2.1.1 Name Plate Location
LAARMANN warrants that upon payment in full for any spare parts, it shall give good title of the goods to the Customer and
that the goods shall be free from defects of material and workmanship.
2.2 Characteristics of the Machine
LAARMANN manufactures a range of Crushers to suit most applications.
The basic concept of the LMFC 250 Jaw Crusher comprises a fixed jaw plate adjacent to a moving jaw plate, in a V configura-
tion, narrowing to an adjustable gap between the bottom edges of the two plates. The moving plate oscillates back and forth,
driven by an eccentric pitman shaft, powered by V belts from a standard electric motor.
The sample material is fed into the large top opening of the jaw plates via a vibratory feeder and is crushed by the oscillating
jaw plate as it passes through the narrow gap at the bottom, into a rotary sample divider. For an overview of the key compo-
nent parts, please refer to Section 5.3 Machine Data, of this manual. For hold down bolt locations, please refer to the General
Arrangement Drawing in Section 2.4 and for required site services please refer to Section 4.2, in the Installation Section of this
manual.

Minimum PPE used in this section
3.1 General safety rules
Only trained operators of forklifts or cranes are to lift or move the crated or un-crated LMFC 250 Crusher.
3.2 Storage, Transportation and Handling
The sections below outline steps and procedures for the transportation, handling and unpacking of the LMFC 250 Crusher
and storage of the machine if required.
3.2.1 Storage
If the machine needs to be stored for any reason, it should be indoors or undercover away from the effects of the weather.
3.2.2 Transportation
The packing crate has a pallet base for ease of access and movement with a forklift. The forklift must have a rated capacity
to lift the crated machine.
Please note, under no circumstances are slings or chains to be used to lift the crated machine. Always lift the machine
utilizing the recesses in the pallet base with a forklift.

3.3 Unpacking
3.3.1 Packing details
The LMFC 250 Crusher packing crate is manufactured to ISPM15 International Standard. Depending on the destination, the
crate may be an open slat type or solid sided. For dispatch from the factory the machine is strapped and bolted to the base of
the crate, black poly wrapping is used to protect the machine and the body of the crate is then screwed into position.
Note: The crate must be dismantled, a panel at a time, from the crate pallet base to unpack the machine. Do not lift the upper
crate from the machine as this may cause damage to the machine. The Figure below illustrates a typical open slat type of
crate.
