DLZ Series Power-driven Wheel Brakes: Installation Methods & Matching Accessories

 

 

1. Installation Methods

DLZ series electro-hydraulic wheel brakes take horizontal wheel hub side clamping mounting as the standard configuration, and custom vertical transition brackets can be supplied for narrow horizontal bogie layout. They are supporting braking components for industrial trolleys, port container spreaders, mining transfer vehicles and rail wheel sets.

Standard Horizontal Wheel-Side Mounting

Fasten the brake base firmly on the vehicle bogie frame with high-strength anti-loosening bolts. Keep the caliper body perpendicular to the wheel friction ring to ensure symmetrical and full contact between double-sided friction blocks and the wheel friction surface.

Install the matched ED series electro-hydraulic thruster horizontally on the caliper side. Guarantee the thruster push rod moves parallel to the wheel without deflection to output balanced clamping thrust.

Reserve sufficient maintenance space around the wheel hub for friction block replacement, clearance calibration and daily thruster inspection.

Symmetrically arrange multiple DLZ brakes on left and right wheel sets according to the vehicle load and braking torque demand to avoid unilateral braking deviation.

Optional Vertical Custom Mounting

Suitable for compact mining vehicles and small transfer trolleys with limited horizontal space. Special transition brackets are required for vertical assembly. After installation, recheck the thruster internal oil level and reset spring stroke to prevent incomplete release or insufficient braking force.

Core Installation Requirements

All sliding guide mechanisms adopt maintenance-free self-lubricating sleeves, no regular greasing required after installation.

Thoroughly remove mud, oil stains, rust and dust on the wheel friction ring before trial operation; oil contamination will seriously reduce friction coefficient and braking safety.

Adjust single-side gap between friction block and wheel ring via built-in fine-tuning screws, standard clearance: 0.5–1.0 mm on each side.

Fail-safe working logic: Power on the electro-hydraulic thruster to retract friction blocks and release the wheel; power failure triggers built-in preloaded springs to push blocks tightly against the wheel for automatic safety braking.

Avoid strong impact and vibration on the thruster during vehicle operation to prevent internal oil leakage.

2. Standard Matching Accessories

Core Functional Supporting Components

ED Series Electro-Hydraulic ThrusterExclusive driving unit for DLZ wheel brakes, multiple specifications (ED23/5, ED50/6, ED80/6) for different torque grades. Flameproof BEd thrusters are matched for underground mine and chemical hazardous zones.

Manual Release LeverFor manually retracting friction blocks during power failure, vehicle overhaul or manual wheel shifting without power supply.

Status Limit SwitchesDetect fully-clamped braking and fully-released traveling states, transmit real-time feedback signals to vehicle PLC control system for safety interlock and fault alarm.

Consumable Spare Parts

Bolt-fixed quick-replace friction blocksHigh wear-resistant high-friction friction blocks; single-side independent replacement without dismounting the whole brake caliper. Semi-metallic friction blocks are optional for heavy-load frequent braking vehicles.

Complete Adjustment & Fastener KitContains gap adjusting screws, spring preload lock nuts, anti-loose bolts and sliding guide sleeves for long-term parameter recalibration.

Thruster Sealing Repair KitIncluding piston oil seals, dust-proof gaskets and O-rings to eliminate hydraulic oil leakage faults of the thruster.

3. Optional Custom Accessories

Explosion-proof thrusters and Ex-certified limit switches for underground mining transport vehicles and chemical explosion-proof equipment.

Special vertical transition brackets customized for compact bogie layout.

Dust, mud and splash-proof protective covers for outdoor port, mine and construction vehicle working conditions.

Anti-corrosion coated caliper body and stainless steel fasteners for coastal salt fog, humid corrosive environments.

Buffer damping assemblies to reduce braking impact, vibration and running noise for precision handling trolleys.
