Low Profile Loader


Hard-Line’s LP401 is a remote control operated low profile loader (skid steer) that can be used in a variety of restrictive areas where a normal man-operated machine cannot operate.

A safe and easy way to collect or move ore and clean. The machine has been developed following mine requirements and user needs.

Applications include: culvert cleaning, conveyor cleaning, military missions, building defensive berms, push blasted ore, removal of spillage, removal of materials, cleaning slopes after blasting, mucking operations in thinly bedded deposits, pushing ore, and carrying ore.

• Fully remote controlled operation

• Low profile for restrictive areas

• Perfect for hazardous areas

• Extremely flexible for use of operation

• Can be used with any standard skid steer attachment

• Can be operated by radio remote (operator line of sight)

• Can be operated by radio remote with video option (extended line of sight with camera)

• Can be operated by tele-remote (camera operated only, no operator line of sight)
