Observe the product manuals! In addition to the points described here, all information in the section “Instructions regarding safety” in the other supplied product manuals also applies. |
|
|
Danger to persons if they are not trained! Special technical expertise is required to correctly sling and safely lift and move loads. Otherwise accidents may occur, which can cause serious injuries or death. Personnel working with the crane (e.g. crane operators and load handlers) must first have received instruction regarding operation and be assigned this work by the end user. |
|
|
Danger from load drop due to unsafe working! Suspended loads always pose a hazard when working with the crane. The load could fall and kill or injure people! Always keep your own safety as well as the safety of others in mind when working with the crane. The technical knowledge gained from the instruction and the supplied ABUS product manuals will be aid you in working safely with the crane. |
|
|
Danger of load drop caused by exceeding maximum load capacity! | |
|
|
| |
|
|
If the maximum load capacity is exceeded, the crane and the supporting structure could be damaged. This could cause the load to fall, killing or injuring people. Observe the maximum load capacity of the trolley and the crane and do not exceed it! | |
The maximum load capacity is specified on the trolley and on the bottom block or hook assembly. The maximum load capacity of the crane is also given:
─ For overhead travelling cranes: On the main girder
─ For jib cranes: On the jib arm
─ For HB cranes: On the crane girder
─ For single-rail trolley tracks: On the trolley track

Danger of load drop caused by exceeding maximum load capacity! | |
|
|
| |
|
|
If the maximum load capacity is exceeded, the crane and the supporting structure could be damaged. This could cause the load to fall, killing or injuring people. Observe the maximum load capacity of the trolleys and the crane and do not exceed it! | |
The maximum load capacity is specified on the trolley and on the bottom block or hook assembly. The maximum load capacity of the entire crane is also given on the crane itself:
─ For overhead travelling cranes: On the main girder
─ For jib cranes: On the jib arm
─ For HB cranes: On the crane girder
─ For single-rail trolley tracks: On the trolley track
─ If the maximum load capacity of the crane can be added together exactly from several trolleys, the load capacities of the respective trolleys are given with a “+”. The total is the maximum load capacity of the crane.
|
First 5 t trolley |
Second 5 t trolley |
|
| |
|
Total 10 t, maximum load capacity of crane | |
|
20 t trolley |
10 t trolley |
5 t trolley |
|
| ||
|
Total 35 t, maximum load capacity of crane | ||
─ If the maximum load capacity of the crane cannot be accurately added together from several trolleys, first the maximum load capacity of the crane is given, then the maximum load capacity of the trolleys, specified in brackets with a “/”.
|
Maximum load capacity of crane | |
|
| |
|
16 t trolley |
10 t trolley |
Additional rules:
If the maximum load capacity of the crane corresponds exactly to that of the largest trolley, the maximum load capacity of the crane and the brackets are omitted.
|
Maximum load capacity of the crane and, at the same time, of the largest trolley | |
|
| |
|
|
Maximum load capacity of the smaller trolley |
|
Maximum load capacity of the crane and, at the same time, of the largest trolley |
|
|
|
Maximum load capacity of the smaller trolleys |
─ In this case as well, the maximum load capacity of the crane can be added together from several trolleys.
|

|
Total 25 t, maximum load capacity of crane | ||
This section only applies if the main girder (for overhead travelling cranes), the jib arm (for jib cranes), the crane girder (for HB cranes) or the trolley track (for single-rail trolley tracks) are divided into different areas with different maximum load capacities.
|
|
Danger of load drop in partial load ranges! | |
|
|
| |
|
|
Depending on the position of the trolley, the crane will have different maximum load capacities. If the maximum load capacity is exceeded, the crane and the supporting structure could be damaged. This could cause the load to fall, killing or injuring people. Observe the maximum load capacity of the partial load range in which the trolley is currently located. Do not exceed the maximum load capacity! | |
The maximum load capacities of the individual areas on the main girder (for overhead travelling cranes), the jib arm (for jib cranes), the crane girder (for HB cranes) or on the trolley track (for single-rail trolley tracks) are separated from each other by vertical lines. The respective maximum load capacity of the partial load range is given within the lines.
