Safety Instructions; Maintenance - unicraft A Benutzerhandbuch

INTRODUCTION:
Read these safety instructions carefully in addition to the instructions for use,
operation and maintenance. Keep them in a safe place for later consultation.
This crane has been designed for use as a hoist with extensive use in industry
and garages, particularly in the handling of engines. Any other application
beyond the conditions established for use of this crane will be considered
inappropriate.
Handle the crane correctly and ensure that all parts and components are
in good condition and that no parts are missing. Take special care with the
elevation accessories used with the crane, such as slings, supports, compen-
sators, etc.
The crane should only be used by authorised persons, having read carefully
and understood the content of this manual. Do not modify the crane in any
way. Non-compliance with these instructions may result in injury or damage
to the user, the crane or the load to be lifted.
The manufacturer accepts no responsability for the improper use of the
crane.

1. SAFETY INSTRUCTIONS

1.1. The load to be lifted should never exceed the rated capacity of the
crane in each of the positions of the hoisting arm.
1.2. Ensure the element to be lifted against any type of slipping. Do not
aplly any lateral pressure tothe elevated or suspended load.
1.3. The crane should be supported on a solid, level and horizontal, non-
slip surface. It should be well illuminated and free of unnecessary obstacles.
1.4. The capacity of the crane is reduced as the is extended. For make sure
that the load capacity is never exceeded in each of the positions of the slide,
as indicated on the adhesive label.
1.5. Both children and unauthorised persons should be kept away from the
work area. During the work, ensure that there is nobody in its path.
1.6. Prior to proceeding to work with the crane, make sure that the slide is
perfectly fitted (Picture 1). The crane arm should be located in the nearest
possible position to the load to be elevated. Make sure that there are no
elements in the vicinity which hinder the elevation of the load or obstacles
which prevent its lowering. When securing the load to the hook, always use
appropriate elevation elements with a capacity superior to that of the load to
be elevated. Check that the safety trigger functions correctly.
1.7. To lift the load in a stable and balanced way, suspend it from the hook
and bear in mind that its centre of gravity should always be within the crane
support base.
1.8. Never allow the load to sway or lower it brusquely as this may prove
to be dangerous.
1.9. Do not place any part of the body under the elevated load, and do not
climb on top of the crane.
1.10. The crane is not a transportation element but in the event that it is
necessary to move the load a short distance, position the arm of the crane
in the lowest possible position. Once the movement has been completed,
place the load on the ground. The crane is not a device to maintain the load
elevated for an unlimited period.
1.11. As a safety measure against overload, the crane is fitted with an over-
load valve, set at its maximum working pressure at the factory. This valve
should not be tampered with under any circunstances.
2. ASSEMBLY, USE AND OPERATION
As we are handling heavy elements, it is essential to carry out the following
assembly processes with the help of other people.
2.1. Break the box and assemble the wheel brackets on the column.

2.3. To assemble the legs in CRP models, place the crane on the ground and
introduce the rivet (9) and the screw in the position indicated in the first picture.
2.4 By last, place the auxiliar wheel bracket with the provided axles and rings.
Only necesary in CRP models.
2.5. Prior to using the crane, the hydraulic circuit needs to be drained in order
to eliminate any air from the valve system of the hydraulic unit. Turn the hydraulic
group knob 90º while pumping the lever several times. By releasing the knob
the crane is ready for use. Turn the hydraulic unit to work in the most confortable
position.
2.6. To lift the load, activate the lever. If lifting an engine, secure it at the points
recommended by the manufacturer.
2.7. If it is necessary to use the crane in other positions, the slide should be
perfectly fitted.
2.8. To lower the load, turn the knob. This system enables the lowering to be
regulated and controlled manually and precisely. As another safety element, the
crane is fitted with an LCS system to avoid brusque lowering, resulting from a
possible incorrect manoeuvre. The crane will stop the lowering process when the
knob is not activated.
2.9. When the use of the crane is completed, the piston of the hydraulic unit
should be fully retracted. First move the slide to its initial position.

3. MAINTENANCE

Important. Both the maintenance and repair of this crane may only be carried out
by qualified and authorized personnel, who as a result of their training and expe-
rience are familiar with the hydraulic systems used in these devices.
3.1. Clean and lubricate the axes of the moving parts of the crane at regular
intervals. The crane should be kept clean and protected from aggressive condi-
tions at all times.
3.2. Only original spare parts should be used.
3.3. Withdraw the crane from service if it is suspected that it has been subjeted
to abnormal loads or has suffered any type of knock until the problem has been
resolved.
3.4. If the oil level needs to be checked or refilled, dismantle the hydraulic unit
and with piston fully retracted, remove the filler plug and drain its contents into
a container. With the hydraulic unit in a horizontal position, proceed to introduce
the necessary volume for each model as indicated. Avoid the entrance of any dirt
with the new oil.
Important
. An excess of oil over the volume required may affect the operation
of the crane.
3.5. Only use hydraulic oil, HL or HM type, with an ISO grade of cinematic visco-
sity of 30cST at 40º, or of an Engler viscosity of 3 at 50ºC.
Extremely important
. Never use brake fluid.
3.6. When the crane is not in use, it should be fully retracted in the lowest position
so as to minimize piston corrosion. It is recommendable to aplly an anti-corrosion
product to tje main piston and to the pump.
3.7. Store the crane in a dry and clean place, out of the reach of children.
3.8. At the end of the useful life of the crane, drain off the oil and hand it over
to an authorised agent. Dispose of the remaining parts in accordance with local
regulations.
3.9. Both the repair kit, wich exclusively contains the retainers and joints, and
the spare part sets, must be ordered using the reference assigned in the table.

the arm using the provided axle. Make sure that
the rings are correctly placed.
