Descripción general & Casos de uso

Able Hardware engineers and manufactures custom material-handling carts and racks for warehouse, distribution center (DC), and 3PL operations. Built from structural steel tubes and plates with robotic MIG welding, our carts, dollies, order-pick trolleys, kitting racks, and pallet-sized platforms are optimized for payload, ergonomics, and lifecycle cost. We provide OEM/ODM and custom service for B2B buyers, combining upstream laser cutting, Mecanizado CNC, and export-ready QA.

Why this solution for warehouse & logistics environments

Modern DCs demand durable equipment that rolls smoothly on real floors, resists impacts, and survives continuous duty cycles. Our designs start from the operating envelope—load (150–1,200 kg), duty (manual or tugged), aisle constraints, floor type (concrete/epoxy/tiles), and safety rules. Using jigs and fixtures, we hold tight squareness and flatness on deck assemblies so carts track straight and reduce push/pull forces. Powder-coated or plated finishes protect in humid or high-throughput environments, while standard caster patterns reduce maintenance.

Typical applications in warehouses, DCs, and 3PL operations

Order-picking trolleys with adjustable shelves and scanner mounts
Pallet dollies and skid platforms for inbound/outbound lanes
Kitting carts and line-feed racks for cross-dock or light assembly
Bulk platform trucks with removable corner posts
Tugger carts (mother-daughter or train systems) for milk runs

Opciones de fabricación

MIG automático/robótico (y tig si se especifica), plantillas & accesorios, repetibilidad

We weld frames using automatic/robotic MIG for speed and repeatability; TIG is used where stainless cosmetics or thin-gauge control is required. Custom jigs and locating pins ensure repeatable datums for caster plates and shelf posts across batches.

Operaciones secundarias: corte con láser, doblando, mecanizado; revestimiento & embalaje

Corte por láser & doblando: Clean edges, accurate tabs/slots for self-locating assembly.
Mecanizado CNC: Precision mounting holes and bearing seats.
Revestimiento: In-house or partner powder coating/plating with traceable batch records.
Embalaje & exportar: Palletized or crated with protective wrap, labels, and pcs/pallet optimized for container loading.

Tipos & Geometría

Common assemblies for warehouse & logística (platform carts, order-pick trolleys, pallet dollies, rack frames) & bandas de dimensionamiento

Platform carts: 800×600 to 1600×800 mm decks; removable corner posts; toe guard rails.
Order-pick trolleys: 2–4 shelves, 600×400 or 800×600 footprint, scanner/label mounts, ladder options.
Pallet dollies: 1200×1000 and 1200×800 mm; fork-entry guards; tug eye or tow bar for trains.
Kitting racks: Modular uprights with adjustable arms; anti-tilt features; footprint set by aisle width.
Tugger “daughter” carts: Low-profile frames, central-lock casters, hitch geometry for smooth train articulation.

Caster engineering: Wheel materials PU/nylon/rubber/cast iron; diameters Ø100/125/150/200 mm; aspectos (ball/roller/plain). Typical sets: 2 rigid + 2 swivel, o 4 swivel with brakes or a central lock.

Load math: When turning, assume three casters share the load; choose a safety factor 1.3–2.0. Example: 800 kg payload + 80 kg cart ≈ 880 kg; per-caster design load ≈ (880/3)×1.5 ≈ 440 kg; select casters ≥ 440 kg each. Match tread to floor: PU for epoxy/tiles (low noise), nylon for heavy loads on smooth concrete, rubber for mixed floors.

Ergonomics & seguridad: Handle height suited to operator (typically 900–1100 mm), bump guards, corner protection, toe guards, and noise targets. Minimize push/pull forces by aligning wheelbase and bearing selection to route profiles.
