This model is a Schwing S 51 SX Concrete Pump mounted on a Mercedes-Benz Arocs 10x4 chassis. 

The maximum concrete output is 162m³ per hour and it has a vertical reach of 51m.

Packaging

The model comes in a Schwing branded box. 

There were no defects or missing parts on the review model.

There is no information about the real machine or the model.  Separate parts included are the hopper cover, a dozen spreader plates and and two black hoses.

Detail

Underneath, the chassis is fully detailed in metal with only the steering linkages being modelled for functionality rather than detail.  The tyres have a decent tread pattern which and the steering axles have wider tyres.

The cab has a see-through roof light and a distinctive Arocs grille.  There is a dummy number plate. 

Inside the cab, the seats have arm rests.

The front outriggers are metal with the unique curved Schwing design.  The rear outriggers are metal also.  The black pistons have visible screw threads, and the spreader plates are plastic.

The carrier body has a metal structure, with nice textured walking surfaces.  Wheel chocks are visible behind the protection bars between the axles.  The detailing of the pump is very good with hydraulic hoses adding to the look.

At the back there are lights and a number plate, and the bumper bar has colour highlights.. The hopper is metal with a plastic grille and a metal cover.  A particularly nice detail is the control panel at the back with its coloured parts.

The boom sections are metal with hydraulic pipe details in the casting, and the pipework is plastic with an excellent colour match.  .  The connection details at the joints are complex and well done.  The hydraulic hoses are excellent, being thin and soft.

There is a plastic discharge hose at the end, and two extra lengths are included with the model.

Features

The truck rolls smoothly and the front two axles have linked steering which can be posed to a very good angle.  The rear axle can be independently steered although it was not fully grounded on the review model.

The rear outriggers fold out and the front ones extend.  The small pads can be lowered by unscrewing.  The model can be supported wheels free, and the multiple spreader plates give different height options.

At the rear the hopper lid can be posed either open or closed by plugging in which is not quite as nice as a hinge. 

The rear light bar folds to allow a truck mixer to get close to the hopper.

The boom rotates smoothly.

The boom articulation works well and the rams were able to hold almost all poses.

Two lengths of hose are included with the model but there are no connectors.  However, if a join is made then an effective long length of hose can be produced.

Quality

This is a heavy and fairly robust model which gives it the feeling of quality. 

The paint and graphics are excellent.

Price

It is reasonably priced.

Overall

This is a very nice large concrete pump model with some impressive detailing.
