Sennebogen launches new telecrawler

German manufacturer Sennebogen has added another model to its range of telescopic crawler cranes: the 80-tonne capacity 683 E.

The mid-sized machine fits into the gap between the existing 673 E and the 6103 E and is the ninth model in the series.

According to Sennebogen the 683 E, with its heavy-duty boom and powerful travel and winch motors, has been built for a wide range of applications The crane is also suitable for pick-and-carry work and lifting operations on inclines of up to four degrees.

The 683 E is powered by a 186 kW Cummins engine with Stage V exhaust gas treatment. The main and auxiliary winches are driven by a high-pressure piston engine which provides a tractive force of 72 kN each and speeds of up to 120 m/min.

The individually configurable equipment can be supplemented by a range of options including a programmable working range limiter plus safety and low-temperature packages. This, Sennebogen believes, will particularly appeal to users in specialised civil engineering and hydraulic engineering sectors.

The crane has a four-section full power main boom with a length of 42 m. Multicylinder technology means the maintenance-free boom provides variable telescoping with force-locking. The crane’s reach can be further extended to up to 57 m with an optional double folding jib (that can be angled).

The 683 E’s undercarriage has a maximum track width of 4.2 m. This can be reduced symmetrically or asymmetrically to 2.68 m with the load charts being automatically adapted to the respective track width.

Using a radio remote control the 6103 E can unload itself from a truck and is completely self-assembling. With crawler tracks attached it has a transport width of only 3.5 m. After disassembly of the crawler, the transport weight is reduced by almost 20 t and the transport width contracts to 3.0 m.  

The crane comes as standard with 800 mm triple grouser shoes designed to provide stability while keeping floor pressure at a minimum. 

The crane has Sennebogen’s Maxcab cabin that offers up to 20 degrees of tilt. If required, a hydraulically elevating cab that can be tilted 30 degrees at an eye level of 5.55 m, can be supplied. Sennebogen says the cabin has large windows for maximum visibility.

The crane can also be operated from outside the cabin via a radio remote control. Cameras and a large monitor are designed to extend the operator's field of vision to the rear and right side and can also be used to monitor the winches.

The electric dual-axis control system features joystick control buttons for optional attachments and the graphically displayed load moment limiter. The system provides an audio-visual warning and locks the control lever when the load limits are reached or exceeded. The Sencon control system provides important diagnostics as well as valuable data on payloads, boom angle, boom length, and radius. 

Sennebogen says the 683 E has been designed to be easy to service, with an easy-to-access central lubrication point for the boom base axle, luffing cylinder, and slewing ring and clearly identified components.
