A modular cable bridging assembly has a cable protector with side ramps, and a series of channels extending between its ends to receive cables or the like. End connectors enable the cable protectors to be attached together in series to any desired length. Secondary ramps can be removably attached over each side ramp of a cable protector for handicapped access. Each secondary ramp has a base extending laterally beyond the side ramp, and an upper surface extending over the side ramp having a slope that is less than that of the underlying side ramp. A secondary ramp connector is used to removably attach the secondary ramp to the cable protector. Edge rails can be removably attached to the secondary ramps for safety and structural rigidity.

The present invention is directed to a brake shoe adapted for use in a braking mechanism that comprises a support member and a substantially metal free brake pad disposed on the support member. The brake pad may be composed of polymerized urethane as a major constituent thereof. More particularly, the brake pad may be composed of a mixture including urethane, a urethane reactant and a urethane curing agent. The durometer hardness of the brake pad may be between 80 and 95 on the A-scale. The support member may include a connector and a base plate, and the brake pad may be formed as an integral one-piece molded construction with the base plate being embedded in the brake pad. The brake pad may have a contact surface that is contoured so that the brake pad has varying thickness to differentially contact a moving surface. The present invention also provides a caliper-type braking mechanism having a brake shoe including a brake pad disposed thereon, wherein the brake shoe is adapted to be secured to a free end of a brake arm of the caliper-type braking mechanism. Additionally, the present invention is directed to a method of fabricating a brake shoe adapted for use in a caliper-type braking mechanism.

The subject underground cable assembly protection system of this invention relates to a plurality of rigid substantially impact-resistant elongate protective channel members. Each of these channel members defines an enclosed compartment for housing the cable assembly. The system of the present invention also includes means for interconnecting adjoining channel members to each other. In this way, the underground cable assembly protection system can be formed. The channel member and/or the interconnecting means can comprise a polymeric material, and more preferably an impact-resistant polymeric material such as high-impact PVC or polyurethane. The channel member and/or the interconnecting means can comprise a substantially U-shaped cross-sectional configuration, more preferably the substantially U-shaped cross-sectional configuration of each the channel member comprises a horizonal base section having a pair of respective ends and a pair side sections attached to the pair of respective ends of the horizonal base section. The adjoining channel members of this invention typically form a joint therebetween and the interconnecting means, which is preferably a lap joint section, that overlaps the joint and in turn the adjoining channel members.
