Claims (15)

1. A pipe spreader comprising:

a frame; and

a pair of mutually cooperating pipe engagement assemblies, coupled to the frame, for engaging a pipe;

each of the mutually cooperating pipe engagement assemblies comprises:

at least one spreader assembly, the at least one spreader assembly includes a spreader beam and an end manipulator coupled to the spreader beam,

wherein the at least one spreader assembly is arranged to be selectively removable from the pipe engagement assembly;

said spreader beam having at least one arm positioned in at least one channel formed on the frame such that the spreader beam is arranged to slide along the at least one channel;

wherein the spreader beam and the spreader assembly are arranged to slide in an orthogonal direction relative to a longitudinal axis of a pipe engageable by said pipe spreader.

2. The pipe spreader according to claim 1 , wherein each of the pipe engagement assemblies further comprises a support arm arranged to contact and support the pipe engageable by the pipe spreader as the pipe is lifted.

3. The pipe spreader according to claim 2 , wherein the support arm is arranged to exert a downward force on the pipe.

4. The pipe spreader according to claim 2 , wherein the support arm is spring loaded so as to exert a resilient downward force on the pipe.
