®Applications and Examples

Brauer Ltd manufactured according tothe design specification of J Murphyand Sons Limited, Gas pipe tunneltrollies for the gas ring mainimprovement to the west of Londonfrom Harefield to Southall for theNational Grid.

The gas pipe is required to bepush/pulled into position andstatically supported whilst empty(565kg/m), until the tunnel annulus isfilled, the trollies must also supportthe pipe when filled with water tosupport hydro testing (1735kg/m)

The 4 sections of the tunnel havelengths of 974m, 756m, 505m and207m respectively and the totalimprovement section is 27 kilometres

The bored tunnel of concrete sectionwas 2.2m diameter and the gas pipewithin this tunnel was 1.2m diameterleaving very limited space betweenthe two, so the gas pipe supportingtrollies had to be small enough toenter this gap between the pipe andthe tunnels walls but have very highloading capacity to take the gas pipeas it was pulled/pushed into the outertunnel. The rail system for the trollieswas laid on a bed of silicon sand.

Brauer Ltd provided a total solution of88 low height / high load capacitytrollies which ranged from 10,000Kgeach to 22,000Kg each.

A ship lift and transfer dock system forremoving ships from the sea and thentransferring ships around the dock for repairand maintenance to take place. Three sizes ofwheels are used througout the dock.

Rated LoadSDF 450/95/TBM75FH + AXLE 25500 Kg

SDF 350/85/TBM75FH + AXLE 19500 Kg

SDF 250/80/TBM50FH + AXLE 13000 Kg

FH = Flame Hardened

The SDF 250 and 350 being primarily used onthe ship lift trolley with the SDF 450 mainly onthe transfer system. The wheels have beensimplified and redesigned to ensure longer life,easier installation and lower maintenance.

Multi-pivoting, dual purpose castor with directionalswivel top plate. Fitted with 4 steel double flange railwheels, 450mm tread diameter and 90mm tread widthand 8 anti-hydrolysis polyurethane tyred wheels,505mm tread diameter and 150mm tread width.All axles are ground stainless steel running in selflubricating nylon bushes.

Load Ratinga) When mounted on rail and running on the double

flange wheels – 160 tonne per castor assembly.b) When running on polyurethane tyred wheels – 76.8

tonne per castor assembly.

Wheel and axle assemblies used in a rotating drumapplication. Given the extreme conditions and highloadings involved the wheels and axles have beenspecifically designed to the customers requirements thatdemand flat tread wheels with axles that are capable oftaking a load in excess of 75 tonnes.

The wheels shown are SFT600/250/KM150 with an axleØ150mm reducing to 100mm for the bearing housing.

These special 28tonne and 42tonne pivot castorswere designed to be used on 115 tonne capacityelectro-mechanically controlled Portal Stands

The portal stands are used inthe support of the wire tensioncable as part of a steel ropemanufacturing process.

The machines to carry out this process weremanufactured in England and then exported to theSteel Wire Rope and Tension Cable Manufacturingcompany in Scandinavia.
