Applicable to a CE test, regular inspection or setup inspection.

1. Documents
During the inspection, the following must be present with the foundation machine:

  • crane book; 
  • certificates of cables, chains, hooks, blocks, etc.;
  • capacity table(s) with all possible combinations with the various radii and raked positions;
  • overall drawing;
  • operation, maintenance and assembly instructions;
  • electrical, hydraulic and pneumatic diagrams;
  • the EC declaration of conformity in accordance with the Machinery Directive (for machines first put to use in the EU after 1 January 1995);
  • for regular inspections, setup inspection, subsequent inspections and suchlike, the most recent inspection report.

2. CE test
If this concerns the CE test, if applicable the following should also be present:

  • if not stated on the hydraulic diagram: a list of all pressure settings. In addition, a list with the maximum pressures exerted by the external load in the cylinders used;
  • the calculation of the design factors in steel cable and chain systems;
  • a list of the nominal diameter of cable drums and runner wheels;
  • information/test reports concerning noise emission (place of operation and surroundings).

A test can only be performed once it has been established that the strength and stability calculations satisfy the set requirements. To that aim, the calculations must be submitted to Aboma for approval.

N.B. Usually, it is necessary for the client or a specialist engaged by the client to draw up a proposal for the overload tests to be performed. This test proposal must be submitted to Aboma in good time before the test date. After Aboma has established that the proposal is based on the submitted calculations, this can be used during the test.

3. Test load
The client provides the test loads and the tools for the test and places them close to the foundation machine. The test load may not be made up of parts which are not well connected together or have little rigidity.

3.1 CE test
A one-off test performed before first operation after having been manufactured or significantly repaired or modified. The test loads are equal to the loads according to the capacity table, plus 25%.

3.2 Regular inspection
A regular inspection which is performed to ensure the good condition in connection with safety and maintenance. The test load must be sufficient to test the various hoisting winches to maximum winch force. If the foundation machine does not have hoisting winches, the test is done with at least the nominal load at maximum radius. As a rule, this inspection is performed once yearly.

3.3 Setup inspection
An inspection which is performed to establish whether the machine is suitable for performing a specific job. In principle, no tests with test loads are performed for this.

4. Responsibility during tests with overload
In the scope of CE tests, overload tests must also be performed. The client must ensure that a specialist is present at the tests who is responsible for the performance of the tests with overload. Overload tests can form part of the following types of assignment:

  • CE test;
  • continuation of the CE test;
  • subsequent check for CE test;
  • inspection in connection with significant modification.
