potentially breaking up the ground and allowing silt in the dam again , also not placing unnecessary stress on the back wall, as the Winch Rig usually ends up lower, due to topography. The Loader needs to be able to travel from the Winch Rig to the dam, to set up, then around the dam to the opposite bank, then it moves along the bank to locate the scoop for each load. The Loader does not need access beyond the dam bank, thus making the system suited to dams with poor access. The mud / silt is deposited over the dam bank towards the Winch Rig. The scoop needs a drop off to unload of 1.5 mtrs or more for maximum efficiency. |
SafetyDue to the immense power, and unpredictable nature of the cables, we require a 120 mtr clear safety area around the dam and machinery at all times while equipment is operating, there are NO exceptions!! (see diagram).
Cable breakage does occur although we endeavour to avoid it. Also missiles / projectiles and shrapnel from the cable, changing direction, skidding or breaking are not uncommon to land in this area at speed or from a great height, the operation will Stop (at your expense) until a safe environment has been restored. However we welcome viewing from a safe location by arrangement with operators and are happy to stop occasionally to view progress in the dam. We have an excellent safety record / history and intend to maintain it. |
