The top surface of an insert abuts with a form, with a tube extending into an aperture and sliding on a form post in the form. A rod inserted through the form, form post and tube holds the insert in place while castable material is poured in. The form is inverted with the guard rail base inside, the rod can be slid out of the form, and the form is removed. The handle is gripped by a claw on the obtuse angled chassis of a transporter. A handle on the chassis can be pushed to raise the guard rail base and to move the guard rail base on the surface by wheels. The guard rail base can be placed upon a pad having notches in its border.

Devices, systems, and methods are provided for helping hand trucks lift heavy objects. A device for attaching to hand trucks and lifting objects may include a pallet portion for lifting weight, the pallet portion having a bottom portion facing the ground and a top portion, wherein weight is arranged on the top portion; an angle maintaining portion attached to the bottom portion, wherein when the angle maintaining portion is touching the ground, the pallet portion is positioned at an angle greater than zero relative to the ground; and one or more slots attached to the bottom portion, wherein the one or more slots are configured to attach to a hand truck nose blade by sliding the hand truck nose blade into the one or more slots.

A hand truck utilizes a pair of permanent magnet unit to secure two metallic cylindrical objects to the hand truck. Each permanent magnet unit has a forward-facing clamping surface for engaging a side of a metallic cylindrical object. Each permanent magnet provides a selective magnetic field sufficient to secure the metallic cylindrical object to the forward-facing clamping surface of the permanent magnet. The pair of permanent magnet units may be simultaneously actuated by operation of a single actuation handle. The hand truck may be equipped with a pair of cylinder safety mechanisms by which an operator may selectively engage a safety plate beneath each of the metallic cylindrical objects. Each safety plate is independently rotatable by the operator thereby allowing each metallic cylindrical object to be separately released from the hand truck.
