1. Metal-to-metal contact of cam followers to steel turntable cause noise and high wear.
2. Chain and sprocket systems require proper lubrication and adjustment. Chain will sag and cause uneven wear of sprocket.
SUPPORT SYSTEM
Lantech NEW DESIGN
OLD DESIGN
38" precision ring bearing for high speed / heavy duty applications (6000 lb loads).
38" slew bearing.
Typically 20"-25" ring gear bearing.
Smaller diameter bearing does not distribute weight of load effectively.
33" bearing on some high speed models.

Automated Film Cut and Clamp Unit on Q-300 XT and Auto Film Cut-off on Q-300.
Remote START lanyard switch keeps driver on fortruck (Q-300 XT).
Improve productivity and plant flow.
Forktruck driver gets off/on forktruck to cut and tuck film, and start the wrapping cycle.
Inefficient use of forktruck and labor resources.
FILM DELIVERY PERFORMANCE

(1) No gaps. (2) 180 degree wrap-to-roller contact.
Two Critical Factors: 180 degree film-to-roller contact during stretch process. Floating nip roller maintains 180 degree contact of film-to-rollers and prevents film slippage. Result: Minmal neckdown of film web. Maximizes film stretch percentage. Eliminates film slippage across the stretch rollers. Neutralizes film breaks. Provides lowest film usage per load.
(1) Large unsupported gaps. (2) Insufficient wrap-to-roller contact. (3) Film neckdown.
Inconsistent Control of Film Stretching: Film contact to rollers is less than 180 degrees. Nip roller not used to eliminate gaps between rollers. Fixed nip roller does not engage pre-stretch roller for optimal film control. Result: Film slips across rollers reducing potential stretch level. 3" - 5" of neckdown is common. Uneven unitization of load from top to bottom. Film breaks are common. Cumulative result is higher packaging cost.
