Why do steel mills adopt trackless transfer carts for steel coil transportation? The DWP series coil transfer cart stands out as one of the most practical heavy-load handling solutions for steel coil movement.
As ideal transport equipment for coiled materials, DWP electric flat carts are widely applied in steel manufacturing workshops, where steel coils act as core production goods. A single steel coil generally weighs 10 to 50 tons, with maximum weight reaching 80 tons.
Steel coils go through hot rolling, cold rolling, galvanizing, color coating, warehousing and cross-workshop turnover throughout production. Every transfer step poses tough challenges and plays a vital role in normal production flow.
Forklifts and overhead cranes are not ideal choices for steel coil handling, while coil transfer carts deliver far better performance. Here are the detailed comparisons:
1.ForkliftsForklifts are conventional handling tools with decent cross-workshop mobility. Yet they are not fit for heavy steel coil transport. The equipment runs unstably and easily tips over. Operators face limited sight range during driving, greatly raising onsite safety risks.
2.Overhead cranesCranes cost a fortune and lack flexible operation. Staff often spend much time waiting for available cranes. Besides handling steel coils, workshops store and move various raw materials, which leads to frequent queuing. What’s more, cranes cannot carry goods across workshop boundaries.
3.Trackless transfer cartsAs our star DWP model, trackless carts keep the flexible moving performance of forklifts and travel freely between different workshop areas. Workers can control the cart remotely, keeping a safe distance while monitoring running status. Emergency stop can be activated instantly once faults occur. Built-in obstacle avoidance devices and sound-light alarms also remind nearby staff, creating a much safer working environment.
Electric coil transfer carts boast multiple practical strengths that perfectly match actual workshop working conditions.
Core merits of trackless transfer carts
Fitted with polyurethane wheels, rechargeable batteries and diverse steering structures, these carts can adjust flexibly and adapt to various onsite working scenarios.
Steel mill floors are mostly paved with concrete or steel plates. Users can pick suitable wheels including polyurethane wheels, solid rubber wheels and large patterned rubber wheels. No floor renovation is needed, ensuring steady operation and extending wheel service life.
Multiple practical steering modes
Workshops and warehouses differ greatly in space size and layout. Multiple steering designs help carts travel smoothly under limited space conditions.
Differential steering: 360-degree rotation and forward-backward travel with compact turning radius
Hydraulic steering: Stable straight running, maximum ±40° turning angle similar to car steering
Omnidirectional steering: Four independent driving wheels support forward, backward and side movement, plus in-situ 360° rotation with zero turning radius
Dual-drive dual hydraulic steering: Dual hydraulic axle structure realizes ±45° turning. The cart maintains stable running both in straight travel and turning.
Superior safety performance in steel coil transport
Solid load-bearing structure protects steel coils from damageThe cart adopts thickened box beam frame made of high-strength Q235B and Q345B steel plates. It bears heavy loads steadily and keeps intact without deformation even carrying coils over 50 tons.
Steel coils are cylindrical and prone to rolling during transit. Custom V-shaped brackets and detachable saddle holders firmly fix coils in place, avoiding sliding and rolling during startup, braking and turning. The smooth running effectively prevents surface scratches and shape distortion, preserving finished product quality.
Running speed can be adjusted from 0 to 20 meters per minute with precise control. Compared with bumpy forklift transport, DWP carts deliver stable travel, safely conveying hot rolled coils and high-precision cold rolled coils alike.
Comprehensive safety protection system safeguards personnel safetyFull-range safety devices guarantee reliable operation. Laser sensors detect barriers within 400 meters, triggering automatic deceleration and emergency braking timely. Continuous sound-light warning reminds surrounding workers. Overload protection, physical emergency buttons and power-off brake functions effectively avoid heavy-load accidents.
Remote wireless control works within 50 meters. Operators control startup, steering and speed from safe areas, staying away from high-temperature coils and falling heavy objects. The equipment suits harsh high-risk working zones like hot rolling workshops perfectly.
Energy-saving high efficiency cuts operational costsEquipped with durable maintenance-free batteries, the cart works continuously for 4 to 6 hours after full charge, meeting round-the-clock multi-shift production demands. Zero emission and low noise fully satisfy industrial environmental standards.
It saves large sums on track laying and daily maintenance compared with rail transfer carts. Fuel consumption and frequent repair costs are lower than forklift operation. Handling efficiency rises 2 to 3 times versus manual work, cutting labor expenditure remarkably.
The cart features strong versatility. Removing V-shaped holders allows transport of steel plates, molds and other heavy workpieces. One device fulfills multiple transport needs and lowers overall equipment procurement cost.
Key problems solved for steel industry users
Break fixed travel limits and reduce renovation costNo ground tracks are required, leaving original workshop floors intact. Factory layout adjustment and production line upgrade need no extra structural reconstruction, saving massive track construction and maintenance expenses.
Avoid coil damage and stabilize product qualityV-shaped fixing design and smooth running prevent coil scratches and deformation. Product rejection rate drops and qualified yield improves, bringing tangible economic gains.
Improve handling efficiency and lift production capacityFlexible omnidirectional movement, strong load capacity and long battery life speed up cross-workshop and cross-process coil delivery. Secondary handling time is shortened, boosting overall logistics efficiency and supporting production expansion.
Lower safety hazards and standardize productionRemote control and multi-layer safety protection keep staff away from heavy high-temperature coils. Onsite accidents get effectively reduced, complying fully with industrial safety production norms.
Control long-term expenditure and enhance competitivenessLow energy consumption, multi-functional usage and simple maintenance help enterprises slash long-term operating costs and strengthen market competitive strength.
