The factor of time is playing an increas-ingly important role in concrete place-ment for large projects. When the reachand options on truck-mounted concretepumps are insufficient, stationary boomsare able to offer efficient concrete place-ment. Used together with stationary con-crete pumps, they provide high-perform-ance and practical solutions. They reducethe time required for placing the concreteand increase productivity.

The MX standardised modular designallows the system to be used economic-ally for various applications, e.g. theconstruction of power stations, caverns,liquid gas tanks and bridges, as well asin building construction.

Booms with 24 to 50 m horizontal reach,with or without counter-weights (up to 36m) in accordance with construction siterequirements, for both climbing form-works and freestanding constructionsites or also auto-climbing, e.g. throughfloors.

This fulfils all requirements regarding thecreation of building and industrial con-structions.

In the initial phase, the freestandingboom, mounted on a tubular column orlattice tower, is used to concrete the baseplate and the first floor.

Following this initial phase, the climbingboom uses the integrated lifting equip-ment to move up through the floors andshafts to the height of the higher floorsstill to be constructed.

On large construction sites, the displace-able boom can be moved from one tubul-ar column to another using the quick dis-connect system.

The main advantages of the MX type series

■ No counter-weight up to 36 m■ Easy to transport and set up■ Short set-up times■ Secure handling■ Grows upwards with the structure■ Small space requirement■ With or without counter-weight

Setup variants

The placing boom can be set up in differ-ent ways■ Freestanding, on a ballastable cruci-

form base■ Freestanding, on the compact cruci-

form base secured on the base platewith foundation anchor

■ Using a cruciform base, secured on aclimbing framework

■ No cruciform base is required if abase plate and floor are present. Thetubular column is held in place byfour base plates and floor cornerguides

The RS 850 system Flexible and quick setup

Using the foundation anchor, the cruciform base can also be attached on a climbing formwork

Attachment to a base plate with anchor embedded in the foundation. If the location iscramped, the compact cruciform base can alsobe attached in the foundation using a tensionanchor basket.

The placing boom can be freestanding if aballastable cruciform base is used

If a floor is already present, no cruciform base is required. The tubular column is then guidedthrough four base plates.

New tubular column

The RS 850 tubular column systemcomes with 3 m, 6 m or 9 m columns asstandard, with standard pipeline lengths.Different tubular columns for setting upthe boom pedestal and arm assembly arenot required. The double M tubularcolumn profile requires only one simple,square cut-out (1 m x 1 m) in the floors.By using an adapter, existing booms cancontinue to be used with the RS 850tubular column.

Automatic climbing procedure

The climbing system integrated in thetubular column profile allows automaticclimbing in the building. Once the climb-ing procedure is complete, the climbingcylinder is drawn upwards along theclimbing bar, using a cable winch (see p.8).

Simple column connection

Instead of the procedure common upuntil now, in which the tubular columnshad to be laboriously screwed together,re-usable pins are used in the RS 850system. They can be simply inserted byhand and secured.

Adapter between tubular columnRS 850 and boom pedestal R 750

Naturally, an existing Putzmeister placingboom (with R 750 boom pedestal) can becombined with the new tubular column.Putzmeister provides an adapter for thispurpose. This allows the benefits of theRS 850 system to be enjoyed with theexisting arm assembly.

Separable platform

One part of the platform can already bedelivered to the construction site, pre-assembled on the tubular column. It canbe immediately and simply installed onthe tubular column. The rest of the plat-form is just latched in and secured. Anoptional safety platform, which is requir-ed by accident prevention regulations insome countries, can also be secured tothe tubular column.

Ladder elements with removable back protection:the screwed-on back protection can be removedfrom the ladder elements for easier transportationand to protect against damage during storage.

Bracing:Special construction site situations require special solutions. If a large freestanding height isrequired (in cavern construction, for instance),the stationary boom can be secured to the struct-ure with a bracing, thereby overriding heights

The RS 850 system Well thought out right down to the last detail

The RS 850 system The quick disconnect systems

The multi-boom disconnection point

Thanks to this disconnection point, plac-ing booms can be used on truck-mount-ed concrete pumps and in stationaryoperation on tubular columns or lattice

towers. The multi-boom disconnectionpoint separates the arm assembly fromthe boom pedestal. The arm assembly isset up and dismantled as one unit.

Two pins secure the boom on the boom pedestal and enable the two to be disconnected quicklyand conveniently for assembly and disassembly

The T disconnection point

In addition to the multi-boom dis-connection point, Putzmeister also offersthe disconnection point in the A arm forthe placing booms with 28 m and 32 mhorizontal reach. This separates theboom pedestal with part of the A armfrom the rest of the arm assembly. Thecrane loads are under 5 to.

What is common to all of these is that theelectric motor, all hydraulic componentsand the boom control are integrated inthe boom pedestal.

The RS 850 system Automatic climbing

Climbing process

Tubular columns climb hydraulically bymeans of a climbing cylinder. The swivelclaw is folded out, the climbing cylinderis positioned on the floor and pushes thetubular column upwards using the upperclimbing carriage (B).

Before the end of the stroke, the catch onthe lower climbing carriage engages inthe climbing bar and holds the tubularcolumn in position (C).After the climbing cylinder's return stroke (C), the catch on the upper climb-

ing carriage engages in the climbing baragain (D).The starting position (D and A) has beenreached. The climbing procedure is com-plete and can be repeated.

After climbing, the tubular column sup-ports itself on the extending feet again.The swivel claw is folded in again, andthe climbing cylinder is drawn upwardsalong the rail by the cable winch (E).

Each tubular column can be connected to the boom pedestal by pins. The slewing gear cylinders have end position damping to reducethe twisting moment on the mounting console.

Practical extending feet hold the tubular columnin the building and relieve the operator of thetask of handling the heavy and unwieldy bolts

Lightweight components

Four lightweight and compact floor corn-er guides replace the heavy floor framesused up until now. The floor corner guid-es can easily be carried to the relevantstorey.Climbing cylinders and locating bolts arereplaced with the climbing system whichis secured on the tubular column and theintegrated extending feet.

The lattice tower systemIdeal for large horizontal reaches

If a project demands a horizontal reachgreater than 36 m, stationary booms onlattice towers are used. These allowhorizontal reaches of up to 50 m, as arefrequently required for the constructionof liquid gas tanks, for instance. Thecomplete Putzmeister stationary boomrange is, of course, also available withlattice towers as the base structure. Adapters provide the appropriate con-nection. (If stationary booms are to be setup on a lattice tower made by a differentmanufacturer, Putzmeister must givetechnical clarification and approval).When a stationary boom is set up on alattice tower, no counter-weight is requir-ed for a horizontal reach of up to 34 m.

Benefits at a glance

■ Can also be used on constructionsites with limited space

■ Lattice towers can be easily adjustedto different heights and floors

■ Various mounting options: to the baseplate, structure or climbing formwork

■ Hydraulic self-climbing equipment ■ Ladders and pipelines are fitted to the

lattice tower in such a way as to savespace

■ Requires only one simple, squarecut-out in the floors

■ The quick disconnect system betweenthe boom pedestal and lattice toweradapter allows the placing boom to beassembled or dismantled quickly
