Sandvik Load and Haul has developed a Proximity Detection System Interface for its underground loaders and dump trucks. The feature allows installation of a third-party Proximity Detection System (PDS) to a Sandvik loader or dump truck to meet legal requirements and improve safety in underground operations.
Proximity Detection Systems (PDS) help to improve safety at mine and construction sites where risks of collision may occur. The PDS is generally designed to slow down and/or eventually stop the equipment in case the system detects a person or an object carrying a tag inside a predefined zone. The exact operation of the PDS always depends on the selected system and the local conditions, which vary from site to site.
Marjut Seppälä, Product Safety Manager, Load and Haul, comments Sandvik’s PDS Interface: “A PDS is a legal obligation in South Africa, which is an important market area for Sandvik. We have developed the interface to meet these requirements, and at the same time to improve safety on our customer sites. As we want to provide the same opportunity for all our customers, regardless of the market area, the interface now becomes globally available for our loaders and trucks,” she continues.
“But even though Proximity Detection Systems help to improve safety, they shall never be used to replace normal safe and sound operating practices.”
The PDS Interface comes together with another safety-enhancing feature, Speed Brake Interlock, whose purpose is to prevent excessive speed during driving. When the Speed Brake Interlock functionality is in use, it monitors the equipment speed and guides the operator to slow down by means of visual and audible messages on the system display.
