Аrs для тяжелых поддонов

Stop relying on forklifts to maneuver 2,000kg payloads at dangerous heights. In heavy manufacturing, floor stacking creates “honeycombing” that wastes 40% of your footprint. We convert that risk into a rigid, high-density vertical asset using Q355 steel structures and precise automation. Talk With An Expert

In the realm of heavy industry—whether handling cast iron molds, automotive sub-assemblies, or dense raw material coils—gravity is the primary adversary. Traditional warehousing attempts to fight gravity with forklifts and floor stacking, resulting in a chaotic environment defined by limited verticality and high operational risk.

The Unit-load ASRS (Automated Storage and Retrieval System) fundamentally alters this equation. By transitioning from a manual, planar operation to an automated, vertical strategy, manufacturers can handle heavy pallets (1,000kg to 8,000kg) with a level of precision that manual labor cannot sustain.

Engineering Rigidity: The Double Mast Structure

Handling a standard FMCG pallet is one thing; lifting a 3-ton stamping die to a height of 25 meters is an entirely different engineering challenge. The core failure point in generic warehousing systems is the “whiplash effect” (oscillation) at the top of the mast during high-speed acceleration.

To counteract this, the starack-Standard and Heavy series utilize a Double Mast structure fabricated from Q355 high-strength steel. Unlike welded structures which are prone to fatigue cracks under dynamic heavy loading, we utilize a fully bolted structure. This provides the necessary flexibility to absorb kinetic energy while maintaining structural integrity.

The system anchors the stacker crane via a bottom rail and a rigid top guide rail. This mechanical linkage allows the crane to travel at horizontal speeds of 160m/min with a heavy payload, while maintaining a positioning accuracy of ±3mm. This precision is non-negotiable when interfacing with AGVs or conveyor systems that have zero tolerance for misalignment.

Density Logic: Eliminating the Honeycomb Effect

In heavy manufacturing, floor space is often competing with production lines. A common inefficiency is “honeycombing”—where deep lanes of floor-stacked pallets become inaccessible or partially empty, yet the space cannot be reclaimed. A 10,000 sq. ft. floor stack area might only yield 60% effective utilization due to the need for forklift maneuvering aisles.

Implementing a High Bay Warehouse changes the metric from square meters to cubic meters. By utilizing a Rack Clad structure (where the racking supports the building roof and walls), we can extend storage height up to 40 meters. For specific raw materials that do not require immediate individual access, we deploy multi-deep storage technologies.

This configuration is particularly effective for batch production (e.g., plastic granules, sheet metal) managed on a LIFO (Last-In, First-Out) or batch FIFO basis. It sacrifices immediate selectivity for extreme density, often tripling the storage capacity compared to selective pallet racking on the same footprint.

Kinetic Control: S-Curve Acceleration

When moving heavy pallets, sudden stops or starts are catastrophic. A 2,000kg load carries immense momentum. If a forklift slams the brakes, the load can tip. In an automated system, jerky motion causes vibration that triggers emergency stops.

Our Automated Pallet Storage System utilizes advanced closed-loop control with S-Curve Acceleration. This logic smooths the transition between stationary and moving states, eliminating the “jerk” force. This is critical for liquid loads (preventing sloshing) or unstrapped heavy castings.

Furthermore, the heavy payload becomes an asset during the descent. The hoist motors are equipped with Regenerative Braking Units. As the 2-ton carriage lowers from 30 meters, the gravity potential energy is converted back into electricity and fed into the DC bus to power the horizontal travel motors. This reduces overall energy consumption by 20-30%, a significant OpEx reduction for 24/7 operations.

The Data Handshake: WMS and Production Continuity

A “heavy” warehouse is not just a storage facility; it is a production buffer. The starack system acts as the physical execution arm of your WMS integration. In an automotive context, this means “Line-side Supply.”

When the MES (Manufacturing Execution System) triggers a replenishment signal for an engine assembly line, the ASRS identifies the exact pallet coordinate. It enforces strict FIFO (First-In, First-Out) based on production batch codes, preventing the stagnation of raw materials that leads to rust or expiration.

The system employs laser positioning and profile gauge detection to ensure that every pallet entering the high bay is structurally sound. If a pallet has an overhang greater than 50mm (a common issue with shifting heavy loads), the system rejects it at the induction station, preventing jams inside the rack.

Frequently Asked Questions

1. What is the maximum weight capacity for a single Unit-load ASRS location?
Our starack-Standard handles up to 1,500kg. For extreme applications, the starack-Heavy series is engineered to handle loads between 3,000kg and 8,000kg per unit, specifically for dies, coils, and heavy machinery parts.

2. Can the system handle non-standard pallet sizes typical in manufacturing?
Yes. While standard Euro or GMA pallets are common, heavy industry often uses custom steel skids or bins. We design the load handling device (forks) and the racking pitch specifically to your load dimensions, provided they are consistent.

3. How does the system behave during a power outage with a suspended heavy load?
The hoist motors are equipped with fail-safe mechanical brakes that engage immediately upon power loss, mechanically locking the carriage in place. The system effectively “freezes,” preventing any vertical drop of the heavy payload.

4. Is the floor foundation requirement different for heavy ASRS?
Yes. Due to the high point loads transferred through the rack uprights, a reinforced concrete slab with specific thickness and rebar density is required. We provide the static load calculations for your civil engineers to design the appropriate foundation.

5. Can we retrofit an ASRS into an existing brownfield factory?
It depends on the ceiling height. If your existing facility is below 10 meters, the ROI of a vertical stacker crane diminishes. However, for existing buildings with 12m+ clearance, we can install a self-standing structure. For lower heights, we often recommend Miniload ASRS for smaller parts consolidation.
