Established in 1952, Sennebogen has been manufacturing telescopic crawler cranes for more than 30 years, and it has successfully established this flexible crane concept in international markets.
With its load capacity of 80t and 42m of main boom, the Sennebogen 683 E is the ninth model in the series and fits perfectly into the gap between the existing 673 E and the 6103 E. It boasts impressive flexibility and a robust design that qualifies it for a wide range of applications and uses.
According to National Sales Manager Michael Cawston of Pace Cranes, the National Distributor for Sennebogen, the 683 E is well suited for a wide range of applications – with its heavy-duty Full Power boom and its powerful travel and winch motors. Sennebogen has updated the operating systems, assembly and disassembly process and transport configurations, in addition to the improved capacities and capabilities from the original D series crane.
“The 683 E is well-suited for building and below ground construction, bridge construction, pile driving during sheet pile installation, and as an agile auxiliary service crane,” Michael said.
“With its particularly robust design, it demonstrates its strength during heavy-duty use on rough construction sites, where it easily handles pick-and-carry tasks as well as lifting operations on a 4-degree incline.
“We have a large population of Sennebogens locally and customers always comment on how strong and well-engineered they are, and with the amount of infrastructure projects planned for the next decade or so, we are seeing increased demand for these larger capacity machines,” he said.
The 80t tele crane 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 considerable tractive force of 72 kN each and cable speeds of up to 120m/min. The individually configurable equipment can be supplemented by a wide range of attachments, options and additional features such as a programmable working range limiter and safety and low-temperature packages, thus appealing to users in specialised civil engineering and hydraulic engineering sectors, among others.
Flexible on the ground and at heights:
The 4-section Full Power-Boom, which can telescope to a length of 42m in the standard configuration, offers a decisive time advantage, especially in complex operations with changing boom lengths. Thanks to multi-cylinder technology, the maintenance-free boom control system provides variable telescoping and is always force-locking. This means that any desired boom length can be reached quickly and easily, and the best payloads are always achieved automatically. As an option, the reach can be further extended to up to 57m with a double folding jib that can be angled, making it particularly attractive for structural engineering. Operation is simple and intuitive via joystick movement.
The telescopic crawler undercarriage of the 683 E has a maximum track width of 4.2m. Depending on requirements, this can be reduced symmetrically or asymmetrically to as little as 2.68m, with the load charts being automatically adapted to the respective track width. Time-consuming positioning of the machine can be eliminated thanks to the robust design of the undercarriage, which is particularly beneficial when working on inclines and for pick-and-carry tasks. The 80-tonner not only boasts impressive load values at inclinations of up to 4 degrees but can even travel with 100 per cent of the specified load on the hook. The standard 800mm triple grouser shoes installed provide a high degree of stability while reducing floor pressure to a minimum.
The 683 E can unload itself from a truck and with the aid of the radio remote control it is completely self-assembling. With crawler tracks attached, it has a transport width of only 3.5m. After simple disassembly of the crawler, not only is the transport weight reduced by almost 20t: the transport width also contracts to 3m.
In the comfortable Maxcab cabin, machine operators appreciate the ergonomic advantages of what Sennenbogen says is a particularly spacious cab. For a comfortable view of even distant loads, the cab has a possible standard tilt of 20 degrees.
Optionally, the crane can also be equipped with a hydraulically elevating cab that can be tilted 30 degrees at an eye level of 5.55m. Large-area window elements provide an optimal view of the entire safety and work area. In addition, the machine can be operated from outside the cabin via a radio remote control. Cameras and a large monitor 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 intuitive Sencon control system provides important diagnostics as well as valuable data on payloads, boom angle, boom length and radius, thus supporting the operator in his work with the machine – for maximum availability.
The Sennebogen 683 E also proves to be highly advantageous in terms of service friendliness. A central lubrication point for the boom base axle, luffing cylinder and slewing ring greatly reduces operator maintenance. Optimum access to the service points and clear identification of the components also saves valuable time in daily operation.
The Sennebogen 6103 E, 100t capacity telescopic crawler, is the ‘top of the range’ model and impresses with 100t capacity, long reach and flexibility.
With its current product portfolio of telescopic cranes from 16t to 130t load capacity, Sennebogen covers a wide range of applications, where the telescopic crawler cranes in particular offer many advantages when lifting, moving and positioning large loads. The Sennebogen 6103 E is a telescopic crawler with a load capacity of 100t and a maximum boom length of up to 62m, specially designed for demanding Pick and Carry applications.
The 6103 E is equipped with a 186 kW diesel engine of emissions stage V, which also hydraulically drives the powerful crawler drive of the 100t machine as well as main and auxiliary winches with 100 kN tractive force each – while also allowing cable speeds of 125m/min. Thanks to a wide range of equipment solutions, the machine can also be configured to meet a variety of customer-specific requirements in special civil engineering or hydraulic engineering, for example with working area limitation, safety and low-temperature packages or for operation with organic oils.
The 5-section pin boom of the new 6103 E has a maximum length of 46.8m for the driver in standard configuration. The reach can be optionally optimised up to 62m with the fly jib and extension. The boom system thus enables comfortable working heights of up to 50m. Operation is carried out simply and intuitively via joystick movement.
Like all Sennebogen telescopic crawler cranes, the 100t machine also allows you to work on rough terrain. Thanks to the robust, telescoping crawler undercarriage with a maximum track width of 4.2m, there is no need for time-consuming positioning or supporting the machine.
The crawler undercarriage is also stable and secure during crane operation. The extremely robust design of the entire machine, as well as the boom, is particularly noticeable when working at inclines of up to four degrees and with high load capacities. The 6103 E sets an impressive standard in its performance class here. As a Pick and Carry crane, the telescopic crawler crane can also be moved with up to 100 per cent load on the hook and thus offers a wide range of applications, particularly in prefabricated part and component assembly and on large construction sites.
In addition to the tried-and-tested equipment features, the spacious Maxcab offers operators even more options for making every-day work particularly comfortable and safe. The telescopic crane has a cab that can tilt 20 degrees as standard. As an option, the cab can be hydraulically elevated to an eye level of 5.6m. Large-scale window elements and the tried-and-tested access area with sliding door leave nothing to be desired and provide an optimal workplace for the driver. There is also the option of operating the crane from outside the cab via radio remote control, which offers added precision and safety for operators and crew in many applications.
For contractors and rental companies alike, transport costs and set-up times are key criteria for efficient crane use. The new Sennebogen 6103 E telescopic crawler crane offers two major advantages here.
Additionally, the machine can be transported completely in one piece. For this, only the ballast must be removed to achieve a transport weight of around 61t and a width of 3.48m.
The crane weighs less than 40t and is therefore even easier to transport by low loader, when the crawler tracks are removed beforehand. The highlight with the 6103 E telescopic crawler crane is that all assembly steps can be carried out by the machine itself. Auxiliary cranes are not required thanks to the Sennebogen self-assembly system.
