UNIC URW-1006+ Mini Spider Crane

Model URW-1006+ | 10.0t × 3.0m — World’s Largest Capacity Mini Crane | 2.0m Width | 30.7m Lift Height with Extension Jib | Pick & Carry Capacity | Kubota Stage V Diesel + Optional 400V

The UNIC URW-1006+ offers an unrivalled 10 tonnes of lifting power, making it the world’s largest-capacity mini spider crane. Boasting up to 30.7 metres of lifting height and a 24.3 metre working radius, this 10-tonne spider crane features a newly revised load chart and has a unique pick-and-carry function, enabling it to travel with loads up to 1.5 tonnes. The URW-1006+ outriggers can be configured to provide maximum stability when lifting on uneven surfaces thanks to their full interlocking safety system, and an innovative high-resolution colour LCD safe load indicator acts as an integrated safety feature to prevent operation outside the safe working range.

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

• World’s largest mini spider crane — 10 tonnes lifting capacity — class-leading
• 30.7m maximum hook height — with second-stage hydraulic fly jib
• Pick & carry up to 1.5 tonnes — travel across site without setting down
• Full interlocking outriggers — configurable for uneven surfaces with safety lockout
• Standard 1000kg hydraulic fly jib — single-part-line — included as standard equipment
• Radio remote with digital feedback — shows safe load, actual load, radius and boom length
• Kubota Stage V diesel — with optional 400V mains electric dual power, zero length increase

Suitable Applications

The URW-1006+ operates where conventional cranes can’t deploy but the lift demands serious capacity — major plant placement, structural steel erection, communications and broadcast tower work, energy infrastructure, and large-scale internal fit-out. The pick-and-carry function and 30.7m hook height make it uniquely capable on confined major construction projects where mobile crane access is impossible.

How to Set Up and Operate the URW-1006+

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: Stage V Diesel + Optional 400V Electric.

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.
