Product InformatIon

SSX45E All electric Ship to Shore Spreader

The Bromma SSX45E all electric ship to shore spreader

has been designed and built for long, reliable service on

latest generation ship to shore cranes in high throughput

environments.

The telescopic spreader is of a 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 spreader can adjust its length to

lift 20 foot, 30 foot (option), 40 and 45 foot containers

using ISO floating twistlocks.

The spreader can retract to the 19 foot–6 inch position

in case it becomes jammed in the ship’s 20 foot cell.

The design with recessed end beams makes handling of

lashing frames and hatch covers possible. All motions of

the spreader are controlled from the driver’s 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 SSX45E are electrically driven. This

means that the speader is silent and consumes energy only

when moving.

Made of high quality steel, the standard SSX45E 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 assemb-

led, adjusted, removed and are accessible for inspection and

maintenance.

The spreader comes with the SCS3 Spreader Control System,

reducing and preventing downtime through improvements

in the area of electrical connections. It will also shorten

downtime through faster spreader fault diagnostics.

telescoPIng system

Glide plates

The two telescopic beam units run on glide plates, one at each bottom corner of the main frame and one at each top end of the telescopic beams. Glide plates are also mounted at each lower end of the telescopic beams. This ensures low friction and a smooth movement when telescoping.

telescoPIc drIve system

The telescopic system is driven by means of an electric motor with gearbox connected to an endless chain. The motor is equipped with a built in brake which holds the spreader in position during operation. The chain is fitted 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 imposed to the spreader ends.

The telescoping system’s 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 flexibility in the system allows small changes in spreader length when handling distorted containers.

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 con-trolled by an absolute encoder placed on one of the gear-boxes.



twIstlock system

flIPPers

The spreader is equipped with flipper units located in each corner of the spreader to guide the spreader onto the con-tainer.

The flipper unit consists of an electric motor attached to a gearbox. The gearbox is bolted to the end beam. The flipper arm is attached to the outcoming gearbox shafts. The flipper arms make a movement of 180 degrees from their upper position down to their working location. The gearbox is equipped with a safety function which makes the flipper retract at a force of 3,000 Nm or more.

Blocking key

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 positions. 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 passes underneath it. During hoisting the land-ing pin is in the ”down” position and prevents the twistlock from turning. The floating range is ±6 mm in all directions. The twistlock pins are proof load tested to 37 tonnes.



electrIcal system

The power required to operate the spreader’s electrical components is obtained from the crane. All electrical com-ponents on the spreader are designed to withstand loads imposed 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 controls have a hoist permit safety circuit.)

Spreader twistlocks can only be ”Locked” or ”Unlocked” when all four corners are properly seated on a container or hatch cover.

monItorIng and dIagnostIc system scs3

For monitoring and diagnosing the SSX45E is equipped with the SCS3 Spreader Control System. The SCS3 can con-nect to a wide variety of host controllers including PLCs and PC-based control systems.

The rugged SCS3 control 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 SCS3 system delivers advanced monitoring and diag-nostic information, which means that service staff can react faster to fault events. Instead of investigating possible sources of fault events one by one, the SCS3 gives service technicians specific, precise information, enabling them to quickly solve the problems occurred.

The SCS3 system simplifies 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.

The SCS3 system comes as standard with all Bromma All electric ship to shore systems.
