Spierings Crane Service Repair Manual

Spierings Kranen BV is a Dutch company founded in 1987.

Its specialty is truck-mounted tower cranes, which have become popular due to their mobility and quick set-up, which usually takes just 15 minutes.

These cranes are particularly useful in urban areas, where this type of crane can lift loads and carry them over buildings more easily than conventional telescopic cranes. Spierings cranes can be found in Europe and Canada, and the company continues to expand.

The SK599 AT5 is a 60-tonne, five-bridge crane with a rated lifting capacity of 9 tonnes and 1.9 tonnes at the boom end, with a reach of 50 metres. It can lift loads to a height of 32.6 m, and when the boom is tilted at 30 degrees, to a height of 56.3 m. This model was released in honor of the twentieth anniversary of the Spierings company, and this is the first Spierings crane.

The model is supplied in a regular box with images, which contains two foam rubber trays, carefully protecting the model from damage.

Some collectors note that the car itself is mounted on wheels slightly higher than necessary.

At the front of the driver's cabin there are headlights with lenses, regular windshield wipers and rear-view mirrors, as well as the aforementioned signal orange lights, which are installed on the roof. The interior of the cabin is carefully reproduced, you can see the steering wheel, pedals, seats. Behind the cabin is the engine compartment, it has high-quality grille parts made using photo etching.

The cargo platform has a textured anti-slip surface. Under it are all-metal outriggers and stands, with warning signs applied to them. Some excellent rubber mudguards protect the outriggers, with the Spierings logo printed on them.

There is a storage area at the rear, containing four metal plates that fit under the outriggers, a very nice touch. The model has a drop-down grille, and two orange beacons and painted light clusters complete the picture.

The crane sits on a large, clearly visible slewing ring. It is very detailed, with tiny lettering and signs that look authentic. Many of the small mechanical parts are modelled very accurately. The engine bay of the crane shows the engine, cables and exhaust system. The model comes with a separate counterweight block, which can be attached when the boom is raised to help keep the model balanced.

The boom is three-stage and telescopic, and is made entirely of metal parts, with the exception of the bearing at the top of the second section. The casting is very good, with a lot of structural detail. A three-section telescopic ladder is attached to the boom, along with a lift that has small warning signs.

On top of the boom is the driver's cabin, a well-modeled part, with windshield wipers and a carefully executed interior of the cabin, including an electrical cabinet.

On the floor of the cabin is a grate, which also acts as an entrance hatch, although you cannot see through it, as you can through the grate in a real car. Also on the top of the boom are orange flashing beacons and headlights.

The mechanical couplings of the crane are almost entirely metal, the only exception being the cylinder covers of the boom tilt mechanism, which are made of plastic. The boom compartments are triangulated, metal, each of the four boom sections is made of two cast parts - the two upper sides are one part, and the lower one is the other.

The workmanship is very high, so the boom looks convincing. There are several headlights on the boom, each of them has a tiny bulb. The trolley is made of metal, as is the hook block, and they both have working pulleys.
