Transport vehicle

Transport vehicles are the backbone of every construction logistics. They deliver tools, attachments, and materials to the point of use and ensure continuous operations in concrete demolition, special demolition, rock demolition, tunnel construction, and natural stone extraction. In projects where concrete demolition shears, hydraulic rock and concrete splitters, hydraulic power packs, combi shears, Multi Cutters, steel shears, or tank cutters are used, the quality of the transport chain determines cycle time, safety, and cost-effectiveness. This article examines the topic comprehensively-technically sound and practice-oriented-and situates it within the typical fields of application of Darda GmbH. It consolidates current practice, essential standards, and proven procedures for planning and operating safe, efficient transport chains on demanding sites.

Definition: What is meant by a transport vehicle?

A transport vehicle is a vehicle that moves loads, equipment, or gear between locations. This includes road vehicles such as flatbed trucks, box vans, crane trucks, and low loaders, as well as site-capable crawler carriers, dumpers, or in-plant material handling equipment. In the context of demolition and extraction, they transport attachments (for example, concrete demolition shears), stone and concrete splitters, hydraulic power packs, hoses, protective covers, as well as auxiliary and operating supplies. The transport vehicle must be distinguished from the carrier machine: an excavator or a compact loader can move loads, but its main function is working with attachments; a transport vehicle is primarily designed for the safe and compliant movement of loads. Depending on jurisdiction, they may be treated as commercial vehicles or mobile machinery, which affects permitted dimensions, required securing measures, and operator qualifications.

Function and types of transport vehicles on the construction site

Transport vehicles handle three core tasks: delivery, on-site transport, and return. They differ by area of use (road vs. construction site), build (box, flatbed, low loader, crane superstructure), drive (diesel, electric, hybrid), and accessibility (low-floor, low overall height for tunnels, high ground clearance for rough terrain). For heavy attachments such as concrete demolition shears or steel shears, low loaders with ramps and adequate lashing points are common; for modular stone and concrete splitters, flatbed vehicles with systematic load segregation and short setup times are suitable. Hydraulic power packs are often transported on pallets or in equipment boxes to carry hoses, couplings, and protective hoods in an organized manner.

• Modularity: stake pockets, racking, and removable sideboards enable fast reconfiguration
• Interface readiness: lifting points, fork pockets, and crane rails shorten handling times
• Protection packages: splash-proof boxes, covers, and guards for sensitive hydraulics

Use in concrete demolition and special demolition

In concrete demolition, the transport vehicle must deliver tools, power supply, and accessories with pinpoint accuracy. Routes are often narrow, the load-bearing capacities of floors/ceilings limited, and emissions and noise sensitive. Logistics therefore plans the sequence: first hydraulic power packs, then attachments such as concrete demolition shears, and finally consumables and protective equipment. In special demolition-such as on sensitive building structures-low axle loads, compact dimensions, and precise load securing are crucial. A well-thought-out transport shortens setup times, reduces downtime, and increases safety. Where monitoring concepts apply, logistics aligns with vibration-, dust-, and noise-restricted work windows and specifies low-emission handling where feasible.

Transport of concrete demolition shears

Concrete demolition shears have high dead weight with relatively compact dimensions. The center of gravity is often asymmetrical by design. Adequately dimensioned lashing points, edge protectors, and anti-slip underlays are required. Mounting plates and quick couplers are secured, moving jaws are fixed with transport locks. During crane loading and unloading, easily accessible lifting points facilitate safe handling. On traffic routes apply: lash loads down, cover protruding parts, cap hydraulic connections.

• Use form-fit chocks or blocking to prevent micro-movements on flatbeds
• Apply color-coded tags for verified transport position and jaw lock status
• Before loading, relieve residual hydraulic pressure and close protective caps

Transport of stone and concrete splitters

Stone and concrete splitters consist of cylinders, wedges, tie rods, and hydraulic hoses. Sensitive surfaces are protected, wedge sets transported separately and labeled. Hoses must be secured against kinking, couplings covered dust-tight. Temperature management is important: oils and seals react sensitively to extreme cold or heat. For longer trips, low-vibration stowage and separate storage of sharp-edged components are recommended to avoid damage.

• Bundle hoses with reusable straps and add abrasion sleeves at contact points
• Store wedge sets in dedicated inserts, labeled by size and splitting force
• Keep spare seals and protective covers with the kit to reduce setup delays

Safely transporting and staging hydraulic power packs

Hydraulic power packs feed concrete demolition shears, combi shears, Multi Cutters, steel shears, and splitting cylinders. They are transported upright, secured against tipping, and positioned so that the controls remain accessible. Ventilation openings must not be covered. Fuel or power supply is decoupled, and drip trays are kept ready when working with liquids. After transport, perform a functional check: hoses, couplings, filters, fill level, tightness. When specifying or staging these systems, align dimensions, interfaces, and operating parameters with current Hydraulic Power Units. For electric supplies, route cables away from pinch points, use residual-current protection where applicable, and ensure mechanical protection on edges; for fuel-driven units, keep appropriate fire extinguishers and spill kits ready and mark ventilation paths clearly.

• Place power packs on anti-slip mats and position them positively against stop strips
• Select lashing angles and lashing equipment according to the load case, protect edges
• Separate hydraulic hoses, fit the ends with protective caps
• Keep the operating manual at hand, observe hazardous substance notices
• Select a level, ventilated setup location away from ignition sources

Load securing: principles and procedure

Load securing is based on applicable regulations and recognized rules of technology. The goal is to secure loads against sliding, tipping, rolling, or falling. In practice, a combination of friction-enhancing underlays, positive-fit arrangement, and direct lashing has proven effective. Statements regarding legal issues are general and do not replace an individual assessment. Consider dynamic influences such as acceleration, vibration, and emergency braking when defining the securing method and safety margins.

