YTS45E Marathon All Electric Separating Twinlift Yard Crane Spreader

MAJORFEATURES

Two 20 containers can be moved apart from 0 to 1.6

metres (05) under full load

Environmental friendly due to its all electric design Advanced SCS3communications system reduces down-

time considerably

Fast trouble shooting

Fulfils the design criteria among DIN 15018 H2B4, FEM

1.001 and British Standard BS 2573

With the Bromma all electric adjustable twinlift Spreader YTS45E

a larger percentage of above-deck containers can be transported

in twinlift mode. The twinlift spreader can move two 20 foot

containers from a spacing of 0 to 1.6 metres (0 to 5 foot) under

full load while suspended under the twistlocks.

Two containers can be moved synchronised towards one another

and apart from one another. The movements can be done at

anytime in the crane cycle and are mechanically controlled to be

symmetrical. There is no stopping time to change the container

spacing.

The telescopic spreader YTS45E is of rectangular frame construc-

tion enabling easy location on containers. The spreader is as

standard equipped with 4 x 10 tonnes lifting lugs in the corners

of the end beams for heavy lifts and for handling damaged

containers.

The design with recessed end beams makes handling of lashing

frames and hatch covers possible. All motions of the spreader are

controlled from the drivers cab and there are provisions made for

signals in the cab indicating the position of the twistlocks and

landing pin status.

All movements of the YTS45E are electrically driven. This means

that the speader is silent and consumes energy only when moving.

Made of high quality steel, the standard YTS45E spreader provides

high lifting capacity with a low nominal tare weight thanks to

the box design of the telescoping beams and the main frame.

The spreader is designed in accordance with DIN 15018 H2B4. All

components can be easily assembled, adjusted, removed and are

accessible for inspection and maintenance.

The spreader comes with the SCS3Spreader Control System,

reducing and preventing downtime through improvements in

the area of electrical connections. It will also shorten downtime

through faster spreader fault diagnostics.

The two telescopic beam units run on maintenance-free

roller bearings, one at each bottom corner of the main frame

and one at each top end of the telescopic beams. Glide

plates are mounted at each lower end of the telescopicbeams. This ensures low friction and a smooth movement

when telescoping.

This system stops accurately in all positions. It is durable and

strong but has low weight, is easy to maintain and has long

service intervals. The telescoping positions are controlled by

an absolute encoder placed on one of the gearboxes.

0 to 1.6 meters

Two 20 foot containers can be moved apart from 0 to 1.6

meters under full load. The movement can be done at any-

time in the crane cycle, which means there is no stopping

time to change the container spacing.

TELESCOPINGSYSTEM

TELESCOPICDRIVESYSTEM

The telescopic system is driven by means of two electric

motors with gearboxes connected to an endless chain. The

motors are equipped with a built in brake which holds the

spreader in position during operation. The chain is tted

with a Bromma design shock absorber at both ends. The

shock absorber is designed to dampen the effects of impact

on the spreader structure and components due to loads im-

posed to the spreader ends.

The telescoping systems ability of absorbing extreme loads

mechanically provides the end user with a highly reliable

spreader with increased life even under extreme load condi-

tions.

The exibility in the system allows small changes in

spreader length when handling distorted containers.

ADJUSTABLETWINLIFTSYSTEM

The main frame is tted with four retractable oating twist-

lock housings for handling two twenty foot containers si-

multaneously. The twinlift units move simultaneously in

pairs, keeping the distance to each end beam to separate or

retract two 20 foot containers between 0 and 1.6 meters.

The movement is achieved by an electric motor/gearbox

placed centrally on the main frame. The force is distributed

to each side by a shaft across the main frame. The shaft

TWINLIFTSYSTEM

is equipped with a chain wheel at each end.

These chain wheels drive an endless chain at

both sides, to which the twinlift units are at-

tached. The position of the twinlift boxes is con-

trolled by an absolute encoder placed on one of

the chain wheels.

