Two-column and four-column electromechanical vertical transfer lifts for interfloor logistics
Buffer stacking and destacking stations designed for continuous high-speed assembly flow
Complete compliance with European plant engineering standards and fieldbus protocols

Operating Principles of the Patented Sigma-Drive Flat Belt Transmission

The patented Sigma-Drive (Σ-drive) engineered by HEG Heckert Engineering GmbH provides a modern alternative to traditional hydraulic cylinders and ballscrew actuators in industrial scissor lift tables.

Lifting forces are transmitted purely via friction using high-strength polyurethane flat belts reinforced with high-tensile steel cord cores running over precision drums.

Eliminating hydraulic oil prevents fluid leakage risks, environmental hazards, and viscosity fluctuations across seasonal ambient temperatures.

The drive kinematics generate constant motor torque and steady vertical velocity throughout the travel path, preventing dynamic acceleration spikes during the handling of heavy automotive bodies.

Double Motor Redundant Drive Architecture and Performance Level d Compliance

Heckert Original Double Motor scissor lift tables implement a redundant electromechanical powertrain configured specifically for manufacturing cells where assembly personnel work in close proximity to the lift.

Dual mechanically synchronized geared motors feature electromagnetic holding brakes engineered with double rated braking torque. If a single drive path experiences a fault, the secondary motor independently arrests and holds the rated vehicle payload safely.

This architecture fulfills safety category Performance Level d under EN 1570-1 standards without relying on destructive hydraulic catch cylinders.

Curved Scissor Arm Geometry and Torsional Rigidity in Skillet Systems

Underfloor skillet assembly conveyors and AGV (FTS) lifting stations experience demanding eccentric and torsional stresses as operators step onto the platform to assemble vehicle components.

Heckert Original lift tables utilize heavy-duty scissor arms featuring curved structural profiles that counteract lateral twisting moments. The base and top platform frames are fabricated from structural steel and normalized to eliminate residual stresses.

Four precision guide rollers distribute dynamic floor loads onto hardened runways, ensuring height positioning repeatability within ±1 mm.

Tool-Free Spread Shaft Assembly Replacement and Rapid Maintenance

The mechanical interfaces of Heckert Original lift tables are designed to minimize line downtime in high-throughput automotive manufacturing.

The heavily loaded scissor spread shaft (Spreizwelle) can be detached and replaced without specialized extractors or tooling, while precision self-centering journals eliminate the need for mechanical recalibration after reassembly.

Scissor guide rollers incorporate rapid-release retainers allowing bearing inspection and replacement at any intermediate lift height during scheduled production intervals.

Integrated Fall Protection and SITEMA KSP 28 Safety Catch Systems

In addition to the electromechanical redundancy of the Double Motor drive, Heckert Original integrates pneumatic safety catch devices such as SITEMA type KSP 28 for safety-critical assembly tasks.

The clamping rod is linked directly to the scissor spread shaft and remains concentric with the clamping ring throughout vertical motion.

In the event of emergency power loss or excessive lowering speed, the pneumatic wedge mechanism grips the rod instantly to arrest the descending mass smoothly without permanent structural damage.

Conveyor System Integration, Column Lifts, and Body-in-White Handling

The Förderanlagen product line from Heckert Engineering encompasses comprehensive solutions for material transport and buffer storage in automotive plants.

Offerings include heavy-duty powered roller conveyor beds with variable frequency control, two-column and four-column electromechanical vertical transfer units for multistory parts delivery, and automated pallet destacking units.

Modular structural interfaces allow seamless communication with plant-level MES and PLC networks using standard industrial Ethernet protocols including PROFINET.
