Light Crane Systems

Light aluminium cranes for lifting points where no fixed crane is installed. The foldable gantry breaks down to fit a commercial vehicle and is reassembled without special tools, and the light gantry on legs carries up to 2,000 kg on its short beams. Aluminium does not rust, so they suit outdoor work, food processing and water and sewage sites.

Foldable Aluminium Gantry

250–1000 kg
Manual

A foldable aluminium gantry crane is a portable crane that folds or breaks down small enough to fit in a van, and is set up wherever a load needs lifting and there is no fixed lifting infrastructure. It suits field service and maintenance teams, workshops and plants that need a temporary lifting point they can move between workstations. Assembly uses removable pins and fixed joints, with no special tools. On most models the beam height and the span between the legs adjust in fixed steps, so the crane can pass through doorways, work under low ceilings or stand over a wide machine. A push trolley carrying the hoist runs along the beam. The legs stand on locking swivel castors, so the crane can be moved when empty and locked in place before lifting. Most models must not be moved while carrying a load unless the model is specifically rated for it. Aluminium does not rust, so the crane also suits outdoor work, food processing and water and wastewater facilities. Typical uses: lifting motors, pumps and mechanical equipment at customer sites, lifting equipment out of shafts and manholes, and temporary lifting on production lines. The model table lists the lifting capacity, height range, span and dead weight for each model.

PG2

Lightweight Aluminium Gantry Crane

250–2000 kg
Manual

The PG2 lightweight aluminium gantry crane stands on two legs and is used for lifting where no fixed crane is installed. The structure is aluminium alloy, so it is relatively light to carry and assemble. Lifting capacity depends on beam length: up to 2,000 kg on the short beams, 2,500 to 3,920 mm, and up to 250 kg on a 9,000 mm beam. Beam lengths run from 2,500 to 9,000 mm, crane weight from 166 to 275 kg, and the weight of a single leg from 68 to 93 kg. The legs come in several builds, designated S, M, I and T. The model table lists the beam length, lifting capacity and weight of each model.

Frequently asked questions

What we get asked about Light Crane Systems

What is the lifting capacity of an aluminium gantry crane?

In the series on this site, the foldable gantry carries 250 to 1,000 kg, and the light gantry on legs carries up to 2,000 kg on its short beams and up to 250 kg on a 9 metre beam.

Can a portable gantry crane be moved while it carries a load?

On most models, no. The wheels are for moving the crane when it is empty and locking it in place before lifting, unless the model is explicitly approved for moving under load.

Can an aluminium crane be used outdoors?

Yes. Aluminium does not rust, so the crane also suits outdoor work, food processing and water and sewage sites.

Does a portable gantry crane need a certified inspector's examination?

Yes. Section 79 of the Safety at Work Ordinance lists a crane in the definition of a lifting machine, so it is examined by a certified inspector at least once every 14 months, under section 81.

EOT Cranes (Electric Overhead Travelling Cranes)

An overhead travelling crane is installed at the top of the building and travels along a fixed runway, covering the whole hall while leaving the floor clear. The bridge travels the length of the hall, the hoist travels across the bridge and the hook raises and lowers, so the load can reach any point under the crane. Overhead cranes are used in manufacturing plants, warehouses, workshops and maintenance halls. Overhead cranes differ in two main ways: Runway mounting Top running crane: the bridge travels on rails mounted on top of the runway beams, which are supported on the building columns or on concrete corbels. This configuration suits heavy loads and wide spans. Underslung crane: the bridge hangs from the roof structure and runs on the lower flange of the runway beams. This configuration suits buildings with no room for columns, and lets the hook get closer to the side walls. Number of girders Single girder: one girder with the hoist running on its lower flange. Lighter construction and quicker to install, suited to light and medium loads. Double girder: two parallel girders with a hoist trolley running on top of them. The hook rises up between the girders, giving more lifting height, and the structure suits heavy loads and intensive duty. The right crane depends on lifting capacity, hall width, available headroom and the existing structure. The model pages list the technical data for each type. The crane moves along three axes, down the length of the building, across the bridge and vertically, and covers the entire floor area without forklifts and without temporary rigging. The first decision is the mounting method. A top running crane travels on rails carried by columns and uses almost the full height of the building, which suits heavy loads and wide spans. An underslung crane hangs from the roof structure, and suits cases where columns cannot be added or where the production floor has to stay clear, at the cost of a shorter span. The second decision is the number of girders. A single girder is lighter, less expensive and puts less load into the structure. A double girder carries far heavier loads and also gives more hook height in the same building, because the hook rises between the girders rather than below them. The third decision is the operating environment. A bridge crane is built around its hoist unit and electrical system, so it can be specified for the environment it will work in. Alongside the standard industrial build we supply versions for ATEX classified areas, for marine and coastal installations, for dusty and high humidity conditions and for aggressive chemical environments. The specification is fixed at the design stage rather than retrofitted, so the environment should be defined in your first enquiry. We supply 129 configurations across three series: single girder from 2 to 12.5 tonnes over spans of 10.5 to 31.5 metres, double girder from 5 to 50 tonnes over spans of 13.5 to 31.5 metres, and underslung from 2 to 10 tonnes over spans of 6 to 20 metres. Standard lifting height is 9 metres and the duty rating is A5 to FEM 2M. Every crane is engineered to your building dimensions, your loads and your operating environment rather than selected from a catalogue. We carry out the site survey, the design, the installation and the commissioning, and stay with the crane through routine maintenance for its working life.

Jib Cranes

Jib cranes for workstations and machine tending, from the BRIMA catalogue. Six series: four with manual slew from 80 to 1,000 kg on arms of 3 to 7 m, and two with powered slew from 1,000 to 6,300 kg on arms of 5 to 10 m. Each mounts on its own column or on a wall, and slew runs from 180 to 360 degrees depending on the model. The 95 configurations the catalogue offers are set out in each series table, which gives, for every rating, the arm lengths it is sold in.

Wire Rope Hoists

A wire rope hoist is an electric hoist in which a steel wire rope winds onto a drum, driven by an electric motor to raise and lower the load. Wire rope hoists suit heavier loads, greater lifting heights and more intensive duty than chain hoists, which makes them the usual choice for overhead cranes, gantry cranes and lifting systems that work full shifts. The hoist is mounted to suit the crane: on a trolley running on the lower flange of the beam in a single girder crane, on a crab running on rails above the two girders in a double girder crane, or fixed on a base. For buildings with limited headroom there are low headroom versions, where the hoist sits tight against the beam and leaves more height under the hook. Most hoists have two lifting speeds or inverter speed control, for fast travel between points and gentle placing of the load. Upper and lower limit switches restrict hook travel, and overload protection stops the lift when the load exceeds the rated capacity. Each hoist's duty classification sets the operating hours and starts it is designed for, and should be chosen to match the work in the plant. The model pages list the lifting capacity, lifting height, working speeds and duty classification of each hoist.
