Kalmar wins<br />

Nelcon refurb<br />

contract<br />

Following the contract to maintain<br />

Finnsteve’s straddle carriers, FLTs and terminal<br />

tractors in Kotka, Kalmar has secured<br />

a refurbishment deal from the Port<br />

of Tilbury to upgrade 13 of its straddle<br />

carriers. However, in this case, Kalmar will<br />

effectively be refurbishing third party<br />

machines as the contract relates to Nelcon<br />

diesel-electric machines delivered before<br />

Kalmar acquired Nelcon and no longer<br />

manufactured by Kalmar, having been replaced<br />

by its E-Drive designs.<br />

The machines have been assessed individually<br />

and major repairs identified,<br />

prioritised and programmed according to<br />

the actual requirements. This process,<br />

Kalmar considers, provides better value<br />

for money than simply renovating each<br />

machine according to set guidelines.<br />

Michael Quinn, terminal engineer at<br />

TCS, states: “Our Nelcon machines are<br />

now around 10 years old and we want<br />

them to last 15 years. It had become obvious<br />

that without major refurbishment,<br />

reliability would become a real problem.<br />

Initially, we planned to do the work ourselves<br />

and costed the project on this basis.<br />

However, in talks with Kalmar, it became<br />

clear that their people could do the work<br />

within our budget, leaving our team to<br />

focus on cranes and breakdowns.”<br />

Each of the straddle carriers had covered<br />

around 20,000h, so overhaul of the<br />

Volvo Penta engines was the first priority,<br />

to give a further operating 10,000h.<br />

As they are constant speed engines driving<br />

a generator, this is achievable. TCS<br />

had also identified increasing reliability<br />

problems with the steering and braking<br />

systems and so these were renovated, as<br />

were the electrical drive systems, including<br />

the ac invertors.<br />

● Kalmar has established its own subsidiary<br />

company in South Africa for sales of<br />

straddle carriers and RTGs. Kalmar Industries<br />

South Africa (Pty) Ltd, located<br />

in Durban, will manage ongoing deliveries<br />

of straddle carriers as well as the new<br />

RTGs that Kalmar is believed to have on<br />

order from SAPO (last month’s<br />

<strong>WorldCargo</strong> <strong>News</strong>, p4). African National<br />

Engineering continues as Kalmar’s service<br />

partner for straddle carriers and RTGs.<br />

Kalmar reach stackers and lift trucks will<br />

continue to be sold through Saficon.<br />

●The Port Authority of Jamaica (PAJ) has<br />

ordered 24 4-high Kalmar CSC 450 straddle<br />

carriers and six 7-high Kalmar ECH<br />

mast trucks for its Kingston facility. New<br />

business secured last October will boost<br />

throughput by some 500,000 TEU/year<br />

and push the terminal through its 1.5M<br />

TEU/year theoretical capacity. Because<br />

land expansion is not feasible in a short<br />

time frame, PAJ decided that the best solution<br />

would be additional stacking density.<br />

As well as a notional 50% capacity<br />

gain in the CY from 2- to 3-high, the 7-<br />

high ECHs will clear an additional footprint<br />

for loaded containers.<br />

The first units are to be handed over<br />

this month, with delivery completion<br />

scheduled for July.The order will bring<br />

the total number of straddle carriers in<br />

operation at Kingston to 74.The price of<br />

the CSC450s has not been disclosed although<br />

a statement from Cargotec says<br />

that “unit prices for straddle carriers vary<br />

between €700,000 and €900,000.<br />

Kingston will continue to use 1 over 2 machines<br />

under the cranes because of limited clear heights<br />

Liebherr-Werk Nenzing (LWN) is introducing<br />

individual wheel drive to its LRS<br />

645 reach stacker with hydrostatic transmission,<br />

introduced in 2004. Independent<br />

wheel drive is a standard feature of<br />

LWN’s harbour mobile cranes.The development<br />

on the LRS645, says the company,<br />

“offers outstanding opportunities such as<br />

minimising side forces on the steer wheels<br />

and more effective driving gear.”<br />

The first machine with the new drive<br />

is being delivered to Howland Hook<br />

Marine Terminal in NY/NJ, already a<br />

customer of Liebherr Container Cranes.<br />

The basic principle of hydrostatic<br />

transmission is its high power density that<br />

means small dimensions of components<br />

as well as small induced masses.This gives<br />

the reach stacker fast acceleration and a<br />

high efficiency factor and all acceleration/<br />

Reach stacker “revolution”<br />

deceleration is entirely stepless.This has a<br />

positive impact on the lifetime of various<br />

components and adds to driver comfort<br />

Conventional designs also induce<br />

high tyre wear on the steer axle and the<br />

axle support limits the degree of turn<br />

anyway. Liebherr is now fitting individual<br />

wheel hubs with integrated planetary<br />

gears and hydrostatic drives for the driven<br />

wheels. Every driving wheel or every pair<br />

of wheels can be controlled individually.<br />

It is thereby possible to supply different<br />

drive powers to the individual wheels<br />

The power of innovation.<br />

The visionary new Reachstacker from Linde.<br />

With its outstanding agility, superb precision and smooth control the new Reachstacker from Linde<br />

embodies all the finest qualities of refined power.<br />

Much more than just the sum of its parts, here is Man and machine in harmonious action. The fully<br />

integrated, versatile and responsive control and operating system is a visionary concept designed to<br />

make life easier. Combine this with Linde’s truly global service, spares and technical back-up and you<br />

can understand why we are world leaders.<br />

The visionary new Reachstacker from Linde: the next generation of working solutions delivering<br />

greater productivity and efficiency.<br />

and a strong torque can be built up that<br />

supports the steering movement and the<br />

stability of the reach stacker. Lateral forces<br />

at the steer wheels are reduced almost<br />

completely. Other claimed advantages are<br />

reduced strain on the steer wheels and<br />

better running performance. Traction is<br />

increased on slippery surfaces as the<br />

wheels can be individually supplied with<br />

more driving torque depending on the<br />

traction present. Even anti-slip control for<br />

each individual wheel is possible.<br />

There is no time delay when steering and<br />

the greater stability and reduction in “wobbling”<br />

can help with productivity. Fuel and<br />

gear oil consumption are also lower.<br />
