Safety 2 Safety m WARNING Use of Ludwig Hook XL can be hazardous. Serious injuries to death. Avoidance: • To reduce the risk of personal injury or death, ensure that all users of the Ludwig Hook XL carefully read and follow these Operating Instructions and are properly trained in use of this device. 2.1 Symbols used The following names and characters are used for particularly important details in the operating instructions.
Safety 2.1.1 Signal Words DANGER indicates a hazardous situation which if not avoided, will result in death or serious injury. WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury. CAUTION indicates a hazardous situation which, if not avoided, could result in minor or moderate injury. NOTICE is used to address practices not related to physical injury. Safety instructions (or equivalent) signs indicate specific safety-related instructions or procedures. 2.
Safety 2.2 Area of use/limits to use The area of use of the LUDWIG HOOK‘s provides for use in combination with crane applications indoors and outdoors. The LUDWIG HOOK has been constructed in accordance with stateof-the-art technology and the recognized safety-related regulations. Nevertheless, its use can generate dangers to the life and limb of the user or third parties and impairment of the LUDWIG HOOK‘s and other material assets. 2.2.
Safety 2.2.3 Operation m DANGER Carelessness. Serious injuries to death. Avoidance: • Work with intended use, with safety and danger awareness. • Conditions, in particular those that impair safety, must be eliminated immediately. 2.2.4 Maximum number of load cycles m DANGER GEFAHR Hook breakage. Serious injuries to death. Avoidance: • After maximum number of load cycles (see chapter 8 “General points” on page 8 - 1) put the LUDWIG HOOK out of operation. 2.2.
Safety 2.2.6 Remote control m WARNING Radio frequency. • • 2.3 Use remote control only as a handheld device. Use of the remote is not permitted in a bodyworn configuration. Intended use The LUDWIG HOOK is a hook from which loads up to 2T (4,400 lbs direct tension) can be suspended. The LUDWIG HOOK can be unlocked using remote control, where the load is released without the need for anyone to approach the load, and to unhook it manually. Release is only possible when the load is put down.
Safety 2.4 2.4.1 Misuse Passenger transport prohibited m DANGER GEFAHR Passenger transport Serious injuries to death. Avoidance: • Do not lift / transport people! The LUDWIG HOOK is not suitable for the lifting of persons! Image 2-2 Person transport NOT permitted LUDWIG HOOK / 06/10/2020 / Ludwig System GmbH & Co KG; 83435 Bad Reichenhall, Germany / Tel.
Safety 2.4.2 2.4.2.1 Overload LUDWIG HOOK The LUDWIG HOOK must only be used for the lifting of loads within its payload limit. m DANGER GEFAHR Risk of hook breakage. Serious injuries to death. Avoidance: • Observe the maximum permissible load. There is a table for this purpose that shows the max. payload according to the type of slinging and the number of LUDWIG HOOKs (see chapter 5 “Load types” on page 5 - 1). 2.4.2.2 Breakage m DANGER GEFAHR Risk of rigging hardware breakage.
Safety 2.5 Application areas Here we can differentiate between three significant areas of application: • • • the slinging of a load in direct tension • (see chapter 5 “Direct tension” on page 5 - 9) the slinging of a load in indirect tension • (see chapter 5 “Indirect tension” on page 5 - 10) the slinging of a load with a lifting strap in choke hitch • see chapter 5 “Types of Loading/Max. Weights (Lifting Strap)” on page 5 - 4 2.5.

The owner and/or user is responsible for the original operating instructions: • • • being accessible for consultation at all times. is continuously availability at the site of use of the LUDWIG HOOK. will be forwarded to each subsequent owner. 2.7.
Safety 2.8 Personnel selection and qualification Any work on the LUDWIG HOOK must only be performed by reliable expert personnel. Use only trained or instructed personnel. The responsibilities of the personnel for operating and maintenance must be clearly laid down. m WARNING Personnel qualification. Measure: • Make sure that only appointed personnel sevice the LUDWIG HOOK. LUDWIG HOOK / 06/10/2020 / Ludwig System GmbH & Co KG; 83435 Bad Reichenhall, Germany / Tel.
Safety 2.9 Instructions for normal operation m CAUTION Radio frequency. Avoidance: • During transmit operation, to limit RF exposure all persons are to be 1.2 in (3 cm) or more away from the transmit antenna. 2.9.1 Take the safety measures m CAUTION Injury.
Safety 2.9.2 Carry out function checks see chapter 5 “Before starting work” on page 5 - 13 2.9.3 Barrier-free environment for radio remote control m CAUTION Establish radio contact. Radio contact between the remote control and the LUDWIG HOOK must be ensured at all times. Measures: • Ensure a fault-free and barrier-free environment. Image 2-4 Establish radio contact LUDWIG HOOK / 06/10/2020 / Ludwig System GmbH & Co KG; 83435 Bad Reichenhall, Germany / Tel.
Safety 2.9.4 Check radio frequency m NOTICE HINWEIS Check radio frequency. Measures: • Perform test. The user is obligated to perform a test before commissioning the LUDWIG HOOK from the closest distance to make sure that various different devices do not use the same radio frequency. This applies particularly when using two LUDWIG HOOK systems close together. m CAUTION Same radio frequency.
Safety 2.9.5 Create visual contact m WARNING No clear view. Serious injuries to death. We need to point out that the operator must always have an unrestricted visual contact of the load to be released and the slinging equipment, including the LUDWIG HOOK. Measures: • Ensure a clear visual contact. Image 2-5 Create a clear visual contact LUDWIG HOOK / 06/10/2020 / Ludwig System GmbH & Co KG; 83435 Bad Reichenhall, Germany / Tel.
Safety 2.9.6 Maintain a safe distance m DANGER GEFAHR Suspended load. Serious injuries to death.
