Telehandlers

A telehandler, or telescopic handler, is a lifting machine with a telescopic boom mounted on a four-wheel-drive chassis. It combines the lifting height of a small crane with the manoeuvrability of a forklift and the versatility of a loader. With forks it places pallets of bricks on a scaffold; with a bucket it loads aggregates; with a winch or jib it lifts and positions loads like a crane; with a work platform it lifts people. On building sites and farms, it is often the most used machine of all.

Brief History of Telehandlers

Machines with telescopic booms for material handling appeared in the 1970s. The best-known milestone is the JCB Loadall, launched in 1977, which popularised the concept of a rough-terrain telescopic handler with a boom mounted low at the rear of the chassis. The machine quickly became a standard on British and European building sites, and later spread to agriculture, where it replaced much tractor-loader work.

Italian and French manufacturers such as Merlo, Manitou and Dieci developed the category further, adding stabilisers, heavier capacities and, in the 1990s and 2000s, the rotating telehandler, which mounts the boom on a slewing turret and bridges the gap between telehandlers and mobile cranes. In North America, telehandlers became a mainstay of rental fleets, where they are often called “reach forklifts”.

How a Telehandler Works

Chassis: a rigid frame with four-wheel drive and, usually, selectable steering modes: front-wheel steer, four-wheel (round) steer and crab steer for moving sideways alongside walls.
Telescopic boom: two or more sections extended hydraulically, pivoting at the rear of the machine. Low-mounted booms keep the centre of gravity down and leave good visibility to the right.
Carriage and quick-hitch: at the boom tip, a carriage accepts forks, buckets and other attachments.
Stabilisers: on larger machines, front outriggers increase capacity at height and reach.
Frame levelling: allows the chassis to be levelled on uneven ground before lifting.
Load management system: electronic monitoring of the load moment that warns the operator and blocks unsafe movements as the load approaches the stability limit.

The key figures are maximum lift capacity, maximum lift height, maximum forward reach and, most important in practice, the capacity at a given height and reach, read from the load chart.

Types of Telehandlers

Compact Telehandlers

Machines with lift heights of about 4 to 7 metres and capacities of about 2 to 3 tonnes, often narrow and low enough to work in barns, warehouses and renovation sites.

Standard Construction Telehandlers

The classic building-site machine, lifting about 3 to 4 tonnes to heights of around 12 to 18 metres. Used for materials on scaffolds, roofs and floors.

High-Capacity Telehandlers

Heavy machines lifting 5 to 10 tonnes or more, used in steel erection, heavy industry, quarries and recycling.

Agricultural Telehandlers

Built for loading, stacking bales and handling feed and grain, with higher travel speeds, more powerful hydraulics and strong loader performance.

Rotating Telehandlers

The boom is mounted on a turret that rotates continuously, and the machine works on four outriggers. With forks, a winch or a man basket, a rotating telehandler can act as a forklift, a crane and an aerial work platform, with lift heights beyond 30 metres on the largest models.

Load Charts and Stability

A telehandler’s rated capacity applies only close to the machine. As the boom extends, the load moves further from the front axle and the capacity falls. The load chart, displayed in the cab, shows what the machine can lift at each combination of height and reach, with and without stabilisers and for each attachment. Modern machines have load management systems that read boom angle, extension and load and limit movements automatically, as required by European standard EN 15000 for longitudinal load moment control.

Size Classes

Class	Typical lift capacity	Typical lift height
Compact	about 2 to 3 t	about 4 to 7 m
Standard construction	about 3 to 4 t	about 12 to 18 m
High capacity	about 5 to 10 t and more	about 9 to 18 m
Rotating	about 4 to 7 t	about 16 to 35 m and more

Figures are indicative.

Attachments

Pallet forks and fork positioners, buckets of all sizes, crane jibs and winches, lifting hooks, grabs and bale handlers, sweepers, concrete buckets and, on certified machines, work platforms for people. Many telehandlers recognise the attachment automatically and select the right load chart.

Main Manufacturers

JCB, the inventor of the Loadall and one of the market leaders.
Manitou, a French pioneer with construction, agriculture and rotating models.
Merlo, the Italian specialist in telehandlers and rotating machines.
Dieci and Magni TH (rotating telehandlers), also from Italy.
JLG (Oshkosh) and Genie (Terex), strong in North American rental fleets.
Bobcat, Caterpillar, CLAAS, New Holland, Kramer and Faresin.

Main Uses

Building sites: bricks, blocks, roof trusses, formwork, scaffolding materials.
Agriculture: bales, feed, grain, manure and general loading.
Industry and logistics: loading trucks and handling heavy components.
Recycling and waste handling.
Events, rental and facility management.
With rotating models: light crane work and access at height.

Choosing a Telehandler

The right telehandler is chosen from the load chart, not from the headline figures. A machine rated at 4 tonnes and 17 metres will not lift 4 tonnes at 17 metres: at full height and reach the capacity is much lower. Start from the heaviest load and the highest and furthest point where it must be placed, and check the chart for that combination with the attachment that will actually be used.

Other factors include the machine’s height and width for access to buildings and barns, turning radius, travel speed if the machine moves between sites or fields, cab comfort for long shifts, and the availability of attachments. For rental fleets, simplicity, robustness and common parts across the range often matter more than top performance.

Safety

Most telehandler accidents involve tipping, loads falling and people being struck. Good practice includes:

Always checking the load chart for the attachment, height and reach being used.
Levelling the frame and using stabilisers where required.
Carrying loads with the boom retracted and low.
Never exceeding the rated capacity or overriding the load management system.
Lifting people only with certified platforms and machines approved for that use.
Keeping pedestrians clear of the working area and watching for overhead power lines.

Trends and Technology

Electric telehandlers, with the first battery-electric models now on the market for indoor work, farms and zero-emission sites.
Advanced load management with real-time stability calculation and automatic attachment recognition.
Camera and radar systems to improve rear and right-side visibility.
Telematics for rental fleets.
Hybrid and alternative fuels for agricultural machines working long hours.

Key Terms

Lift height: the maximum height the forks or attachment can reach.
Forward reach: how far the boom can extend in front of the machine.
Load chart: the diagram that shows the permitted load at each combination of height and reach.
Stabilisers: legs lowered at the front to increase stability on high-capacity machines.
Frame levelling: a system that tilts the chassis to keep the boom vertical on uneven ground.
Crab steer: all four wheels steer in the same direction so the machine moves sideways.
Load moment indicator: a warning or cut-out system that prevents the machine from tipping forwards.

Frequently Asked Questions

Telehandler or forklift? A forklift is designed for flat, paved ground and vertical stacking. A telehandler works on rough ground and places loads forwards and upwards, over obstacles.

Can a telehandler be used as a crane? Yes, with a crane jib or winch and when permitted by the manufacturer and local regulations. Rotating telehandlers are often used for light crane work.

What is a rotating telehandler? A telehandler whose boom is mounted on a rotating turret, allowing it to lift and place loads through 360 degrees without moving the machine.

Do you need a licence to drive a telehandler? In most countries operators need specific training and certification for telehandlers. Requirements vary by country, so check the local rules before work starts.

What is the difference between a telehandler and a loader? A loader digs and carries loose material close to the ground, while a telehandler is designed to lift and place loads at height and reach.

Can a telehandler carry people? Only with a work platform attachment approved by the manufacturer and in line with local regulations. Many modern machines recognise the platform and limit their movements automatically when it is fitted.

Why do telehandlers have different steering modes? Two-wheel steer suits travel on roads, four-wheel steer gives a tight turning circle in confined sites and crab steer moves the machine sideways, which helps when placing loads close to walls.
