Job Report

Situation

Saqr Port is located at the northern tip of the United Arab Emirates,

with access to the Arabian Gulf, and is the Middle East’s major

port for bulk cargoes, aggregates, pipes, cement, coal and other

raw materials imported for the local industries. With its unique

geographic position and superior intermodal connections, Saqr

Port is also well-known for highly efﬁcient material handling and

premium infrastructure. The port’s expertise has attracted additi-

onal business which has led to increased cargo volumes, over the

past 5 years.

Task

Saqr Port handles several materials with densities up to 2 t/m³

and loads on average around 5 ships per day. The most common

material is limestone, which is characterized by small rocks, and

when the grab is closed, some of these rocks are compressed

which results in intense shaking and stress for the crane structure,

due to strong dynamic forces. Thus, in order to minimize forces

acting on the crane structure a smaller grab (22m³) was used which

naturally reduces turnover.

Solution

Saqr Port decided to install SmartGrip on their newest mobile

harbour crane, type LHM 550, to cope better with limestone. This

innovative system optimises grab ﬁlling rates in a self-learning

process which results in more turnover, zero overloads and less

stress for crane and operator. For the new LHM 550, the Smart-

Grip parameters (e.g. closing speed, slack rope values) have been

speciﬁcally adapted for the rocky limestone material.

Performance

Thanks to the installation of SmartGrip, Saqr Port has been able

to use the bigger grab (32m³) without additional stress for the

crane structure and the average limestone load has increased by

more than 30%, leading to signiﬁcantly more turnover. It also has

additional beneﬁts, time-consuming overloads have been comple-

tely eliminated and due to very smooth force effects, shaking

has dramatically decreased, leading to more driver comfort and

extended life span of the crane.

„Installed in our new LHM 550, the innovative SmartGrip system provides valuable advantages. The system

optimises our grab operation and with zero overloads, it increases our turnover plus saves our crane struc-

ture, leading to longer life span of our equipment.“ Mr Philip Madin, Operations Manager Saqr Port
