UNIC URW-295 VO Variable Outrigger Mini Spider Crane

Model URW-295 VO | 2.9t × 1.4m Max Capacity | Variable Adjustable Outriggers | Slew and Height Limitation | Built on URW-295 / URW-295-2 Platform | Optimised for Obstacles On Site

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.

Technical Specifications

Specifications above are taken from the UNIC manufacturer's spec sheet at standard configuration. Variants with electric, LPG or other options may differ slightly — full rated capacity charts supplied with each hire.

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

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

1. Survey the working area, verify ground bearing capacity against the published point loadings and confirm overhead clearances are sufficient for the proposed boom geometry.
2. 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.
3. 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.
4. Level the crane using the bubble level / auto-level system and verify all outrigger interlocks are engaged before luffing the boom.
5. 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.
6. Set any working area, slew or height limits required by the lift plan via the safe load indicator interface.
7. 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.
8. 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.
