A Storm Shelter which meets FEMA criteria and can be assembled from the inside, within an existing room of a house. The shelter includes connection members which are not joined to one another at their ends, and panels having C-shaped channel members which have apertures for bolting to the connection members and to each other. A reinforced door formed of a panel having C-shaped channels on its sides is mounted to swing inwardly whereby providing entry and exit.

A low profile lift apparatus including a lift platform which accommodates manufactured product on a support surface thereof and elevationally lifts the manufactured product to a vertical level or elevation generally coplanar with an elevated surface on an adjacent pallet is disclosed. The low profile lift apparatus includes a base adapted to rest on a floor with the lift platform interconnected to the base for movement between raised and lowered positions. In a lowered position, a lower surface of the lift platform rests on the floor to provide the lift assembly with a low profile. The lift apparatus of the present invention further includes an apparatus for moving the platform relative to said base. Such apparatus preferably includes circuitry for selectively moving the lift platform in a controlled fashion relative to the base.

Low profile lift assembly

A lifting apparatus which is readily portable between locations and whose design allows for readily replacement and/or repair of component parts thereof to enhance both serviceability and maintenance of the lifting apparatus is disclosed. The lifting apparatus includes a support table, a base frame disposed beneath the support table, a linkage assembly for maintaining the table and the base frame in generally parallel relation relative to each other as the table moves between raised and lowered positions, and a pneumatically operated actuator for moving the table between the raised and lowered positions. The base frame of the lifting apparatus defines at least one opening for allowing tines of a moving device to be inserted therethrough, thus, allowing the lifting apparatus of the present invention to be readily transported between locations. Fasteners used to releasably secure the pneumatically operated actuator to the base frame are elevated above the surface on which the lifting apparatus is positioned thereby enhancing serviceability of the pneumatically operated actuator. Additionally, the base frame includes gib structure arranged in operable combination with the linkage assembly and which includes releasable structure for enhancing service access to rollers forming part of the linkage assembly.

Portable lifting apparatus

Pallet level loading apparatus with a three-sided opened top enclosure and a bottom in which a cantilever-supported lifting platform is vertically movable. The lifting platform is driven by a hydraulic system housed in the rear wall of the enclosure. The platform may be locked in position at a predetermined height within the three-sided enclosure to permit its movement from place to place by a hand pallet or forklift. The apparatus further includes a torsion shaft. The torsion shaft arrangement distributes eccentric loads on the cantilever supported lifting platform so that the platform will not experience lateral tilt. Two vertical guide masts are arranged for receiving a roller arrangement of the lifting platform in order to prevent front and back platform tilt.

In a rotary tube locking mechanism, the rotary tube itself is expanded into and against a steel ring which journals the tube to form an obstruction. A guide plate cooperates with this obstruction to provide an anti-racking function.

The leveler is positioned upon the flat top surface of the truck apron at some predetermined position in front of the dock. In the down position the surface cover plate of the leveler is parallel with the flat top surface of the truck apron. The lifting is provided by hydraulic cylinders secured to the leveler inwardly from the rear whereby avoiding interference with ancillary dock equipment. Thus, an aperture can be provided in the rear to accommodate a truck restraining device.

Surface mounted truck leveler

An ambulatory power lift including a base and a movable lifting platform connected by a scissor lever assembly. Hydraulic power cylinders expand said scissor assembly in a manner which applies a substantially vertical lifting force to said platform. A modular power unit directs hydraulic fluid to said cylinders and allows the remote control of the lifting operation. A retractable bridge assembly on one end of the platform automatically raises as said lift is lowered, and a retractable wheel assembly allows the lift to be selectively transported in a lowered condition. A retractable guardrail closes at least one end of the lift platform. Safety means are also provided to prevent tampering with said power unit and to prevent entrapment between the platform and base.
