ORIENTATION / LIFTING TECHNOLOGY
Manipulator, crane or chain hoist: Which is used for what?
There are various solutions for lifting and moving loads in production. Which one is right depends on the task, not just the price.
Zeilhofer Handling Technology specializes in manipulators, lifting axes, and lifting aids. Cranes and chain hoists are not part of their product range. This overview is for informational purposes only and is not a sales pitch for any particular system.
COMPARISON OF THE SYSTEMS
THREE SOLUTIONS, THREE TASKS
Cranes, chain hoists, and manipulators solve different problems. The crucial difference lies in whether a load simply needs to be lifted or precisely handled during the process.
Crane & chain hoist
Cranes and chain hoists lift loads vertically and transport them over long distances. The load hangs from a rope or chain and can swing.
They are suitable when a load needs to be moved from point A to point B and the exact position at the destination is less critical. Advantages include high lifting heights, high load capacities, and a comparatively low purchase price.
Limitations become apparent when the load needs to be precisely positioned, rotated, or joined against resistance. A chain hoist cannot handle off-center loads or torques.
Manipulator Zeilhofer HHT
A manipulator guides the load using a rigid mechanism instead of a rope or chain. This prevents the load from swinging.
It can be positioned, rotated, tilted, and joined against defined resistance with millimeter precision. The manipulator can also handle off-center loads and torques.
The right choice when a component not only needs to be lifted but also handled precisely during the process: during insertion, joining, screwing, or alignment. This increases cycle time reliability and ergonomics.
DECISION AID
WHICH SYSTEM FOR WHICH TASK
A quick overview based on use case. In many companies, both systems are used in parallel.
-
Simply lifting and transporting over a distance = MANIPULATOR
-
Millimeter-precise positioning in the assembly process = MANIPULATOR
-
Rotating, tilting, or adding a load = MANIPULATOR
-
Capturing off-center loads or torques = MANIPULATOR
-
Very high lifting heights with simple load handling = CRANE / CHAIN HUNCH
-
Pendulum-free, ergonomic handling in sync = MANIPULATOR
FAQ / Q&A
FREQUENTLY ASKED QUESTIONS
01 What is the difference between a manipulator and a chain hoist?
A chain hoist lifts the load using a chain, which can swing during the process. A manipulator, on the other hand, guides the load via a rigid mechanism; it does not swing and can be positioned, rotated, and joined with millimeter precision. A manipulator can also handle off-center loads and torques, which a chain hoist cannot.
02 When is a manipulator more worthwhile than a crane?
A manipulator is worthwhile when a component not only needs to be lifted but also handled precisely during the process, for example, during insertion, bolting, or alignment. If it's simply a matter of lifting and transporting over a distance, a crane is usually the more economical solution.
03 Can a manipulator replace a crane?
No, they both perform different tasks. A crane transports loads over distances and heights. A manipulator positions loads precisely during the assembly process. In many companies, both systems are used in parallel.
04 Does Zeilhofer also build cranes and chain hoists?
Zeilhofer Handling Technology specializes in manipulators and lifting aids and does not offer standalone crane or chain hoist solutions. However, chain hoists are used as components, for example as lifting units within electric lifting axes.
