Dear User,
The Demolition grab is a piece of equipment for excavators. The demolition grab is
available in various weights, capacities and versions and is always a fast and purpose-
built demolition device.
It is imperative you read this manual and follow all the instructions given when
working with our machinery in accordance with our recommendations.
The demolition Grab products are provided with a CE marking, thereby complying with all
the necessary European regulatory safety regulations.
It is essential to follow the safety regulations at all times.
These safety regulations refer to those laid out in this manual, including both the
operating instructions for excavators and the safety regulations that apply to the vicinity in
which the demolition grab product is being used, maintained and repaired.
Modifications made to the Sorting Grab may only be implemented with the written
consent of Hydraram. Only under these circumstances do the warranty conditions and
CE liabilities remain applicable.

meets all the required machine guidelines (Guideline 2006/42/EC, as most recently
updated as well as national legislative implementation of this directive.
Attention: Any adjustment that is made to this product without written consent on
Hydraram, makes this declaration void and invalid.
We should draw your attention to the fact that the demolition grab product is designed to
be assembled with another machine, and that the product, on the grounds of the
machine Guide Line, can only be used once the whole machine is in accordance to the
conditions laid down by European regulations.

Warning
Never work on the hydraulic system if the system is still under pressure! Keep hands
away from moving parts at all times.
Hydraram cannot anticipate every possible circumstance that might involve a potential
hazard. The warnings in this publication are, therefore, not all–inclusive. If a tool,
procedure, work method or operating technique that is not specifically recommended by
Hydraram is used, then you must assure yourself that it is safe for you and others.
You should also ensure that the product will not be damaged or made unsafe by the
operation, lubrication, maintenance or repair procedures that you choose.
Safety Regulations
The demolition Grab should always be attached to an excavator of the correct weight,
class and capacity of machine. Refer to the data information plate on the grab and
consult the technical specifications in this manual. When in doubt contact the supplier.
The weight of the grab, increased by the weight of the load being picked up, must never
exceed the maximum allowance of lifting power. For further information consult the
excavator manual.
It is prohibited for people to be within the rotation range of the machine and grab. Keep in
mind that material being lifted that extrude from the grab will enlarge the rotation range.
It is always possible that material can fall out of the excavator’s grab. For this reason,
never rotate the machinery above people, machines nor vehicles.
Always pick up a long load at its centre of gravity, to prevent the excavator from either
rotating or tipping over. It is not permissible to use the grab to hit or pound.
Whilst connecting or disconnecting, lubricating or other maintenance work, the grab must
be stable and on a flat surface. Before performing lubricating or other maintenance work
the engine should always be shut down.

Terms of Guarantee
Hydraram provides a warranty of 12 months from the date of delivery.
All defective parts proven to be caused by faults in either manufacture, production or
material are covered by the warranty.
Defective parts that are replaced and fall under guarantee become property of Hydraram.
They must be kept available and returned immediately, in complete and unaltered
condition, upon the first request from Hydraram.
Any claim made under guarantee will only be taken into consideration once a written
appeal is made to the dealer or Hydraram. This must be done directly after the damage or
fault occurs and at least within 24 hours of any irregularities and problems arising.
All claims under conditions of the warranty must contain the following data; the type of
machine the product has been mounted on, the serial number of the grab, the record of
the defective part(s and a description of the fault, photographs, copy of the delivery
papers and invoice and a copy of the invoice of the piece of equipment concerned.
Minor repairs can be carried out in consultation with the dealer; the necessary parts
which fall under the warrantee, will be delivered without charge. For larger repairs the
grab should be sent to your dealer or Hydraram for repairs or modifications. The work and
necessary parts are free of charge. However, transport costs and call-out charges to and
from your dealer or Hydraram are not covered.
The Hydraram is not liable for consequential loss caused by a defective demolition
Grab (consequential loss to excavators, consequential loss due to a stationary excavator
or the suspending of work activity).
Excluded from Guarantee:
•Damage caused by faulty assembly of a machine and or the hydraulic system,
improper maintenance without expertise and transport damage.
•Defects resulting from improper repairs and/or maintenance including that carried
out by an unauthorised third party.
•Defects arising from neglect or improper execution of preventive maintenance
procedures e.g. regular lubrication or greasing.
•Defects to parts which are subject to normal wear like blades.
•Consequential loss caused by failure to replace normal wearing parts in time
N.B. If defective or worn down parts are replaced by non-original parts, the entire
warranty and liability will cease to apply.

Before taking the machine into operation and to ensure the good functioning of the a-
pparatus, it is important that the following points are checked and correspond to the tech-
nical specifications as shown on the information plate and in the manual.
•The type and weight of the sorting grab must conform to weight and machine class
of the intended excavator.
•The oil flow and the pressure for rotating the demolition grab should be checked and
adjusted.
•Beware: the return pressure of the rotating oil at a continuous level may be at a
max-imum of 25 bar, and only briefly (maximum of 10% of the working time) at 100
bar.
•The oil flow and pressure of the pinching (opening and closing) of the sorting grab
needs to be controlled and adjusted.
•Check if the hydraulic quick release hitch is in good order and screwed on firmly.
•Check if the ball valves and valves are in the correct position
•Check if the connecting pins between the excavator and the sorting grab are well
secured, as well as the wedge and the security pin of the quick release hitch system.
•Ensures that the hoses have the correct length and are at no risk of interfering with
any of the moving parts. Also make sure they cannot wear or damage because of
contact with the grab or material that is moved by the grab.
Procedures to follow before initial use

Daily Maintenance
1 = Attention: fix nut with the conical side to the inside
2 = Bolts need to be tightened with a torque as shown in the table (see page 15)
To ensure the wear blades are securely fastened to the shell it is recommended to place
some additional spot welding between knives and shell base.
For maintenance work, always place the grab in open position on a flat and stable surface
and ensure the excavator cannot move.
During maintenance on the hydraulic system the hydraulic hoses need to be
disconnected. Before disconnecting ensure there is no pressure on the hoses. Consult
the manual for the excavator.
The grab must be lubricated once every 8 operating hours with the same lubricant
recommended for the excavator. For the position of the grease nipples and frequency of
lubrication, see the schedule on page 9.
When the cutting blades of the grab shells are worn down to such a degree that the grab
can no longer close fully, all work should be suspended immediately and the
exchangeable wear blades must be changed or replaced (Note that the wear blades also
function as final stop of the cylinder—neglect or excessive wear can lead to damage).
