Barge cranes: Safety instructions
Barge crane with suspended vehicle
These safety instructions are absolutely mandatory!
Despite keeping safe distances and the installation of safety equipment, there are still residual risks associated with a ship’s crane.
In ship’s cranes where the space underneath the load-handling attachment can be seen by the operator, it is generally not necessary to provide for barriers. However, the importance of increased awareness must be pointed out to the operator. He has to ensure that no person or object is under the load-handling attachments.
- The ship's crane may not be loaded over its specified load capacity.
- Any kind of application or operation that impairs the safety of the ship's crane must be avoided.
- The operator is obligated to report safety defects immediately.
- The user may operate the ship's crane only in a perfectly working condition.
- Unauthorised modifications and alterations are not allowed.
- Moreover, local safety and accident prevention regulations apply for the operation of the ship's crane.
- The boom must always be stowed in the mounting for this purpose and secured against unauthorised use.
Testing, servicing, operation and maintenance
- The ship's crane may only be repaired by employees of Büter Hebetechnik GmbH.
- When any work regarding the commissioning, operation and servicing is done, the instructions and notices specified in the operating manual must be adhered to.
- When hydraulic cylinders are replaced, make sure that the pipe rupture valve, the lowering braking valves and/or the check valves from the old cylinders are screwed into the new cylinder. The factory settings of the valves may not be changed!
- When a high-pressure filter cartridge is replaced, the cylinders must be depressurised.
- It must be checked if all safeguards are in place after repairs have been done.
- The safety equipment must be tested after repairs.
- The boom must be inspected once a year by a qualified person. This inspection is then documented by the expert in the crane inspection report.
- Hydraulic lines, hydraulic hoses, and the crane cable must be checked regularly (at least monthly) for damage; damaged parts need to be replaced with new ones without fail.
- Control stations (operator panel, foot switch) must be positioned in such a way that the operator
- can activate the control mechanisms without hindrance.
- is not endangered by the load, the movement of the ship's crane or by any part of the ship's crane (the controls should be about two metres away from the ship's crane).
- is not at risk of falling.
- can monitor the load-handling attachment and the load during all movements, and have an overview of the space underneath the load-handling attachment and the load.
Fastening the load
- The load must be secured against slipping off the crane hook.
- Standing under the suspended load and in the swivel range of the ship's crane is prohibited.
- Only approved lifting equipment may be used.
- The crane may only be swivelled at a boom angle from approximately 25°. This will prevent a collision between the boom and the wheelhouse.
- Loads must not be pulled up diagonally. The load may also not be pulled by turning the ship’s crane.
