UNIC URW-295-110V Plug-In Mini Spider Crane

Model URW-295-110V | 2.9t × 1.4m Max Capacity | 600mm Width | 8.8m Lift Height | 110V Plug-In + Petrol or Diesel | Zero Length Increase with Electric

With the introduction of 110V plug-in operation, the UNIC URW-295-110V takes flexibility and safety to a new level. Operators can simply “plug and lift” directly from a standard 110V site supply, making set-up faster, safer and more convenient. Built on the proven URW-295 platform with an 8.65m boom reaching up to 8.8m high, plus an optional fly jib for added reach, the URW-295-110V combines robust engineering with the clean, quiet operation required for indoor projects and low-emission zones. Available with either a petrol or diesel engine alongside the 110V electric option.

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

• 110V plug-and-lift operation — powers the crane directly from a standard 110V UK site supply
• Zero length increase with electric option — no added footprint compared to the engine-only variant
• Dual power source — switch between engine and 110V mains for indoor / outdoor versatility
• Clean and quiet for indoor lifting — ideal for low-emission zones, occupied buildings and listed sites
• Almost 3 tonnes through a doorway — 2.9t at 1.4m radius from a machine just 600mm wide
• Variable outrigger and fly jib options — tailor the footprint and reach to each project

Suitable Applications

The URW-295-110V is the right choice when site rules require a 110V power source or when the client wants the simplicity of a plug-in lift on top of engine power. Frequently specified for tier-one contractor sites, occupied building refurbishments, low-emission zones, and any indoor lift where extension leads and engine fumes are unwelcome. Maintains the full 2.9t capacity and 8.8m reach of the standard URW-295.

How to Set Up and Operate the URW-295-110V

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 + 110V 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.
