Hydraulic spreader bars, specially designed for direct pipe contact
The ELiTE E-HYD-SB-15 hydraulic spreader bar
(Hydraulic Spreader Bar with a SWL of 15000kg)
Suitable for any crane type
A new state-of-the-art hydraulic spreader bar concept for any crane type application. The characteristics of some concrete coating do not allow for a safe pipe lift when utilising vacuum pipe lifters regardless of vacuum sealing types available.
The ELiTE E-HYD-SB-15
This unit is engineered to harmonise as lifting attachment with suitably sized cranes (single and double hooked). This particular “below the hook” material handling tool is electrically powered by the customers power supply and hydraulically driven via its own complete hydraulic power system.

Many traditional hydraulic spreader bars are manufactured to suit one or two particular pipe lengths only. The ELiTE E-HYD-SB-15 is engineered for maximum pipe length flexibility and handles numerous pipe lengths.
Integrated telescope arms (four) “2 x active and 2 x stationary” allow the ELiTE E-HYD-SB-15 to lift pipes from 6000mm up to 12900mm. The inner “active” telescope arms (penetrating the pipes inner) are driven by 2 hydraulic cylinders each of which have an individual locking force (load hold) of 6000kg. The locking force of 6000kg is required to eliminate the possibility of a pipe pushing the hydraulic cylinders/ pipe pins open during an uneven pipe lift (i.e. uneven ground level) or swinging of the pipe during a lifting maneuvers.
The outer “stationary” telescope arms are
pre set by the operator to lift a particular range
of pipe lengths before the lifting application is started.
If a pipe of lets say, 10000mm is to be lifted, a pre setting or positioning of 9 – 10 will be carried out. This is possible by lining up both telescopes to coincide with clearly marked templates visible on the outer sides of the stationary telescope arm, This pre setting is completed in a matter of minutes. In order that pipe lifts are safe and efficient, both hydraulic cylinders operate simultaneously.
The ELiTE E-HYD-SB-15 is equipped with its own “onboard” hydraulic system which includes a large oil reservoir and oil bath-catch. Electrical power is delivered from the crane system to the hydraulic system via a heavy duty onboard spring- loaded cable drum with industrial plug/ socket. All onboard values are pre set during Schoenbeck FAT QM procedures but can naturally be adjusted easily onsite if needed.
Pipe protection
When lifting a pipe with clamps or other methods of internal pipe contact, it is naturally of great importance not to damage the pipes structure, pipe beveled ends or internal pipe lining. The pins (pipe carrying arms) are equipped with purpose manufactured durable rubber padding situated at both lifting ends of the tool. The top layer is designed to make contact with the pipes inner (upper) internal area and carry the pipe without causing damage to pipe inner/ welds or lining. A further rubber protection of the same material has been incorporated and situated at the spear tip ends of the pins (pipe carrying arms). This protection prevents damage to the pipe bevel/ pipe ends in the unlikely event that the operator collides during pipe alignment maneuvers’. Finally, red bronze plate padding has been incorporated at possible pipe contact points. Additionally at the underside of the main body we have installed 2 rubber protection buffers for the unlikely event that an operator should lower the machine too far and rest on the outer pipe surface.
It is an absolute necessity that all manufactured lifting and handling tools are sufficiently equipped with suitable warning signals which are foreseen to protect all concerned during, before and after a lifting operation. This signal should be clearly visible, not only for operator but also for the surrounding environment. The ELiTE E-HYD-SB-15 is fitted with 2 flashing LED green lights at either end the outer arms. These indicators only then flash (constant) if the pipe is perfectly and safely seated on the pipe intruding pins. If the operator purposely or accidently activates the command to open /retract the pipe pins, a siren is automatically active.
