PRODUCT INFORMATION
OSR45 HIGHLIGHTS
Telescopic (20 to 45 foot) overheight frame for highest flexibility
Fast and safe container handling, low maintenance
Robost, fully mechanical design with no power supply or hydraulics
Easy to transport as it fits into a 20 foot container
Bromma ISO floating twistlocks
Index unit eliminates slack in twistlock system
The OSR45 is an automatic telescopic overheight frame. It can be used together with Bromma spreaders, and also other spreader brands. Using the OSR45 increases the operational speed and safety of cranes, reachstackers and straddle carriers when handling flats and overheight containers.
The OSR45 can be attached under any parent spreader with ISO standard base measure which is equipped with Bromma overheight frame lifting lugs (can be ordered separately).
The cargo is lifted by the spreader twistlocks which act as extended legs to the spreader. This results in a much faster and safer handling of goods, compared to using chains.
As the spreader telescopes, the overheight frame telescopes simultaneously, allowing the unit to handle 20, 30, 40 and 45 foot containers with overheight cargo.
OSR45 LOAD COMBINATIONS
OSR45The exact load combination would depend on the design of the parent spreader.
The OSR45 is only mechanically operated and does not require any power supply or hydraulics for attaching itself to the spreader, nor for its operations.
The OSR45 is as standard delivered in a demounted form in a 20 foot container for easy on-site mounting, thus reducing transportation costs. It can also be delivered as an option in a fully assembled form, but will then need to be delivered on a flatrack.
The OSR45 frame can be quickly and automatically connected and disconnected to the storage fixture. The fixture can be placed on the ground or attached to the crane legs. It can also be moved using the storage fixture or a forklift.
The exact load combination will depend on the design of the parent spreader.

Steel structure of OSR45
OSR45 STRUCTURE
Made of high quality steel, the OSR45 provides high lifting capacity with a low nominal tare weight.
All components can be easily assembled, adjusted, removed and are accessible for inspection and main-tenance.
The overheight frame is designed in accordance with EN13001.
The OSR45 is available in different colours but will be delivered in RAL2004 (orange) as standard, unless specified otherwise.
The OSR45 has two short side profiles and one tele-scopic 20 to 45 foot beam that are bolted together.
The telescoping runs on glide plates and follows the parent spreader telescoping. The overheight frame can be connected to any parent spreader with ISO stan-dard base measures, independent of twistlock rotation directions. The spreader must be equipped with Brom-ma overheight frame lifting lugs (can be ordered sep-arately).
The OSR45 comes as standard with a storage fixture. During storage of the OSR45, the overheight frame will be stored in the storage fixture, which can be placed on the ground or mounted on the crane legs.

OSR45 - CONNECTING THE OSR45 TO A SPREADER
To pick up the overheight frame from the storage fixture the spreader needs to land on the overheight frame and then do the twistlock lock plus unlock motion.
During this twistlock movement, a cam wheel in the storage fixture will rotate to release a mecha-nism which has been holding up a push rod in the overheight frame. The push rod is connected with a spring mechanism, which will push it downwards, and as a result pull up the latches to engage on the spreader lugs.
When the push rod comes into a down position, a plunger will protrude into a hole in the frame, ensur-ing the latch will stay in its hooked-on position.
The push rod gets an extra movement downward through a connected spring mechanism, and will be kept in position.
As the twistlocks will now be unlocked, and the latches engaged on the spreader lugs, the overheight frame can be lifted from the storage fixture. The overheight frame will now only be hanging through the latches holding on to the spreader lugs.
Once the overheight frame is lifted up from the storage fixture, a spring mechanism will push up the release mechanism in the storage fixture, for it to function accordingly when the overheight frame needs to be disconnected from the spreader.

OSR45 - DISCONNECTING THE OSR45 FROM A SPREADER
When the operation with the OSR45 is completed, the overheight frame needs to be put back on the storage fixture in order to be disconnected from the spreader.
The release mechanism in the storage fixture will press the push rods on the overheight frame upwards after landing the overheight frame on the storage fixture. A wedge connected to the push rod will re-lease the plunger, ensuring the push rod can be fully moved upwards, unlocking the latches.
This will release the overheight frame from the spreader, and the spreader can move away and oper-ate on its own.

Twistlock connection system

The overheight frame twistlocks act as extensions of the parent spreader twistlocks. Both spreader and overheight frame twistlocks unlock and lock simulta-neously.
Each twistlock incorporates a landing pin with a mechanical interlock to prohibit unlock operations when under load, similar to the Bromma spreaders. The twistlock pins are proof load tested to 40 metric tons.
An index unit makes the overheight frame twistlock move fully 90 when unlocking or locking, eliminat-ing any slack in the twistlock system.
TWISTLOCKS
The overheight frame twistlocks act as extensions of the spreader twistlocks and will work in the same way as a normal spreader operation.
When the twistlocks from the overheight frame are in locked position, the overheight frame will be held in the spreader by the twistlocks.
The latches will still be locked, but there will be a clearance between the latches and the lugs, so the full weight of both overheight frame and load under-neath will hang on the twistlocks instead of the lugs and latches.
As a result, the spreader lugs will only be under load when the twistlocks are unlocked, and there is no load hanging under the overheight frame.

OSR45 - STORAGE FIXTURE TRANSPORTATION
The storage fixture can be lifted by the spreader to-gether with the overheight frame with the twistlocks in locked position. It can also be transported by a fork lift truck or locked to a trailer.
