A Tradition of Innovation Product Information SSX45E All electric Ship to Shore Spreader 20 30 40 45 Container sizes with SSX45E 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 construction 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 foot 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 The spreader shown is customized with extra equipment 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 H 2 B 4. All components can be easily assembled, adjusted, removed and are accessible for inspection and maintenance. The spreader comes with the SCS 3 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. Major Features Adjustable for 20, 30 (option), 40 and 45 containers Recessed end beams allow handling of lashing frames and hatch covers Environmental friendly due to its all electric design Advanced communications system reduces downtime considerably Fast trouble shooting Fulfils design criteria among DIN 15018 H 2 B 4, FEM
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 Shock absorber Tension rod Tension rod Shock absorber Endless chain Electric motor/gearbox Absolute encoder 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 conditions. 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 controlled by an absolute encoder placed on one of the gearboxes. 2
Twistlock System Helical-worm geared motor Proximity switch for locked position Proximity switch for unlocked position Draw bars 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 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 landing pin is in the down position and prevents the twistlock from turning. Twistlock arm Proximity switch for landing pin Twistlock Blocking key Blocking stop Landing pin Flippers The spreader is equipped with flipper units located in each corner of the spreader to guide the spreader onto the container. The flipper unit consists of an electic 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. Flipper arm Electric motor Gearbox 3
Electrical System Monitoring and Diagnostic System SCS 3 The power required to operate the spreader s electrical components is obtained from the crane. All electrical components on the spreader are designed to withstand loads imposed during container handling operations and suitable for a marine environment. 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. For monitoring and diagnosing the SSX45E is equipped with the SCS 3 Spreader Control System. The SCS 3 can connect to a wide variety of host controllers including PLCs and PC-based control systems. CANopen box The electrical components are mounted in a stainless steel cabinet, IP66. All cables are well protected in cable chains. 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. The rugged SCS 3 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 different ways; on the screen, on the crane, via an external PC or a handheld computer. The SCS 3 system delivers advanced monitoring and diagnostic information, which means that service staff can react faster to fault events. Instead of investigating possible sources of fault events one by one, the SCS 3 gives service technicians specific, precise information, enabling them to quickly solve the problems occurred. The SCS 3 system simplifies handling of the spreader and prevents fault events. It also eliminates or minimizes junction boxes, terminal strips, and relays areas where wire breakage is common. Conventional wiring is reduced. The SCS 3 system comes as standard with all Bromma All electric ship to shore systems. 4
