SQ14SA5 14 t Crane on a Four-Axle Truck in Russia

A light-blue four-axle truck with a grey dropside body, and behind its cab a red BOB-LIFT SQ14SA5 telescopic crane with a raised control seat: four photos from our customer in Russia show the finished truck from both sides and from the rear, parked in a yard among brick buildings.

The finished truck

• Chassis and body. The cab is light blue with a bear decal on the door. The truck has two steering axles at the front and two axles at the rear. The grey dropside body has yellow reflective strips along both sides, and a spare wheel hangs under its rear end.
• Crane in transport position. The column stands directly behind the cab, and the five-section boom rests along the top of the body. The boom carries the BOB-LIFT and SQ14S markings.
• Raised control seat. A close-up from the cab side shows a control seat high on the column, reached by a ladder, with the hydraulic oil tank and a yellow hose run on the frame below it.
• Outriggers. Red outrigger beams sit under the crane base, and a second pair of red legs is fitted behind the rear axles.
• Site. The truck stands on a paved yard next to a brick workshop under a cloudy sky. No load is on the hook in any photo.

These are the customer's own photos. No lift weights, dates or comments came with them.

SQ14SA5 specifications

The SQ14SA5 is a 14 t telescopic boom truck-mounted crane with a maximum lifting moment of 35 t·m and five boom sections. Reach and load figures are read from the technical department's load chart drawing; the hydraulic figures come from the BOB-LIFT brochure.

Lifting moment is the load times its distance from the slewing centre. That is why the rated load drops as the boom reaches out. For example, the SQ14SA5 lifts 14,000 kg at 2.5 m but only 800 kg at 19.33 m. Outrigger span is the width between the outrigger feet when they are fully out. Set them on firm, level ground, such as concrete or compacted gravel, before each lift. For ground and outrigger rules, see the OSHA cranes and derricks standard.

The full 14,000 kg is rated at 2.5 m. At 9.2 m, about the far end of a body this long, the rating is 3,500 kg, and at the 19.33 m tip it is 800 kg.

The SQ14SA5 product page has the dimension drawing and the full specification.

Why a 14 t crane goes on a four-axle chassis

The crane alone weighs 5.1 t, and almost all of it sits just behind the cab. That is why a crane in this class is often built on a chassis with two front axles, as here. Three checks decide the build:

1. Front-axle load. Add the crane, the subframe and the oil tank, then check the combined front-axle rating before choosing the body length.
2. Space behind the cab. The SQ14SA5 needs about 1,300 mm of installation space, which comes off the body length.
3. Power take-off. The crane is specified for 75 L/min at 26 MPa, about 42 kW. The gearbox PTO and pump need to deliver that at a steady engine speed.

At full extension the main outriggers span 7.4 m. Rear legs like the ones on this truck support it when loads are slewed over the back of the body; plan lift positions so the ground under every foot is firm and level. How we plan the subframe and fit a crane to a customer chassis is on the mounting and shipping page. Other capacities are in the telescopic boom truck mounted crane range.

Checking a truck for the SQ14SA5

Before you order, check three things on your truck. They decide whether the SQ14SA5 fits it.

• Payload. The crane weighs 5,100 kg. Take this off the truck's payload, then plan the body and the loads you carry with what is left.
• Hydraulic power. The crane needs 75 L/min at 26 MPa, about 42 kW. The power take-off and pump on your truck must give at least this.
• Outrigger room. The outriggers span 2,260 to 7,400 mm. Make sure the frame has room for them, and that your job sites do too.

Send us the make, model and wheelbase of your truck through the contact page, and our team will check the fit.
