General Danger Notice
• Before carrying out installation or maintenance work on HOSCH Sprung Blade Scrapers, ensure that the
conveyor belt has been stopped and “locked-off”. Do not begin any work that has not been previously
authorised by a responsible works manager and co-ordinated with all the departments involved (such as
electrical engineering, safety departments, production department, operation department). Protective
clothing, in particular safety boots, gloves, helmet and protective glasses are compulsory.
• An authorised work permit from the relevant manager must be obtained prior to any welding and cutting
work. Make sure that appropriate fire extinguishing devices are available.
• When working at height, provide safety devices, for example scaffolds, railings, guard nets, safety belts.
The devices must have been installed or inspected by a specialised company and released, as fit for work.
• Prior to starting work, the serviceman is to consult the person in charge of site safety and establish the
conveyor environment as well as possible specific security instructions.
• Prior to operating the scraper, ensure that the site is completely cleared. All equipment or parts, such as
scaffolds, lifting gears, tools etc. should be removed from the area prior to restarting the conveyor belt.
Guards etc. that may have been dismantled to ease the installation/maintenance must be refitted.
• HOSCH Sprung Blade Scrapers are generally equipped with shock absorbing elasto-mounts. During the
operation, unexpected bouncing movements may occur. Be aware of the nip points! The site operator
should guard the mountings to prevent accidental contact.
• The blade and module cleaning tips are already sharp when delivered. As the risk of injury during
installation or maintenance is very high, protective clothing is compulsory. Prevent the scraper from
unintentional pivoting.
• Due to the friction occurring during operation, the blades or module tips are likely become very hot.
Touching them immediately upon stopping the belt can lead to serious burns.
• The contact between the blades or modules and the running of the conveyor belt can create electrical
charges, sparking may also occur through discharge. Be cautious!
• Mineral or metallic particles may collect on the belt surface and cause sparking when passing the blades or
modules.
• All scraper parts, especially the components situated in the product flow, are subject to extreme wear. The
wearing of the component material may cause sharp edges. The risk of injury is high if this occurs.
• The weakened structures of worn parts are likely to break. To guarantee the personnel and conveyor
safety, these parts have to be replaced with new ones.
• Scraper systems are exposed to high dynamic stress. Therefore, all screwed connections are to be checked
and secured before each commissioning and upon each maintenance. Security elements (spring washers,
counter nuts) should not be re-used. They must be replaced by new parts. In case of mechanical damage
e.g. corrosion, new parts are to be installed.
• Only original, genuine HOSCH parts should be used.