1. Determine load and vehicle: mass, dimensions, payload, axle loads, lashing points
2. Select the securing method: tie-down lashing, direct lashing, slings, or a combination
3. Increase the friction coefficient: clean loading deck, anti-slip mats, dry substrates
4. Protect edges and sensitive components: edge protectors, padding
5. Stow small parts and accessories separately: boxes, partitions, locks
6. Control and documentation: visual inspection, re-tensioning, photo/checklists

Pre-departure checks

• Verify lashing capacity, number of lashings, and angles against the load case
• Check straps, chains, and fittings for wear, cuts, deformation, or corrosion
• Confirm clearance to moving parts, sightlines, lighting, and license markings
• Secure loose items, lock storage boxes, and confirm ramp and door locks

Transport vehicles in tunnel construction and rock demolition

In tunnel construction, low overall height, narrow width, robust lighting, and reliable brakes are key. Exhaust and noise limits are often strict; electrically driven transport vehicles or locally low-emission solutions can offer advantages. Gradients, wet rock, tight radii, and changing friction conditions require sure-footed tires or tracked undercarriages. In rock demolition, loading is often irregular: splitting cylinders, wedge sets, and tank cutters are stowed so that shocks and vibrations are absorbed. Electrical and hydraulic components benefit from high ingress protection, sealed connectors, and corrosion-resistant surfaces under persistent moisture and dust exposure.

Supplying the tunnel face and heading

Short cycle times demand precise supply: hydraulic power packs, splitting cylinders, and wedge sets are provided in clearly defined modules. Returns (blunt chisels, blunt wedges, damaged hoses) are transported separately and marked. Illuminated loading zones, highly visible markings, and weather-resistant labeling facilitate material flow.

• Pre-kitted modules reduce waiting times: splitter + hoses + guards + documentation
• Define return paths and quarantine areas for damaged items with clear signage
• Use rugged, non-slip mats and wheel chocks in loading bays on gradients

Logistics planning, setup times, and interfaces

An effective transport concept reduces unnecessary trips and setup times. Tools are preconfigured on pallets or mesh boxes, slings and lashing straps are firmly assigned. Loading and unloading areas are level, load-bearing, and free of obstacles. Communication between site management, equipment operators, and transport coordinates time windows for changing attachments such as concrete demolition shears, combi shears, and Multi Cutters.

Digital coordination and data

• Time-slot management and geofenced access reduce congestion and idle times
• Telematics support payload awareness, route guidance, and maintenance scheduling
• QR-coded tool kits enable fast identification and checklist-driven handovers
• Photo documentation of load securing improves traceability and quality control

Selection criteria for the right transport vehicle

The selection depends on the type of operation, site conditions, and tool portfolio. In addition to technical metrics, ergonomic and organizational aspects also matter.

• Load capacity and dimensions: loading deck length, lashing points, clearance and ceiling heights
• Driving dynamics: turning circle, gradeability, braking performance, maneuvering assistance
• Drive and emissions: electric or low-emission solutions for indoor areas and tunnels
• Loading concept: flatbed with stakes, box body with racking system, low loader with ramps
• Superstructures: loading crane, winch, tool boxes, drip trays
• Power and hydraulic needs at the point of use: power pack transport, cable/hose management
• Environmental conditions: dust, moisture, cold/heat, corrosion protection
• Permits and qualifications: access rights, weight limits, driving authorizations (general, not legally binding)
• Visibility and safety: cameras, lighting, signaling, and guard rails for elevated work areas
• Energy management: charging or refueling logistics and range planning for multi-shift use

Special requirements in special operations

In sensitive environments such as hospitals, city centers, or listed structures, noise, vibrations, and exhaust gases must be minimized. Transport vehicles with quiet drives, clean emission behavior, and precise maneuverability have advantages. Floor and edge loads must be observed, especially on slabs with limited load-bearing capacity. In contaminated areas, plan protection concepts, separate transport routes, and decontamination zones. For concrete demolition shears, tank cutters, and steel shears, protective hoods, drip mats, and clean separation surfaces are useful to protect the surroundings. Time-window concepts, dust control at transfer points, and floor protection mats further reduce impacts on operations and the environment.

Maintenance, care, and documentation

Regular inspections of lashing points, sideboards, stakes, and braking systems increase safety. Lashing straps, chains, and slings are checked for wear and replaced according to the manufacturer’s specifications. Loading decks remain clean, dry, and free of oil to ensure friction. For hydraulic power packs and splitters, documenting transport, operating hours, and inspection intervals is recommended. Checklists help with handovers between shifts. Notes in this section are general and non-binding.

• Assign unique IDs to slings and straps and record their inspection history
• Calibrate load cells, torque tools, and pressure gauges at defined intervals
• Document defects, near-miss events, and corrective actions in a centralized log

Distinction: transport vehicle and carrier machine

In day-to-day site operations, roles can blur: a forklift can transport and position, and an excavator can move attachments briefly. Nevertheless, the difference remains essential: the transport vehicle is designed for safe, compliant transport; the carrier machine for the working function. For logistics, this means: align load distribution, lashing concept, and routing to the respective transport vehicle and view the work system with concrete demolition shears, stone and concrete splitters, combi shears, Multi Cutters, steel shears, and tank cutters as a whole. Approval, insurance, and operator requirements typically differ between transport vehicles and carrier machines, which must be reflected in planning and documentation.
