| The Wolff 7532 tower crane is a large trolley jib crane of conventional design and features a jib length which provides a reach of up to 75m at which point it can lift 2.9 tonnes. At 30m radius it can lift 12 tonnes.
This model comes with a jib that scales at the maximum 75m of the real crane.
Packaging
As with other Ros tower crane models it comes in a very large box and is largely pre-assembled and fully reeved. Both the mast and the entire crane above the slewing ring are fully made up and just need to be joined together, which takes only a few minutes.
A CD is included and this has simple assembly instructions but unfortunately it does not include any photos or specifications of the real machine. The review model had no defects or missing parts.
Detail
The mast is a shared design with other Wolff tower crane models. At the bottom, the cruciform arrangement screws onto a black plastic base which provides additional stability. Plastic access ladders run up through the mast, and there are access platforms within each mast section. The mast appears to be made up of separate sections, but these are glued together so it is not easy to build the crane to any height other than the prefabricated one. Large solid blocks provide ballast at the bottom of the mast and these are cast and painted to resemble concrete slabs. A capacity board is fitted just above the base. Four floodlights are provided and these can be fitted as desired.
A climbing frame is included and this is a large piece with the main structure in metal. The access platforms are plastic and they appear a little too narrow on the model. More surprisingly, the climbing frame has complete lattice work where the mast section should be able to be installed through the frame which seems an odd aspect of the model. The hydraulic jack is not modelled and there is no connection point on the mast for the top of the climbing frame.
The jib is well made and straight, which is a very good achievement given its length. It is made up of seven separate sections but unfortunately these are riveted together so it is a pity that alternative shorter jib configurations cannot be easily built. An experienced collector could drill out the rivets and replace them with pins to provide a more flexible model.
Small brass pulleys are used to run the trolley and hoist ropes. A warning light is modelled at the end of the jib and there is a mesh walkway that runs to the end of the jib. A Wolff signboard clips into the jib latticework.
The counter jib has a convincing structure with a full mesh walkway, and the counterweights look like concrete slabs. However, the handrails are a little large for the scale. The cab and equipment box is plastic, but the detail is reasonable with a windscreen wiper and operator's seat.
The trolley is metal with brass pulleys, as is the hook, and both are well made. A Wolff 'medal' is provided which can be used as a load for the crane.
Features
The hook can be raised and lowered using the winch and there was enough friction on the review model to be able to hold a load.
The crane can rotate fully and smoothly, and is reasonably stable throughout, although not much load can be a carried at the end of the jib.
It has a working trolley which moves by turning the winch on the trolley motor. It works reasonably well although it gets stiff at various points due to the reeving on the drums.
Quality
The casting and paint work on the model are good, and the colour match of plastic parts is very good.
Price
The model is reasonably priced overall given its relatively large size.
Overall
As with other Ros models of Wolff tower cranes the model looks very good and is a convincing representation of the real crane. Some of the details and accuracy could certainly be improved however, and the model would have been improved by being able to be broken down into component parts like the original. The model is recommended to tower crane collectors.
