Range of application:

• For short distances.
• If possible on suitable tracks, e.g. crane rails or steel beams.
• Movement of heavy loads in mining, steel industry, machine construction, bridge construction and the ship building industry.
• Use as a conveyor, when the load is moving and the Roller Skates are fixed.
• Often used on construction sites.

Characteristics of the series of model A:

• Strong, durable, long-lasting structure
• Suitable for narrow areas with a low base
• Load can be fixed on conveyor top plate
• Problem-free transportation depends on the smooth ground rather than the capacity of the conveyor.
• The load capacity data are calculated according to the resistance on the steel plate.
• It is recommended to run on steel plates on uneven surfaces.
• Asphalt or concrete floor does not have optimum bearing ground properties
• The resistance of the rollers to turning under load is between 3% and 7% of the capacity.
• Uneven ground increases the resistance to rotation and makes handling difficult.

Usage areas:

• Heavy mining applications tight area load handling
• In handling heavy loads such as bridges, steel carcasses, etc.
• Placement of machines in industrial buildings
• Running mobile cranes under load
• In the relocation of construction scaffolds
• Used for handling heavy loads that cannot be moved by human power.