The twinlift units run on both glide plates and

steel wheels.

The twinlift system is designed in such a way

that certain irregularities between the two 20 foot

containers are accepted as swown below.

Max. 6 cm

Max. 13 cm

Max. 1.5 cm when containers are lifted

TWINLIFTUNITS

The twistlock housing in each twinlift unit can be raised

and lowered by means of an electric motor on top of the

twinlift unit. The motor shaft passes through a guide plate

and is connected to an arm. The arm has a trunnion which is

connected to a damper. The lower end of the damper is con-

nected to the twistlock housing. The vertical movement of

the twistlock housing is guided by slots in the side plates of

the twinlift unit.

The twinlift twistlocks are maneuvred by a separate electric

motor, which is connected to the twistlock arm by a draw

bar. An analog switch indicates the locked and unlocked po-

sitions. The switch also ensures that the motor is stopped in

correct location at each end position.

A spring loaded landing pin near each twistlock is pushed

up into the twistlock housing when the spreader is landed

on the container. The twistlocks can only be turned when all

the corners of the spreader are landed. Twistlock

TWISTLOCKSYSTEM

GUIDEARMS

The spreader is equipped with four xed guide arms to

guide the spreader onto the container. These are located oneat each end of the long side of the spreader. The guide arms

are fastened by means of bolts and nuts on a slotted adaptor.

The bolts can be slided out of the slot if sheared off. Several

guide arm combinations are available.

Four twistlocks are located in the corners of the spreader to

engage and lift the container.

The twistlocks are manoeuvred by a helical-worm geared

motor, which is connected to the twistlock arms by two draw

bars. Two switches indicate the locked and unlocked posi-

tions. The switches also ensure that the motor is stopped in

correct location at each end position.

A spring loaded landing pin near each twistlock is pushed up

into the twistlock housing and activates a proximity switch

when the spreader is landed on the container. The twistlocks

can only be turned when all the corners of the spreader are

landed. At the same time, the blocking key is moved high

enough so the blocking stop on the twistlock lever arm pass-

es underneath it. During hoisting the landing pin is in the

down position and prevents the twistlock from turning.

ELECTRICALSYSTEM

The power required to operate the spreaders electrical

components is obtained from the crane. All electrical com-

ponents on the spreader are designed to withstand loads im-

posed during container handling operations and suitable for

a marine environment.

The electrical components are mounted in a stainless steel

cabinet, IP 67. All cables are well protected in cable chains.

The spreader is supplied with CANopen slave units. This

enhances the possibility of monitoring each I/O point and

reduces the number of cables needed and the replacement

time for connecting sensors and actuators to the controls.

CANopen box

The spreader has a control voltage of 24 V DC.

The electrical safety features to protect and ensure proper

handling of containers are as follows:

Spreader cannot be hoisted unless all four twistlocks are

fully Locked or Unlocked. (Provided the crane con-

trols have a hoist permit safety circuit.)

Spreader twistlocks can only be Locked or Un-

locked when all four corners are properly seated on a

container or hatch cover.

MONITORINGANDDIAGNOSTICSYSTEM

SCS3

For monitoring and diagnosing the YTS45E is equipped

with the SCS3Spreader Control System. The SCS3can con-

nect to a wide variety of host controllers including PLCs

and PC-based control systems.

The rugged SCS3control unit is a computer that is equipped

with a touch screen and mounted on the spreader for easy

access. Monitoring and diagnostics can be available in dif-

ferent ways; on the screen, on the crane, via an external PC

or a handheld computer.

The SCS3system delivers advanced monitoring and diag-

nostic information, which means that service staff can re-

act faster to fault events. Instead of investigating possible

sources of fault events one by one, the SCS3gives service

technicians specic, precise information, enabling them to

quickly solve the problems occurred.

The SCS3system simplies handling of the spreader and

prevents fault events. It also eliminates or minimizes junc-

tion boxes, terminal strips, and relays areas where wire

breakage is common. Conventional wiring is reduced.
