1. Product Overview
Our TL Open-Type Stainless Steel-Aluminum Cable Drag Chain is a
specialized heavy-duty cable management system, engineered
exclusively for the high-stress, high-vibration environments of
transport and construction machinery—from excavators and cranes to
cargo loaders and heavy-duty trucks. Unlike fully enclosed or
all-plastic drag chains, its unique stainless steel-aluminum hybrid structure and open-type design balance rugged protection with easy
maintenance: the stainless steel components resist rust and impact,
while the aluminum alloy parts reduce overall weight without
sacrificing rigidity. This combination makes it ideal for outdoor
construction sites (exposed to dust, rain, and debris) and
long-haul transport fleets (needing durable, low-maintenance cable
support).
Beyond durability, the chain’s thoughtful design elevates equipment
aesthetics: galvanized chain plates create a sleek, modern
appearance, while the neat cable organization eliminates messy
wiring—greatly enhancing the overall artistic look of machinery.
Whether for new equipment assembly or old chain replacement, it
integrates seamlessly with transport and construction machinery,
ensuring stable cable/tube guidance during frequent reciprocating
movements.
2. Core Structure & Material Advantages
The drag chain’s main body consists of three key components, each
selected for industrial performance:
- Chain Plate: Made of galvanized stainless steel/steel—features a novel, clean
appearance and reasonable structural design, with strong corrosion
resistance (critical for outdoor construction) and impact
resistance (to withstand debris collisions).
- Support Plate: Crafted from lightweight aluminum alloy, available in three types
to match different installation needs:
- Integral Type: One-piece design for quick, stable installation on
compact machinery (e.g., small transport vehicles).
- Split Type: Detachable structure for easy cable/tube replacement—no
need to disassemble the entire chain, saving maintenance time.
- Frame Type: Reinforced frame structure for heavy-load scenarios
(e.g., large construction cranes with multiple thick cables).
- Separator: Made of high-quality nylon, offered in white and
black—effectively separates different cables/tubes to avoid
friction and tangling, while adding flexibility to the chain’s
bending movement.
Collectively, these materials deliver two key benefits: strong rigidity (no deformation under load) and enhanced wear resistance—ensuring the chain stays stable even during frequent reciprocating
motions, and extends the service life of internal cables/tubes.
3. Material & Long-Term Performance
| Performance Indicator | Details |
|---|
| Core Materials | Stainless steel + steel (chain plate): Good toughness and wear
resistance; Aluminum alloy (support plate): Lightweight, rigid;
Nylon (separator): Wear-resistant, flexible. |
| Operational Life | Under normal use (standard load, regular cleaning), supports up to 5 million reciprocating motions—far exceeding the service life of plastic drag chains, reducing
replacement frequency and maintenance costs. |
4. Professional Selection Guide (Height & Width)
To ensure the drag chain fits your machinery’s cables/tubes
perfectly (and avoids squeezing or tangling), follow these two core
selection rules (reserve 10% extra space for safe movement):
- Height Selection: Take the maximum height of built-in components (cables, tubing, tracheas, conduits) as the
reference. The drag chain’s inner height must leave at least 10%
remaining space—prevents damage from vertical compression during
bending.
- Width Selection: Calculate the total sum of outer diameters of all built-in components. The drag chain’s inner width must have
at least 10% remaining space—avoids friction between cables/tubes
during horizontal movement.

6. Key Advantages for Transport & Construction
- Hybrid Material Durability: Stainless steel + aluminum alloy resists rust, impact, and
deformation—perfect for outdoor construction and long-haul
transport.
- Open-Type & Easy Maintenance: Split support plates and open structure allow quick access to
cables/tubes—no need to disassemble the chain for inspection or
replacement, cutting downtime.
- Flexible Bending: Wear-resistant nylon separators enhance bending flexibility,
adapting to the frequent reciprocating movements of machinery
(e.g., crane arms, truck lift gates).
- Aesthetic Upgrade: Galvanized chain plates and neat cable organization improve
machinery appearance, aligning with modern industrial design
standards.
