Location: Serangoon North, block 106
Company: Tong Soon Crane
Machine: TADANO TG-3600M, maximum capacity 360 tons at 3 metres radius with 17x2 lines and dual hooks.
Status: Second (or more) ownership. No LTA registration. LM60121E.
Project: Lift upgrading, crane lifting steel frames for lift shaft.
Setup: 85 tons counterweight. 32.6 metres of main boom and 35 (or 47?) metres of lattice luffing jib.
Hook placement: Load hook maximum 10 tons, 1 line.
What is so special: This is the largest Japanese made mobile crane in Singapore, the only unit of such model here, largest mobile crane made by Tadano Japan (not counting overseas models like AR series) and second largest mobile crane made in Japan, the largest being Kato NK5000, 500 ton mobile crane. With so many 'only', this is a crane not to be missed!

This crane has six axles and conforming to Singapore/Commonwealth/European laws/rules that each axle do not exceed 12 tons, it would be about 72 tons when underway.

The load of the vehicle. The maximum lifting weight is already specified by the specifications above.

Axle has something called axle load, means each axle can only carry that amount of weight, for the safety of the vehicle and prevent damage to road surfaces.

According to local laws, the maximum weight that an axle can carry for trucks, which include cranes, is 12 tons. This too applies to trailers and other special equipment. The number of axles is definitely not increased to look good/macho/impress men and women.

Hence when deducing vehicle weights, the direct thing to look for is axles. For tractors, with two axles their weight would be around 10 tons, plus another axle for carrying weight. The load that they haul is not factored into the axle issue.

If I have a three axle V6 Mitsubishi tractor, I can only carry 20-24 tons on the tractor (as ballast weight to prevent wheel slippage, a common sight in Europe but slightly rare in Sg) and haul maybe 100 tons of materials on a (100/12) 9 axle trailer (those trailers with smaller wheels follow the same rule). That is if the tractor is powerful enough, for 100 tons usually take 380-460 hp nominal for power.

This is usually how the equation work out. Power is seldom governed but as long as the vehicle will not pose a hazard to other road users in terms of rolling back on slopes, unable to go up slopes etc it would be okay.

Higher the power of the vehicle, the more axles it would need to power, at the same time, distribute the higher vehicle weight. As engine power and capacity goes up, weight of the engine goes up, and power axle increases weight in some cases. Take the Mercedes Actros 4860, it has a maximum load of 48 tons, 4 axles and 600 hp. The Mercedes SK 3553, 35 tons maximum, 3 axles and 530 hp.
