Telescopic boom truck cranes from 2 t to 20 t

A telescopic boom truck crane, often called a boom truck crane or stiff boom crane, lifts with a straight boom made of sections that slide out of each other. It gives a direct reach from the truck bed to the ground or a nearby site, and it is common in construction, logistics and municipal work.

BOB-LIFT currently builds telescopic boom truck mounted cranes in 11 capacity classes from 2 t to 20 t (metric tonnes): 2, 3.2, 4, 5, 6.3, 8, 10, 12, 14, 16 and 20 t. Seven classes come with two boom lengths, 18 configurations in all; the 5 t class, for example, comes as the SQ5SA3 and SQ5SA4. We have built truck mounted cranes in Xuzhou since 2003, and each crane is tested on our test bay before it ships. We supply the crane on its own for mounting on your truck.

If your truck body is short or you need the crane to fold away behind the cab, compare our knuckle boom truck mounted cranes.

Buying guide

How to choose a telescopic boom truck crane

Choose a boom truck crane by the load it must lift at your real working radius. Then check that your truck can carry the crane and drive its hydraulics. The five checks below use figures from our own load charts and drawings.

  1. 01Size it by the load at your working radius

    The capacity class is the most the crane lifts close to its column. The SQ14SA5 lifts 14,000 kg (30,800 lb) at 2.5 m, 3,500 kg at 9.2 m and 800 kg at its full 19.33 m (63 ft). Measure the horizontal distance from the crane column to where the load must land. That is your working radius, and the load chart shows what the crane lifts there. Our guide on how to read a crane load chart walks through it.

  2. 02Choose the number of boom sections for your reach

    Within one capacity class, more boom sections give more reach but less lift at the tip. The SQ5SA3 has three sections and reaches 8.68 m, where it still lifts 1,100 kg. The SQ5SA4 has four sections and reaches 11.79 m, but lifts 970 kg at 8.5 m and 600 kg at full reach. If none of your lifts go beyond 8.68 m, the SQ5SA3 is 300 kg lighter and lifts more at that distance. Choose the SQ5SA4 when you need the extra 3 m of reach.

  3. 03Check the truck before the crane

    The crane's own weight ranges from 950 kg for the SQ2SA3 to 7,300 kg for the SQ20SA5, and it must fit within your truck's remaining payload. The crane also needs 650 mm to 1,400 mm of mounting space between the cab and the body, depending on the model. Send us the chassis model, wheelbase and gross vehicle weight, and we will confirm the mounting before you order. See how we handle truck mounting and export.

  4. 04Match the hydraulic supply

    Each crane is driven by the truck's power take-off (PTO) and hydraulic pump. The recommended supply ranges from 8 kW and 20 L/min (SQ2SA3) to 55 kW and a dual 80 + 63 L/min circuit (SQ20SA5). Check that your PTO and pump can deliver this. The specification table on every product page gives that model's figures.

  5. 05Check the slewing range and boom angle

    Every current telescopic model is rated for 360° of rotation, so you can work on either side of the truck and behind it. The boom raises to 75°, and the crane lifts more as the boom gets steeper because the radius gets shorter. With its boom fully extended, our 10 ton boom truck crane, the SQ10SA4, lifts 1,050 kg at 15.5 m when the boom is horizontal, 1,850 kg at 10 m when it is raised to 50°, and 3,400 kg at 4.2 m when it is raised to 75°. Plan each lift with the boom angle you can actually use on site.

Frequently asked questions

Is a boom truck the same as a telescopic truck mounted crane?

In most markets, yes. "Boom truck" usually means a truck with a hydraulic crane that has a straight, telescoping boom, which is what this page lists. Some buyers also call a knuckle boom crane a boom truck, so check the boom type on each product page. Bucket trucks for working at height are a different machine; see our aerial work platforms.

What sizes do BOB-LIFT telescopic boom truck cranes come in?

There are 18 configurations in 11 capacity classes from 2 t to 20 t. Maximum lifting moment (load × distance) ranges from 4.2 t·m (SQ2SA3) to 50 t·m (SQ20SA5). Maximum reach ranges from 8.2 m (SQ2SA3) to 22.3 m (SQ16SA5), or about 27 ft to 73 ft.

How much can a boom truck crane lift?

Our telescopic boom truck cranes lift from 2,000 kg to 20,000 kg (about 4,400 lb to 44,000 lb) close to the column. Capacity falls as the boom reaches out: the SQ20SA5 lifts 20,000 kg at 2.5 m and 1,500 kg at its full 22 m. Always check the load chart at your working radius.

Should I choose a telescopic boom or a knuckle boom crane?

A telescopic boom extends in a straight line and suits long, direct lifts from the truck to the ground. A knuckle boom folds compactly behind the cab and can reach over and down past obstacles. At 10 t the two types are similar in weight and lift: the telescopic SQ10SA4 weighs 3,800 kg and lifts 1,050 kg at 15.5 m. The knuckle boom SQ10ZA6 weighs 3,700 kg and lifts 1,150 kg at 14.68 m. Choose by your truck, your site and the jobs you repeat most. Compare our knuckle boom truck mounted cranes.

What does a model code such as SQ14SA5 mean?

In SQ14SA5, SQ marks a truck mounted crane, 14 is its 14 t capacity class, S means telescopic (straight) boom and A5 means five boom sections: the main boom and four hydraulic extensions. The knuckle boom models use Z in the same place, as in SQ10ZA6.

How do I order a telescopic boom truck crane, and what warranty is included?

You can order a single unit. Tell us your truck, your typical loads and working distances. We confirm the model and its configuration with you before production. Each crane comes with a 12-month warranty. Send us your inquiry.
