Processes:The Slitting-Process concept (A) is one of

the Dotec total Roll-Handling solutions. The

(RDT) Trolley removes the complete batch

of rolls from the shaft, the RH90 handler

tilt the rolls for palletizing. This speeds-up

the packaging process considerably and

full use of the slitter/converter Speed is

achieved.

Roll distribution (B/C) is an intensive pro-

cess. Rolls must lifted and tilted from the

pallet to the discharge positions. Lifting

& Tilting can be done, centralized in the

warehouse area. Smart roll-carts bring

them to the packaging dept. High efficiency

and little physical effort is the result.

A Dotec LiftAssist have very specific characteristics

that has been based on ease of operation, speed of work and

ergonomics in posture. The learning curve is very short. Work

becomes a pleasure. Dotec The Friendly LiftAssist®.

Dotec ErgoHandle ®The central feature of the Dotec lift assist

is the ergonomic handle, which is used

to operate the lift assist. The handle can

move freely up and down sliding through

the hands, allowing the user to keep his

eye on the load, while a mere finger touch

determines both direction and speed.

There is no need for bending and stretch-

ing (gymnastics) when lifting and storing

in high places (or vice versa).

Extra functions are activated by finger-tip

touch of the levers at the sides. Without

distraction or requiring special attention,

likewise the steering wheel of a car. Not

round but right-angled, since we move

Up&Down.

Smart logic Controls! (Fully pneumatic)The Dotec LiftAssist guides the process through the following

stages: from empty to full – moving – putting down – from full,

back to empty (Release) (Automated sequence). Extra func-

tions can be added and operated without using any buttons

or switches. This makes operation foolproof. The logic controls

responds automatically (proportional) to the user’s movements

and follows his own work speed.

Compact valve-modules have been

developed to achieve high speed reac-

tion and avoid (speed) losses through

long pneumatic tubing. They are in the

centre of each logic control.

The Air-Balancer: (IR-Zimmerman)The air-balancer is the “muscle” of the system and makes

the elastic vertical movement possible.

The compressed air pressure is on both sides of the pis-

ton, which makes that the load is “in balance”. By letting

in additional compressed air on one side of the piston

and escaping air on the other side, the piston moves. The

piston rod is connected to a ball-screw, which is con-

nected to the reel. In this way the linear movement of

the piston is turned into a turning movement of the reel,

which means that the wire rope winds up and unwinds.

In fact, the load is permanently supported (in balance)

by an air cushion. The elastic effect is the result of the

compressibility of air. This principle explains the differ-

ence between the operation of an

Air-balancer and a Hoist.

The logic control unit permanently

measures the “pressure” in the

piston chamber and uses this

information to react.

Once the lifting weight is “In Ba-

lance” only little extra effort (pres-

sure) is needed to move the load

UP & Down.

This all creates the typical

Dotec Dynamics!

Dotec ABC-System:The ABC-System is based on an Air-

Balancer Cylinder instead of the Cable

Air-Balancer. It has the same “Balance”

elastic movement. It’s ment for higher

loads up to 250KG.

ZA- Logic Control: Activated by the Ergo-Handle®, the

basic ZA-logic control allow the com-

pressed air to enter into the Balancer

for the up/down-movement. The valves

react “proportional”, which means that

“pressing” the operating lever harder

results in a “quicker” up & down move-

ment. This makes

operating the lift

assist quick and

dynamic, or quiet

and accurate,

whatever way

of operating the

process requires. This gives the

operator the feeling that he (or she)

decides what happens or should

happen, which creates positive mo-

tivation and an acceleration of the

overall process.

Centre of gravity:An important feature in every

Dotec system is the automated

“Centre Of Gravity” adjustment.

This unit secures the horizontal

and vertical alignment under any

condition.

This means that an empty or

loaded handler will always adjust

itself into the correct position. Once

adjusted for the application, it will

align automatically.

Dotec Articulating Arms have very special hinge points. This

design makes that the well-known disadvantages of the Banjo

arm belong to history. In all directions the Dotec folding arm fol-

lows the movements of the operator in a direct line and will not

straighten.

To reach under e.g. a platform we developed the FlexArm® (type

D). With this arm the rolls until 80 kg can be taken from the pallet

in upright position and placed on the machine shaft in horizontal

position.

Type E is also available in Super light but

Super strong carbon-fiber. Weight reduc-

tion over the steel version > 68%.

Jib cranes are perfect for short transfer applications.

Aluminium rail for the boom is applied, resulting in an

ergonomic, lightweight, easy to move boom. Jib cranes

can be floor mounted on a column or ceiling mounted. Jib

cranes provide up to 360 degrees of rotation and boom

lengths to 5 m.

An accurate and heavy-duty pivot bearing allow smooth

and free 360º rotation. End-stops, with hydraulic damp-

ing, limit the radius, when neces-

sary. A pneumatic parking brake

secures a safe way of parking

the machine, when not in use.

Model C Low Headroom (max.

125 kg) can be applied in loca-

tions with low ceilings.

Dotec infrastructure:

There are four solutions for the infrastruc-

ture: A: Aluminium rail system; B/C: 360°

Rotating arm; D: FlexArm®; E: 700C folding

(Banjo) arm, also available in super-light car-

bonfiber. The smooth operation of a lift assist

highly depends on the correct “infrastruc-

ture”, needed for the horizontal movements.

The infrastructure to be selected strongly

depends on the area lay-out of the factory

and the way of buffering the material that

must be lifted.

Our aluminium rail profiles are extruded from

6063-T6 and anodized for a smooth, clean,

corrosive-free surface. The enclosed rail

design reduces the accumulation of dirt and

grime on the internal running surfaces, thus

reducing rolling effort. The special rail pro-

file, the unique way of suspending and the

advanced trolley design guarantee a rolling

resistance of ≤1% of the load to be moved.
