TRIANGULAR LOOP HANDLE WITH THREE GRIPS
A handle for a wheelbarrow is provided. The handle has a body with a handle portion and a coupling device. The handle portion has three grips. The handle body forms a loop having arcuate transition portions between the grips. The grips are angled relative to the wheelbarrow frame assembly handle shafts so as to provide the user with a comfortable grip during both transport of the wheelbarrow as well as during a lifting motion of the handles.
