Mobile Material Handling
System
CargoMaster cranes are small bridge cranes designed to operate on rails affixed to the walls of a van body or trailer. The major characteristics of the patented CargoMaster are described below:
FRAME - is constructed of structural steel, formed channels and steel plates of sufficient size and strength to carry the 2,000; 4,000; 6,000; and 8,000 pound load for which the machine is designed.
|
HYDRAULIC SYSTEM - exclusive of its power source is enclosed entirely within the frame of the crane. It is designed to provide power to the three movements the crane must perform:
(1) IN & OUT- A hydraulic motor is attached to a drive axle through a roller chain and sprocket combination that turns the drive wheels on the crane.
(2) LEFT & RIGHT- Another hydraulic motor is attached to a sprocket that drives a chain attached to both ends of a trolley to move it either left or right.
| |
(3) UP & DOWN-
A hydraulic cylinder is attached to a traveling block suspended from
the trolley through a cable and sheave arrangement. The traveling
block moves up and down as the cylinder rod extends and retracts.
|
One electric solenoid controlled valve is mounted in the frame to control each of the three movements.
POWER SOURCE – A combined electric motor, hydraulic pump and the hydraulic oil reservoir assembly is mounted in the frame of the crane. 12-volt electric power is conducted from the truck or tractor battery to a buss bar affixed to the right-hand rail. The power is conducted from the buss bar to the motor by a pick-up that slides along the buss bar. A ground shoe sliding on the left-hand rail completes the circuit.
CONTROLS – A hand-grip type control with electric toggle switches is connected to each solenoid valve by an extension cable. Power from the solenoid valves is provided from the same buss bar that conducts current to the crane. (Remote controls are also available.)
INSTALLATION - Rails are installed on both interior walls a short distance below the ceiling. The rails consist of structural channels that are mounted with the web against the wall. A formed channel is attached on the top flange of each rail, which provides the track in which the four wheels run. Rail extensions are mounted and hinged to both sides at the rear to extend the rail length from 4 to 5 feet beyond the rear door of the truck or trailer. This enables the crane to carry the load outside the trailer. Double-fold rail extensions are available on the 2,000 and 4,000 pound models to handle long loads. The supporting gussets for the rails are welded directly to the steel body posts. If the posts are aluminum or fiberglass, reinforcing steel strips or posts must be bolted or riveted to the walls or posts to provide a surface for welding the supporting gussets. Detailed installation instructions and all necessary hardware are furnished with each crane when delivered.
ACCESSORIES – These are attached to the traveling block. Pallet forks, spreader bars, barrel clamps and swivel hooks are available for picking up different types of loads.
