Pit‑less Reciprocating Lift for Hygiene Products｜14.5m, 4 Stops, 96 Pallets/Hour

POSTED: 6/5/2026

Visão geral

Tipo de projeto: Chain reciprocating lift (pit‑less installation)
Setor: Hygiene products (diapers, sanitary napkins, tissue paper) – production & warehousing
Principais recursos: Pit‑less (100mm concrete slab + steel plate), 14.5m ultra‑high travel, 4 stops / 4 levels, 40 m/min high speed, 96 pallets/hour throughput, 16 roller conveyor sections, triple fall protection

The client producing disposable hygiene products such as diapers, sanitary napkins and wet wipes. These products are bulky, lightweight and have extremely high dispatch frequency, often stored in multi‑floor warehouses. With e‑commerce and retail demanding “same‑day delivery”, the factory needed fast, stable and automatic material flow from basement (raw materials/packaging) to the third floor (finished goods).

Desafios

1. Não há poço disponível: O local não tem fosso e não pode suportar um elevador tradicional de fosso profundo.
2. Espaço apertado que requer torneamento de material: O acesso direto é impossível - o material deve mudar de direção dentro do eixo (acesso em forma de Z).
3. Alta velocidade de ciclo: Velocidade de elevação de até 60 m/min com transferência automática do transportador para minimizar o manuseio manual.
4. Compatibilidade com vários paletes: Deve manusear dois tamanhos de paletes - 1150×1150 mm (9 pernas) e 1200×800 mm (grade) - com entrada pelo lado mais longo.
5. Altos padrões de segurança: As peças automotivas são sensíveis a impactos e arranhões; são necessárias cortinas de luz, detecção da dimensão da carga e proteção redundante contra quedas.
6. Diferença de altura no mezanino do 2º andar: A plataforma de aço pode não estar perfeitamente alinhada com a alimentação do elevador; é necessário ajustar a altura.
7. Entrega urgente: Pedido feito em 29 de dezembro, envio obrigatório até 30 de janeiro (incluindo o feriado de Ano Novo).

Soluções

3.1 Pit‑less high‑travel design

• Estrutura: Main frame made of 100mm square tube, connectors 100×50×6mm rectangular tube – rigid enough for 14.5m travel.
• Instalação: A steel plate is laid on the existing 100mm concrete slab to increase bearing area. The lift is anchored via foundation bolts. Car infeed height is adjusted by conveyor levels – no pit needed.
• Trilhos de guia: T90 car rails + TK5A counterweight rails ensure vertical accuracy over 14.5m.

3.2 Precise 4‑stop levelling

• Travel & stops: Total travel 14,500 mm, stopping at basement, 1F, 2F and 3F (4 levels).
• Posicionamento: Level sensors on each floor; PLC memorises positions; levelling accuracy ≤ ±5 mm.
• Direção de acesso: Single‑side entry/exit along 3,500mm direction, fitting the factory layout.

3.3 High‑speed, high‑frequency drive system

• Motor: High‑power VFD motor (not explicitly rated, but sized for 16B chains and 40 m/min).
• Taxa de transferência: 40 m/min lift speed, 500kg capacity, single cycle approx. 40 seconds – achieving 96 pallets per hour.
• Reversible operation: Both conveyors and lift can run forward/reverse for bi‑directional material flow.

3.4 Full‑floor roller conveyor integration (16 sections total)

Localização	Conveyor specification	Quantidade
In‑car	L1800×W1800mm (internal width)	1
B1	L1600×W1600×H600mm (standard roller)	5
1F	L1600×W1600×H90mm (three‑section)	5
2F	L1600×W1600×H90mm (three‑section)	3
3F	L1600×W1600×H90mm (three‑section)	3

• Each conveyor width 1600mm, compatible with pallet jacks and pallet size 1100×1300mm.
• Conveyors are interlocked with the lift: each conveyor section maintains a load‑detected state; PLC controls start/stop.

3.5 Triple fall protection & intelligent monitoring

• Mechanical fall protection: Speed limiter + safety gear + lifting mechanism (elevator‑grade) – automatically locks the car if overspeed occurs.
• Electrical safety: 10″ touch screen on each floor shows dynamic simulation, real‑time position, fault codes; audible/visual alarm on fault.
• Data statistics: The touch screen records daily and cumulative cycles – useful for production management.
• Enclosure & guarding: Yellow diamond mesh on four sides; yellow guardrails with warning signs on both sides of conveyors.