|
|
Danger of load drop with heavy load lifting attachment! | |
|
|
| |
|
|
The weight of the load lifting attachments (e.g. crossheads) can be very heavy and thus reduce the maximum load capacity of the crane. If this weight is not factored in, the maximum load capacity of the crane could be exceeded, which could cause the load to fall and kill or seriously injure people. The weight of the load lifting attachment must be taken into account in the crane operator's decision of whether a load can be lifted with the crane. | |
This section only applies if the crane has a warning device (e.g. horn or bell).
|
|
Danger to persons if there is no warning! | |
|
|
| |
|
|
Especially when the crane operator is not standing directly at the crane (e.g. if using radio remote control), personnel standing nearby may not necessarily be aware that the crane is in use. This could result in dangerous situations where people can be killed or injured. Use the warning device (e.g. horn or bell) to warn persons nearby of suspended loads. | |
|
|
Danger of trolley falling if the load is pulled diagonally! | |
|
|
| |
|
|
If an attached load is pulled or towed at a slant (e.g. over the floor), the trolley can tip due to the lateral forces and fall. The trolley can also be damaged by wire ropes or chains running askew. This in turn means the load or crane could fall and kill or injure people! Always lift the load vertically only! Do not pull any vehicles or carriages! | |
|
|
Danger of trolley falling if a load jerks free! | |
|
|
| |
|
|
If an immobile or jammed load (e.g. due to rusted together or bolted together parts) is jerked free, the trolley could fall due to the strong jolt from the sudden release of the load. As a result of this people can be killed or injured. Do not jerk the load free with the crane. | |
|
|
Danger of trolley falling if a load is dropped! | |
|
|
| |
|
|
If a load in the load hook, the lifting tackle or the load lifting attachment is dropped and then caught with the crane (e.g. a component is only loosely suspended and then detached), the strong jolt could cause the trolley to fall. As a result of this people can be killed or injured. Do not attempt to catch loads! | |
|
|
Danger of trolley falling if a load is turned! | |
|
|
| |
|
|
If a load in the lifting tackle or load lifting attachment is rotated or turned, it can suddenly tilt. The strong jolt could cause the trolley to fall. As a result of this people can be killed or injured. Only turn the load if the crane is installed with a load lifting attachment specially designed for turning loads. | |
|
|
Danger to persons from transporting personnel! | |
|
|
| |
|
|
The crane is not equipped with the necessary safety devices to safely transport people. This means that persons could fall during transportation and be killed or injured. Do not lift persons either together with a load or without one. If any persons step onto the load or the load lifting attachment (e.g. climbing into a pallet cage or sitting on the crosshead), do not lift the load. | |
|
|
Danger to persons from load drop! | |
|
|
| |
|
|
If the load is not slung correctly or the lifting tackle snaps, the load can fall. As a result of this people can be killed or injured. Do not transport a suspended load above anyone. | |
|
|
Danger to persons due to swaying load! | |
|
|
| |
|
|
A load that swings too heavily from side to side can no longer be safely controlled. As a result of this people can be struck by the load and killed or injured. During crane travel and trolley travel, avoid swinging the load too much from side to side. Do not use inching operation (button pressed repeatedly in quick succession). | |
|
|
Danger of load drop if hoist limiter fails! | |
|
|
| |
|
|
The top hoist limiter (in wire rope hoists) and the friction clutch (in chain hoists) can be damaged if subjected to regular use, and will therefore no longer function if the load hook is run too high or too low. This in turn could damage the crane and the load could fall and kill or seriously injure people! Do not intentionally or under normal operating conditions trigger the hoist limiter or the friction clutch. | |
Note
If work needs to be performed near the highest or lowest hook position during normal operation, an additional backup limiter, which is regularly inspected, must be employed to avoid damaging the hoist limiter.
|
|
Danger to persons if the crane is accidentally operated! | |
|
|
| |
|
|
If the crane is inadvertently controlled by another crane operator while working on or with a load, the crane could move unintentionally. This could lead to dangerous situations and injuries. Keep the pendant control or transmitter within reach as long as a load is attached. Do not allow the pendant control to roll away on the mobile control. Do not set the transmitter aside. | |
|
|
Danger to persons if the crane operator's view is limited! | |
|
|
| |
|
|
If the crane operator does not have an unobstructed view of the load, persons could be hit by the load and be killed or injured. Only operate the crane when the load, crane and operating range can be seen in full, or when working together with a banksman. | |
