Germany-based Putzmeister (PM), a well-recognised and respected manufacturer of concrete and material placing equipment for the construction industry, will be presenting a cross-section of its extensive range of concrete pumps, placing booms and mobile telescopic conveyors at the Big 5 show.

Putzmeister is the world record holder in high-rise concrete pumping (606 m pumping height) and in the construction of large-boom truck-mounted concrete pumps (placing booms with up to 70 m vertical reach).
As a good example of its range of large truck-mounted concrete pumps, Putzmeister is showing the BSF 63-5.20 H model. With a vertical boom reach of around 63 m, this six-axle machine is the largest truck-mounted concrete pump in the Middle East, states the company.
Despite its size, the BSF 63-5.20 H is characterised by a high degree of flexibility in several respects – for example the five-arm concrete placing boom that not only has a high vertical reach, but also an impressive horizontal working range. The flexibility of the machine is further aided by the variable EFS (ergonic flexible support) system. Explaining the benefits of the EFS system, Putzmeister Concrete Pumps’ press officer Jürgen Kronenberg, says: “Until now, truck-mounted concrete pumps could only be operated on the fully supported side for reasons of stability. The EFS system allows the placing boom to be moved to hitherto forbidden areas if there is limited space available. Thanks to EFS, the number of possible applications is considerably expanded, the net vertical reach is increased, the working capacity is greater and there is, therefore, improved cost-effectiveness for truck-mounted concrete pumps.”
Besides the flexible concrete placing boom and the spectacular support system, the BSF 63-5.20 H that will be on show also has other attention-grabbing features. For example, Kronenberg  points out, it has a high-capacity pump unit that enables outputs of up to 200 cu m per hour – which incidentally is a record amount for a truck-mounted concrete pump.
“Even if outputs of this volume are seldom required,” he says, “these power reserves allow particularly smooth and low-wear operation in the day-to-day running of the machine due to the low number of transfer tube switchovers per cubic metre of concrete. To ensure that can also be mobile on surfaces other than paved roads, the PM long-reach boom pump has four steered and three driven axles.”

Mobile line pump
For not only frequent site changes during high-rise concreting but also when long-distance pumping through long pipelines is required, Putzmeister has designed the mobile high-pressure concrete pump MOLI 2110 HP (Mobile Line Pump). The pump unit is the same as the stationary PM BSA 2110 HP D concrete pump.
“In fact, the world record delivery height of 606 m was set by a modified machine from this range at the Burj Dubai in April 2008,” he states.
The MOLI 2110 HP being presented at the Big 5 show will be mounted on a three-axle Mack truck and powered by a powerful 318 kW diesel engine.
Elaborating on its features, Kronenberg says: “Because the requirements on construction sites can be very varied – one project might require large quantities of concrete while another might need an above-average concrete pressure – the hydraulic system in the MOLI can be converted from rod-side to piston-side operation with a few manual adjustments. Depending on the settings, this PM MOLI can achieve extraordinary limit values: either an output of 106 cu m per hour and a maximum delivery pressure of 150 bar or an output of up to 69 cu m per hour and a concrete pressure of up to 220 bar (pressurised on the piston side).”

Stationary booms
For high-rise concreting, Putzmeister has a range of stationary concrete placing booms with reaches of 24 to 50 m. PM stationary booms sit either on tubular columns or lattice towers and climb – according to the progress of the construction – with the formwork or using their own hydraulic climbing system. Modern PM stationary booms with up to 36 m horizontal reach do not require any ballasting, he says.
At the Big 5, Putzmeister is presenting the MX 32-4 T model, which also has a coupling joint between the boom pedestal and a part of the “A” arm. “Putzmeister has thus reduced the crane weight of the boom components to under 5 tonnes, enabling simplified mounting and removal,” Kronenberg adds.

New tubular column system
Meanwhile, Putzmeister has developed the new RS 850 tubular column system, which carries the boom and can also climb floor by floor – according to the progress of the construction – supported by an automated climbing system. Explaining the concept, Kronenberg says: “The double-M tubular column profile with integrated pipeline requires only a square hole in the floor. The tubular columns are held in the holes by four light triangular brackets at each floor, which can be easily carried by hand – heavy floor frames are not an issue at Putzmeister. The usual climbing cylinders and locating bolts have been replaced by integrated push-out feet and the climbing system that is attached to the tubular column and together climbs with it.”
The RS 850 tubular column system and the individual steps of the automated climbing process will be explained in detail during the Big 5 using a model exhibited there.

Telebelt conveyors
Putzmeister will also promote a range of Telebelt mobile telescopic conveyors at the show
Commenting on the purpose of these telescopic conveyors, Kronenberg says: “During construction, not only concrete is pumped and placed, sand, gravel, hardcore, lean-mix concrete, top soil and substrate for green roof coverings, must also be transported and often across various obstacles. Because these mostly dry bulk materials cannot be pumped, Putzmeister has developed a range of Telebelt mobile telescopic conveyors to transport these materials. Among the most powerful Telebelt models is the TB 130, which Putzmeister is presenting at its stand at the show.”
The machine has a hydraulically-driven, pivoting and almost 12-m-long feed conveyor that receives the materials – supplied by a wheel loader, for example. The feed conveyor transfers the bulk materials to the actual conveyor belt which runs on a 5x telescoping boom. On the Telebelt TB 130, the conveyor belt has a horizontal reach of nearly 39 m and can be set to an angle of up to 20 degrees. The maximum theoretical capacity is 275 cu m per hour. The diameter of the materials to be conveyed can be more than 100 mm.
Comprising 16 manufacturing and sales operations worldwide, Putzmeister employs more than 3,200 people and generates more than $1.1 billion in consolidated annual sales.
For decades, the company has had an exemplary service network and highly qualified customer services employees in the Middle East. During the Big 5 show, therefore, the Putzmeister stand will not only present cutting-edge technology, but will also offer the opportunity to discuss cooperation for challenging future projects
The company is located at Stand OC10 and OD 15.
