The UNIC URW-295 VO is the variable outrigger version of the URW-295 and URW-295-2 mini spider cranes, retaining all the benefits of the standard platform with the addition of variable, adjustable outriggers for operating around fixed obstacles on site. The adjustable outriggers reduce the working footprint of this already compact machine, making it ideal for extremely tight and small spaces. Variable slew and variable height limitation enable safe operation in defined zones, and the VO configuration is also available on Eco-295 battery models.
Key Features
- Independent variable outriggers — set each outrigger to any angle within its envelope to clear obstacles
- Variable slew limitation — define safe slew arcs around restricted areas with audible warnings on approach
- Variable height limitation — set boom height limits to avoid overhead obstructions
- Reduced working footprint — operate in spaces too tight for fixed outrigger geometry
- Full URW-295 capacity retained — 2.9t × 1.4m capacity unchanged from the standard platform
- Available on Eco-295 battery models — combine variable outriggers with zero-emission battery operation

UNIC Cranes | LOLER Compliant | Hire from WOLFF Onsite
This UNIC mini spider crane is supplied by WOLFF Onsite for hire across the UK. All cranes are LOLER-tested and supplied with a current Report of Thorough Examination. UNIC has been manufacturing mini spider cranes for over 50 years and is the original spider crane brand — the patented stability protection, intelligent voice warning system and computer-controlled moment limiter set the safety benchmark for compact lifting. Operator training, on-site delivery and full technical support are available — contact our team to discuss your project.
More About This Product
The UNIC URW-295 VO is the variable outrigger version of the URW-295 and URW-295-2 mini spider cranes. It retains all the benefits of the standard URW-295 platform, with the addition of variable, adjustable outriggers, enabling this mini crane to operate around fixed obstacles on site and adapt to the unique constraints of each project. The adjustable outriggers reduce the working footprint of this already compact mini machine, making it ideal for working in extremely tight and small spaces. Includes variable slew and variable height limitation for safe operation in defined zones, and is also available on Eco-295 battery models.
Suitable Applications
The URW-295 VO is specified where the working space is genuinely awkward — alongside columns, in corners, around scaffolds, or near sensitive equipment that must not be disturbed. Typical uses include glass lifting in atriums with columns, plant rooms with fixed obstacles, museum and gallery work where exhibits must not be approached, and confined urban lifts where standard outriggers cannot deploy to maximum on all sides.
How to Set Up and Operate the URW-295 VO
- Survey the working area, verify ground bearing capacity against the published point loadings and confirm overhead clearances are sufficient for the proposed boom geometry.
- Track the crane into position using the operator's seat or radio remote. Ensure the chassis is on firm, level ground or that load-spreader mats are deployed.
- Deploy the outriggers to the configuration required by the lift plan — set each outrigger angle and extension, ensuring stabiliser pads make full contact with the ground.
- Level the crane using the bubble level / auto-level system and verify all outrigger interlocks are engaged before luffing the boom.
- Configure the rope reeving (1-fall, 2-fall, 4-fall or 5/6-fall as applicable) to match the planned load and required rope length.
- Set any working area, slew or height limits required by the lift plan via the safe load indicator interface.
- Carry out a function test, confirm the moment limiter and voice warning system are operational, then lift to working position and complete the lift in accordance with the lift plan.
- On completion, return the boom to the stow position, retract outriggers and secure the crane for transit or overnight parking.
Warning:
Spider cranes must only be operated by CPCS / NPORS / equivalent-certified operators working to an approved lift plan. Never exceed the rated capacity at the relevant radius shown on the load chart. Power source: Petrol / Diesel / LPG / Electric / Battery (Eco-295).
Safety Information
- The crane must only be operated by competent, trained and certified operators familiar with this specific UNIC model.
- A documented lift plan, prepared by an Appointed Person, is required for every lifting operation under LOLER 1998.
- Ground conditions must be assessed against the manufacturer's point loadings — supplied on request — before each lift.
- Outriggers must be deployed to a configuration that supports the planned load at the planned radius; mixed-extension configurations require a competent rating check.
- Never operate the crane outside the rated load chart, override the safe load indicator, or carry loads with the boom in an unintended configuration.
- Carry out daily pre-use checks of hooks, wire ropes, hydraulics, safety devices and the moment limiter prior to first lift each shift.
Inspection and Maintenance
Spider cranes must be subject to a Thorough Examination by a Competent Person at least every 12 months under LOLER 1998, with additional 6-month examinations required where the crane is used to lift persons. Daily pre-use checks should cover wire rope condition, hook and shackle integrity, hydraulic system, outrigger pads, tracks, safety devices and the safe load indicator. All WOLFF Onsite hire cranes are supplied with a current Report of Thorough Examination and full service history. Defects identified in service must be reported immediately and the crane taken out of use until repaired.
Frequently Asked Questions
Q: Can the URW-295 VO be operated indoors?
Yes — the URW-295 VO is specifically designed for indoor and sensitive-environment lifting. It is fully battery powered with zero tailpipe emissions and low noise, making it suitable for hospitals, listed buildings, food processing plants and other indoor sites.
Q: Do I need a trained operator to use this crane?
Yes. All spider cranes must be operated by a competent, trained and certified operator (typically CPCS or NPORS certified). WOLFF Onsite can supply operated hire or arrange operator training as part of the package — please contact us for details.
Q: Is the URW-295 VO available for short-term and long-term hire?
Yes. WOLFF Onsite offers daily, weekly, monthly and project-length hire for the full UNIC URW range. Contact us with your project dates, lift plan and site address for a tailored quotation including delivery, off-load and operator if required.
Q: What are the point loadings I need to consider?
Spider crane point loadings vary with boom angle, radius and outrigger configuration, so they are supplied on a per-project basis. Provide your lift plan and proposed setup position and we will supply the relevant point loading data for ground bearing assessment.
