Vertical conveyor solution (Pocket)
QBF rubber Pocket Lift vertical conveyor addresses application limits of steep angle sidewall belt conveyors. Designed for high lift, high capacity vertical bulk lifting for mining and tunnel projects. Reduce spillage and lower operational costs.
Standard steep angle sidewall belt conveyors operate reliably within set inclination ranges. Yet they hit clear practical limits when tasked with high height, high capacity vertical lifting. As working angles move toward true vertical, conventional corrugated sidewall units run into material roll back, faster belt fatigue, cleat loss and reduced throughput. Site teams see these issues most acutely in deep underground mines and large scale tunnel builds.
QBF rubber pocket type vertical conveyor is built specifically for high lift, high capacity vertical transfer, for jobs where steep angle sidewall belt conveyors cannot deliver acceptable performance.
Full Life Cycle Single Source Support
Like our steep angle sidewall offering, QBF rubber takes full end to end charge of every pocket type project. This approach removes the common industry pain point where multiple subcontractors shift blame once equipment troubles emerge:
Simulation led custom engineering
We run multi physics simulation work to assess shaft layout, pocket filling behaviour, peak steel cord belt tension and cross bar fatigue risk. Real world site inputs including material characteristics, lump size, throughput and lifting height feed every design step. This work heads off known risks such as pocket overload and uneven load distribution before any metal cutting begins.
Purpose built pocket components manufactured in house
Drawing on 50 years of hands on European rubber conveying manufacturing know how, QBF rubber produces heavy duty rubber pockets, cross bar connectors and steel cord reinforced base belts via hot vulcanised workflows. These components stand up to heavy impact, abrasive material and damp underground conditions over long service cycles.
On site fitting and full load commissioning
Our in house field engineers complete shaft mounted installation, precise cross bar alignment, belt splicing and gradual full load performance testing. We resolve hidden mechanical flaws before handing systems over for commercial production.
Condition focused predictive maintenance
Our inspection routines cover steel cord belt integrity, pocket wear levels and cross bar connection status. Planned condition based servicing replaces reactive emergency fixes, which drastically cuts costly unplanned shaft downtime.
Retrofit & upgrade packages
Many older vertical hoisting units develop repeated pocket tearing after years of runtime. QBF rubber offers pocket renewal, cross bar reconditioning, belt replacement and drive system tuning. You do not need full system demolition to boost existing equipment output.
Core Competitive Advantages
Machine Belt Co Engineering, Not Assembled Off the Shelf Parts
Most competing pocket type solutions mix generic purchased frames with third party pocket belt assemblies. At QBF rubber, mechanical and rubber product engineers collaborate starting at early concept work. Shaft frame layout, drive tension settings, cross bar spacing and pocket geometry get fine tuned to function as one unified system. This practical, root level optimisation cuts down familiar failure modes: pocket tear out, loose cross bar fixings and uneven belt tension spread.
Sino German Joint Engineering, European Standard Quality for Global Vertical Sites
QBF rubber’s cross border engineering team taps real world German vertical conveying experience plus established European design benchmarks built for deep shaft machinery. We iterate pocket shapes, vulcanisation sequences and heavy duty tension control hardware to match harsh underground, tunnel and heavy industry operating conditions across global job sites. Clients gain the dependable performance associated with premium imported units, alongside realistic costs from modern localised manufacturing.
Single Point Accountability to Lower Vertical Operation TCO
QBF rubber acts as one single accountable supplier covering mechanical fabrication, custom pocket belt production, on shaft site execution and ongoing predictive maintenance. We take full ownership of overall pocket type system performance. Technicians can adjust operating parameters while equipment stays online, helping contain maintenance spend and avoid expensive shaft related production losses.
Built for jobs where sidewall belt conveyors reach their practical limits
Traditional corrugated sidewall belts struggle with material fallback, fast wearing cleats and throughput drop off under pure vertical, high capacity, tall lift conditions. QBF rubber pocket type uses independently suspended rubber pockets fitted to cross bars between dual steel cord belts. Bulk material remains fully contained through vertical travel, enabling continuous high tonnage runs without intermediate transfer stations.
Direct Global Field Support Using In House Engineering Staff
We keep complex shaft side installation, inspection and repair tasks within our own technical team, rather than farming work out to external subcontractors. Supported by QBF rubber global service hubs, our staff respond quickly for emergency shaft repairs, field belt splicing, equipment modification and scheduled site inspection rounds.
Industry Applications
Core positioning：pocket type applies to high height, high capacity vertical lifting and working scenarios with operational restrictions for steep angle sidewall belt conveyors.
Mining: Intermediate transfer within blind shafts; conveying from muck shafts up to ground surface.
Tunnel construction: Lifting height over 250 m, handling capacity exceeding 800 m³/h.
Metallurgical Steel Plants: Vertical feeding for sinter, bulk slag and raw ore.
Thermal Power Facilities: Vertical handling of raw coal, bottom ash and fly ash by products.
Large scale Bulk Terminals: Special vertical lift segments integrated into port bulk material workflows.
Solution Summary
Operators across bulk handling industries often face an awkward trade off: either use sidewall belt conveyors constrained by vertical lift boundaries, or deploy intermittent skip / bucket hoists that bring frequent downtime. QBF rubber’s pocket type vertical conveyor fills this technical gap. Our competitive strengths come from hands on machine belt co engineering, Sino German joint technical input, in house build for critical pocket belt components and cohesive full lifecycle technical support. For global projects requiring genuine continuous pure vertical bulk material lifting, we deliver robust conveying systems with lower routine maintenance demands.
FAQ
Q: Wht is the key difference between Pocket Lift and steep angle sidewall belt conveyors?
A: Corrugated sidewall conveyors perform best on inclined lifting duties. Their performance degrades in pure vertical, high height, high capacity scenarios, bringing roll back and fast cleat wear. pocket type uses separate suspended rubber pockets mounted on cross bars between dual steel cord belts, purpose built for continuous 90 degree vertical hoisting.
Q: What typical working conditions suit QBF rubber pocket type?
A: It targets high height & high capacity vertical lifting where sidewall belt conveyors hit limits. Typical cases include mine blind shaft intermediate transfer, muck shaft to surface haulage, and tunnel projects with lifting height＞250 m and capacity above 800 m³/h.
Q: Can you retrofit existing vertical hoisting infrastructure with QBF rubber pocket type components?
A: Yes. We supply pocket renewal, cross bar refurbishment and belt swap upgrade packages. Full demolition of existing shaft steelwork is not always required.
