## Abstract

A rolling cart has a wheeled frame, telescoping vertically extendable members with glide strips, and a tiltable frame having glide strips interspersed with transfer balls to easily slide slabs or sheet materials for construction such as when installing countertops. A method is also described for measuring a minuend desired install height, subtracting a geometrically predetermined subtrahend, and adjusting the height from a floor surface to a pivot axis on the cart to equal the difference, said adjustment being effected by powered lifting means incorporated or ancillary to the cart.

## Claims

### Claim 1

A slab moving device comprising:
a rolling cart;
a generally planar frame, tiltably mounted on said cart; said frame tiltable between a horizontal and a vertical position;
at least one vertically extendable strut affixed to said rolling cart with said tiltable frame rotatably coupled to said vertically extendable strut so as to define a vertically adjustable pivot axis of said frame; and
at least one transit chock spaced apart from at least one of said vertically extendable strut to form a gap of a predetermined width, into which can be received said tiltable frame.

### Claim 2 (depends on 1)

The slab moving device of claim 1, further comprising: an operable strut extending mechanism.

### Claim 3 (depends on 2)

The slab moving device of claim 2, wherein said operable strut extending mechanism further comprises an extendable member which is also a damping member.

### Claim 4 (depends on 1)

The slab moving device of claim 1, wherein said strut extending mechanism is operated by a battery-powered motor.

### Claim 5 (depends on 4)

The slab moving device of claim 4, wherein said strut extending mechanism and said battery-powered motor are operated by remote control.

### Claim 6 (depends on 4)

The slab moving device of claim 4, wherein said strut extending mechanism and said battery powered motor are controlled by at least one switch.

### Claim 7 (depends on 6)

The slab moving device of claim 6, wherein at least one of said at least one switch is affixed to said tiltable frame.

### Claim 8 (depends on 1)

The slab moving device of claim 1, wherein said strut extending mechanism comprises a threaded shaft.

### Claim 9 (depends on 8)

The slab moving device of claim 8, wherein an end of said threaded shaft comprises a hexagonal cross-section.

### Claim 10 (depends on 1)

The slab moving device of claim 1, wherein said tiltable frame is fabricated from tubing in which at least one tube end is capped off by a bumper.

### Claim 11 (depends on 1)

The slab moving device of claim 1, further comprising:
adhesive-backed high-friction material affixed to at least one transit chock.

### Claim 12 (depends on 1)

The slab moving device of claim 1, further comprising:
adhesive-backed high-friction material affixed to said rolling cart.

### Claim 13 (depends on 1)

The slab moving device of claim 1, further comprising:
a plurality of support blocks made of a compliant material affixed to said rolling cart.

### Claim 14 (depends on 1)

The slab moving device of claim 1, further comprising:
at least one extendable member connected between said tiltable frame and said at least one vertically extendable member,
wherein said at least one extendable member further comprises a mechanical damper.
