Figure 1 - Explanation of design features

Table 1 - Technical data

●The unit should only ever be opened by a qualified specialist technician!

● The device must be protected from heat and moisture!

Before installation

● The crane scale is suitable for weighing and transportating accordance with EN 13155:2009-08

„Crane safety - section 5.1.1.1 Mechanical load-bearing parts“.

● The crane scale is attached to the hook of a crane in accordance with the regulations.

● The operator is responsible for the safety of the device. Crane scales are load suspension devices

according to DIN EN 13155, including accessories such as hooks, shackles and eyes. These parts must

be inspected for safety at regular intervals, but after one year at the latest. Visual inspections for

damage to tensile stressed parts such as hooks, eyes, connecting links etc. should be carried out

continuously.

Especially in 3-shift operation, this inspection cycle must be carried out in accordance with the

Industrial Safety Regulation §11.

We recommend a safety inspection every 4 months, and after 12 months at the latest an additional

crack detection with the electrical crack detection method or the red-white process must be carried

out during this monitoring.

We would be pleased to take over these safety checks for you by sending your device to our head

office (EHP Wägetechnik GmbH | Dieselstraße 8 | 77815 Bühl).

● Check that the safety flaps of the hooks are in perfect condition. These prevent hanging loads

(ropes, chains, etc.) from unhooking.

● Check that the eyelets, shackles, lower load hooks, bolts and safety pins are in perfect condition.

In case of heavy wear (≥10% of the original dimensions) of these parts, please contact the EHP

customer service.

● Safety and protective devices must never be removed or modified.

● Make sure that the scale is securely suspended.

● Observe the regulations for prevention of accidents.

● Keep this technical manual in a safe place close to your working area.

When moving loads, avoid at all costs:

●Lifting unevenly.

●Trailing the goods on the floor.

●Sudden lifting or setting down or abrupt stopping.

During use:

● Staying under lifted loads is strictly prohibited!

● Always ensure that the scale and load are securely hung up.

● Lifting or transporting persons and live animals with the crane scale is prohibited!

● Loads that are heavier than indicated on the load plate mounted on the side of the crane scale

are not allowed to be lifted.

●When lifting the load, move away a few meters and check that the load is correctly balanced by

lifting the load a few centimeters from the ground. On the display of the crane scale you can read if

the load is exceeded..

● If the display starts flashing or the display shows OL, the maximum load has been exceeded. The

load must be lowered again immediately.

● Never allow the load to swing.

● Lift at minimum speed.

For CE-M approved scales (model KGY):

● CE-M approved scales are only approved for use in a weatherproof environment.

● Do not operate the scale at risk of frost (below -10°C) or in a very hot environment (above +40°C).

In this temperature range.

● The verification marks and seals on CE-M approved scales must be handled with care. If they are

damaged, please notify your regional weight and measures authorities.

In case of malfunctions:

●Repairs may only be carried out by qualified personnel!

●Read the chapter "Troubleshooting“ and „Error detection“.

●Contact the EHP customer service.

Special applications:

A standard crane scale cannot be used in pickling or galvanizing baths within production, as this can

lead to irreversible damage to the load-bearing parts and electronics due to liquid metal

embrittlement. If you still wish to use the crane scale in these areas, it must be specially equipped

by EHP. Even if the crane scale is well-protected, damage can still occur from this application.

Technical defects caused by use in these baths are not covered by warranty or liability.

The warranty is void in case of:

•Improper use of the manufacturer's instructions in this technical manual.

•Operating the device in an unintended use.

•Mechanical damage, damage by humidity and liquids.

•Mechanical modification of the crane scale.

•Wear and tear.

•Use of non original EHP batteries, chargers and power supplies.

•Manipulation of the loading device.

•Overloading the crane scale.

•Modification or replacement of the load-bearing parts.

● Digital crane scale KGW | KGW-Y | KGY

For extreme foundry applications, shock and

heat protected

For permanent industrial use

(KGW-Y=calibrated; KGY=CE-M approved)

Figure 3 - Front view

The LED-Display (1) is located at the front of the crane scale. The control panel with 6 functional keys

is covered and protected by a protection cover (2).

The bracket or eyelet (3) is located on top of the crane scale and the load hook (4) is located at the

bottom. The KGW model is also protected from extreme temperatures by a surrounding heat shield

(5). Depending on customer configuration, the figure shown above may vary.
