6.1.4 Documentation:
Method of the container jack anchorage and eventual jack modifications are
necessary to be documented by drawing documentation and stress analysis.
The equipment manufacturer has to elaborate the operation manual to the
equipment, in which the jack is used.
! WARNING
The jack anchorage to a structure must be solved so that the ridge bar is not
stressed by bend. Loading only by simple pulling or pushing forces is permitted.
Maximum force on the jack must not exceed maximum load capacity of the jack.
6.2 TEST PRIOR TO USE
! NOTICE
(1) At first go over again the previous Articles of this Operation Manual and make sure
that all steps were well done and all parts are safely mounted.
(2) Inspect visually the jack and anchoring in the structure whether they are without any
defect.
(3) Test the function of the jack by crank motion.
(4) Jack up and consequently lower the movable part of the structure. At the same time
verify whether the jack holds the load without slipping when lowering and stopping.
7 OPERATION AND MAINTENANCE
7.1 JACK APPLICATION
7.1.1 The jack is a single purpose device destined entirely for anchorage to structures
with the purpose of manual jacking up and lowering of movable parts of structures.
It can be used not only in current environment, but also in environments with
explosion risk in the event that there is the symbol of the protection type marked
on the label – see articles 2.3, 2.4 and 5.3 of this OM.
7.1.2 The jack is operated by a crank. Jacking up and lowering of a structure can be
interrupted in any lift height. A lowering brake and pawls system with forced mesh
in the crank ensure position stability.
7.1.3 By reason that the work with heavy loads can constitute unexpected hazard it is
necessary to follow all „Security principles“ according to Chapter 3 of this OM.
7.2 SAFETY WORK ENVIRONMENT
! WARNING
(1) The operating personnel must be demonstrably acquainted with this Operation
Manual; they must adhere to valid security and hygienic regulations and must be
qualified for operation of this equipment.
(2) When working with the jack the operation staff must be equipped with gloves and
appropriate footwear.
(3) When operating by more persons always one worker must be determined who is
trained in safety at work and is responsible for jack handling.
(4) Before starting the work, the operation staff must check up whether all work area is
safety and whether there is a possibility of eventual escape from the environment of
jeopardy.
(5) With a product load capacity of 2,5t and 5t, the cover with the product casing is not
sufficiently dimensioned in terms of "breakthrough", therefore any cover that could
cause a collision with gears must be repaired or replaced. If the product collides with
a falling, flying (object (rock slide…) that could sufficiently damage the covers, work
must be stopped immediately and the product inspected.
